## Title
Systems and methods for insurance underwriting

## Abstract

The systems and methods described herein may automate insurance underwriting by integrating information from multiple online databases and creating decision making advice useful to insurance underwriters. One system includes a client, database, and server. The client allows an underwriter to enter applicant information, enter customized risk modifiers, and receive an underwriting decision. The database provides additional applicant information. This information can include one or more of prescription drug history, credit history, motor vehicle records, and geocentric mortality risk. The server obtains the applicant information, calculates the applicant's risk, and makes an underwriting decision. Another system calculates a prescription drug risk for an applicant from pharmacy benefits management data, drug risk category data, and application data. Another system calculates a geocentric mortality risk for an applicant from census data, mortality data, credit information, and application data. Preset external modifiers are added to systems and methods of calculating risk in order to allow the underwriter to customize the risk results.

This application is a divisional of U.S. patent application Ser. No. 10/875,798, entitled “Systems and Methods for Insurance Underwriting,” filed Jun. 25, 2004, now U.S. Pat. No. 7,831,451 which claims the benefit of U.S. Provisional Patent Application Ser. No. 60/482,761, filed Jun. 27, 2003, the contents of which are hereby incorporated by reference in their entirety.


FIELD OF THE INVENTION
The invention generally relates to systems and methods for insurance underwriting, and in particular, to systems and methods that can integrate information from multiple online databases and create decision making advice useful to insurance underwriters.
BACKGROUND OF THE INVENTION
Underwriting is the process an insurance company uses to determine whether or not a potential customer is eligible for insurance, and the rate that that potential customer should pay for the insurance if eligible. The purpose of insurance underwriting is to spread risk among a pool of insured in a manner that is both fair to the customer and profitable for the insurer. Like other businesses, insurance companies need to make a profit. Therefore, it does not make sense for them to sell term insurance, for example, to everyone who applies for it. Although they do not want to make customers pay an excessively high rate, it is not wise for them to charge all their policyholders the same premium. Underwriting enables the company to “weed out” certain applicants and to charge the remaining applicants premiums that are commensurate with their level of risk.
Risk classification determines to a significant degree the premium a customer will pay for insurance. Four typical risk groups are: standard, preferred, substandard, and uninsurable. Each of these is explained below.
Standard risks: These are individuals who, according to the insurance company's underwriting standards, are entitled to term insurance without having to pay a rating surcharge or be subjected to policy restrictions.
Preferred risks: This group includes individuals whose mortality experience (i.e., life expectancy) as a group is expected to be above average and to whom the company offers a lower than standard rate. The most common preferred class today is nonsmokers, for whom many insurers now offer a favorable rate.
Substandard risks: These are individuals who, because of their health and/or other factors, cannot be expected (on average) to live as long as people who are not subject to these risk factors. Substandard applicants are insurable, but only at higher than standard rates that reflect the added risk. Policies issued to substandard applicants are referred to as rated or extra risk policies.
Uninsurable: These are applicants to whom the company refuses to sell term insurance because they are unwilling to shoulder the risks. They have decided that the risk factors associated with the applicant are too great or too numerous. In other cases, the applicant's circumstances may be so rare or unique that the company has no basis to arrive at a suitable premium.
An insurance company typically looks at a number of factors during the underwriting process in order to evaluate a potential customer in terms of risk. These factors enable the insurer to decide whether or not the potential customer is insurable. If the potential customer is insurable, these factors help place them into the appropriate risk group. Some of the factors considered are age, sex, current health/physical condition, personal health history, family health history, financial condition, personal habits/character, occupation, and hobbies.
An insurance company will gather information about potential customers from several sources. In the case of term insurance, the basic source of underwriting information is a completed customer application. The questions on the application are designed to give the insurer much of the information needed to make a decision. The company will then either reject an application, accept it and offer insurance at a certain rate, or seek additional information. In many cases, the company places great weight on the recommendations of a broker or insurance agent, particularly if the broker or agent has a good track record with the company. In some cases, an insurer may request a report from an independent company that specializes in the investigation of personal matters. This inspection report may provide the insurer with a wide range of personal information about a potential customer above and beyond what is on the application. In addition to an inspection report, the insurer may seek information on a potential customer from one of the cooperative information bureaus the insurance industry supports. The best known example is the Medical Information Bureau (MIB), which maintains centralized files on the physical condition of individuals who have applied for life insurance with member companies. In life insurance, one of the primary factors in assessing risk is an individual's health. Accordingly, it is no surprise that one of the most important sources of underwriting information is a physical exam. After examining a potential customer, a physician selected by the insurance company supplies the company with a detailed medical report. This report generally tells the company all it needs to know about the potential customer's present health.
The underwriting process is currently a manual process. It can involve numerous people including agents and doctors, and it can be very time-consuming. In view of the foregoing, it can be appreciated that a substantial need exists for systems and methods that can automate the underwriting process, improve decision-making, reduce the number of people involved and speed the overall process.
SUMMARY OF THE INVENTION
Embodiments of the present invention relate to systems and methods for automating insurance underwriting by integrating information from multiple online databases and creating decision making advice useful to insurance underwriters. The first embodiment of the present invention is a system for insurance underwriting including a client, a database, and a server. The client allows information about an insurance applicant obtained from the applicant to be entered into the system and an underwriting decision determined for the insurance applicant to be returned from the system. The database contains information about the applicant not obtained from the applicant. It can include but is not limited to prescription drug histories, credit histories, motor vehicle records, and geocentric mortality indices. The server obtains applicant information entered through the client, retrieves applicant information contained in the database, calculates an insurance risk from the applicant information entered through the client and the applicant information contained in the database, translates the insurance risk into an underwriting decision and returns the underwriting decision to the client. The insurance risk calculated by the server and returned to the client may be a risk score, a risk classification, or both. This embodiment may further include a modifier entered into the system through the client that is used by the server to modify the insurance risk determined by the server and returned to the client.
A second embodiment is directed to a system for insurance underwriting based on prescription drug histories. The system includes a pharmacy benefits management database, a drug risk category database, a list of applicant characteristics, and a processor. The pharmacy benefits management database contains a list of prescription drugs for each individual in the pharmacy benefits management database and information about each prescription drug on the list including but not limited to a national drug code, a number of individual doses dispensed, and a date each of the individual doses were dispensed. The drug risk category database contains prescription drugs grouped into one or more specific disease categories that could contribute to premature death including but not limited to cardiovascular, cancer, smoking, hepatitis, HIV infection, diabetes, substance abuse, pulmonary, gastrointestinal, renal, psychological, neurological, endocrine, rheumatological, musculoskeletal, hematological, and a category for drugs not fitting into any of the other categories. The list of applicant characteristics includes but is not limited to one or more of sex, birth date, height, weight, and smoking status. The processor obtains an insurance applicant's list of prescription drugs, their dosages and dates they were dispensed from the pharmacy benefits management database, matches the list of prescription drugs to disease categories from the drug category database, calculates a risk score for the insurance applicant based on the disease categories matched and the list of prescription drugs dosages and dates, and modifies the risk score according to the list of applicant characteristics. This embodiment may further include a second processor that modifies the risk score calculated by the processor according to a modification scheme preset externally by an underwriter. This modification scheme may be a translation table that the second processor uses to translate the risk score calculated by the processor into a second risk score. Alternatively, this modification scheme may be a multiplier that the second processor multiples the risk score calculated by the processor by to produce a second risk score.
A third embodiment of the present invention is a method for calculating a prescription drug risk score for an insurance applicant. This method has several steps, although it will be appreciated that two or more of the following steps could be collapsed into a single step, or one or more of these steps may be broken up into even more steps. In a first step, a list of prescription drug for the insurance applicant is obtained from a pharmacy benefits management database. The pharmacy benefits management database contains a list of prescription drugs for each individual in the pharmacy benefits management database and information about each prescription drug on the list including but not limited to a national drug code, a number of individual doses dispensed, and a date each of the individual doses were dispensed. In a second step, a list of characteristics of the insurance applicant is obtained. The list of characteristics of the insurance applicant includes but is not limited to one or more of sex, birth date, height, weight, and smoking status. In a third step, the list of drug risk categories for the insurance applicant is obtained from a drug risk category database. The drug risk category database contains prescription drugs grouped into one or more specific disease categories that could contribute to premature death comprising cardiovascular, cancer, smoking, HIV infection, diabetes, substance abuse, pulmonary, hepatitis, gastrointestinal, renal, psychological, neurological, endocrine, rheumatological, musculoskeletal, hematological, and a category for drugs not fitting into any of the other categories. In a fourth step, a body mass index of the insurance applicant is calculated from the list of characteristics and if the body mass index cannot be calculated a default value is used. The body mass index of the insurance applicant is calculated by dividing the weight in kilograms by the height in meters squared. In a fifth step, the risk score of each of the drug risk categories for the insurance applicant is set to the default no risk value.
In a sixth step, one or more drug risk categories and a risk score of a prescription drug are determined from the list of prescription drugs by querying the drug risk category database with the insurance applicant's sex and a code for the prescription drug. In a seventh step, it is determined if the prescription drug is a different representation of a drug already processed. This step involves comparing drug categorization, dosage, and route of administration of the prescription drug with categorization, dosage, and routes of administration of all other drugs on a list of processed prescription drugs in order to determine if the prescription drug is a different representation of a drug already processed, discarding the prescription drug if it is a different representation of a drug already processed, and adding the prescription drug to the list of processed prescription drugs if it is not a different representation of a drug already processed. In an eighth step, it is determined if a drug category of the prescription drug is smoking. If it is, the smoking status of the insurance applicant is set to smoking. In a ninth step, a risk score of the prescription drug is modified based on the date of dispensing. This modification involves multiplying the risk score of the prescription drug by a modifier specified in a table containing different modifiers for different date ranges from the data of dispensing. In the tenth step, a risk score of the prescription drug is modified based on the refill pattern. This modification involves multiplying the risk score of the prescription drug by a modifier specified in a table containing different modifiers for different amounts of refills within different time periods.
In an eleventh step, the prescription drug is added to one or more drug risk categories for the insurance applicant. In a twelfth step, the risk scores of each drug risk category are calculated from the risk scores of prescription drugs in each drug risk category. This involves examining each prescription a drug risk category, finding a prescription drug with the highest risk score within the drug risk category, and adding to a risk score of the prescription drug with the highest risk score within the drug risk category a number of unique, non-zero risk prescription drugs in the drug risk category multiplied by a factor. In a thirteenth step, the drug risk category with a highest risk score is determined. In a fourteenth step, all prescription drugs found in the drug risk category with the highest risk score are removed from all other drug risk categories to prevent biasing from multiple purpose prescription drugs. The risk scores of drug categories from which prescription drugs were removed are then recalculated.
In the fifteenth step, a risk score of the drug risk category with the highest risk score is modified according to the smoking status of the insurance applicant and the drug risk category. One modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cancer, pulmonary, cardiovascular, and diabetes and the smoking status of the insurance applicant comprises smoking. Another modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises pulmonary and the smoking status of the insurance applicant comprises non-smoking. In a sixteenth step, a risk score of the drug risk category with the highest risk score is modified according to the body mass index of the insurance applicant and the drug risk category. One modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cancer, HIV infection, smoking, neurological, musculoskeletal, endocrine, and hematological and the body mass index is less than 19 and greater than or equal to 17. A second modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises psychological and the body mass index is less than 19 and greater than or equal to 17. A third modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cardiovascular and diabetes and the body mass index is less than 35 and greater than or equal to 32.
In a final step, a final prescription drug risk factor is calculated by multiplying the individual drug score of the second and third highest risk categories by constants and adding these values to the risk score of the drug risk category with the highest risk score. An exemplary calculation involves multiplying a drug score of the second highest risk category by 0.5 and a drug score of the third highest risk category by 0.25 and adding these values to the risk score of the drug risk category with the highest risk score.
This embodiment may include removing the risk contribution from the category for drugs not fitting into any of the other categories if the drug risk category with the highest risk score is not the category for drugs not fitting into any of the other categories. It may also include modifying the final prescription drug risk by a preset external factor set by an underwriter.
A fourth embodiment of the present invention is a system for insurance underwriting based on geocentric mortality data. This system includes a census database, a mortality database, a credit information database, a list of applicant characteristics, and a processor. The list of applicant characteristics includes but is not limited to one or more of sex, age, income, account balances, number of accounts, credit limits, original mortgage amount, and mortgage account balance. The processor obtains population data for a region of an insurance applicant from the census database, gathers mortality data for the region of the insurance applicant from the mortality database, retrieves financial data for the region of the insurance applicant from the credit information database, generates a mortality table for the region of the insurance applicant based on age, sex and financial information, and calculates a geocentric mortality risk score for the insurance applicant by comparing the list of applicant characteristic with the mortality table. This embodiment may include a second processor that modifies the geocentric mortality risk score calculated by the processor according to a modification scheme preset externally by an underwriter.
A fifth embodiment of the present invention is method for calculating a geocentric mortality risk score for an insurance applicant. This method also has several steps. In a first step, a table containing populations of a region in which the insurance applicant lives grouped by age and sex is obtained. In a second step, a table containing the number of deaths that have occurred in the region in which the insurance applicant lives grouped by age and sex is obtained. In a third step, a table containing the financial data of households in the region in which the insurance applicant lives grouped by age and sex is obtained. In a fourth step, a mortality table for the region in which the insurance applicant lives based on financial data, age, and sex is generated. In a fifth step, a list of applicant characteristics about the insurance applicant is obtained. The list of applicant characteristics includes but is not limited to one or more of sex, age, income, account balances, number of accounts, credit limits, original mortgage amount, and mortgage account balance. In a sixth step, a geocentric mortality risk score is calculated by comparing the list of applicant characteristics to the mortality table. This embodiment may include an additional step of modifying the geocentric mortality risk score by a preset external factor set by an underwriter.
A sixth embodiment of the present invention is a system for insurance underwriting. The system includes but is not limited to a first processor that determines prescription drug risk, a second processor that determines geocentric mortality risk, a third processor that determines motor vehicle records risk, a fourth processor that determines credit information risk, a list of risks based on an applicant's application information, and a fifth processor. The fifth processor calculates an overall risk score by combining one or more of the risk scores of the first processor, the second processor, the third processor, the fourth processor, and the risks based on an applicant's application information. This embodiment may also contain a translation table used by the fifth processor to translate the risk scores of the first processor, the second processor, the third processor, the fourth processor and the risks based on an applicant's application information based on preset external factors set by the underwriter.
A seventh embodiment of the present invention is a method for calculating overall risk for an insurance applicant. In a first step, a first risk score is calculated based on a prescription drug history of the insurance applicant. In a second step, a second risk score for the insurance applicant is calculated based on a geocentric mortality data. In a third step, a third risk score is calculated based on a motor vehicle report history of the insurance applicant. In a fourth step, a fourth risk score is calculated based on a credit report for the insurance applicant. In a fifth step, additional risk parameters from the application data of the insurance applicant are gathered. In a final step, the overall risk for the insurance applicant is generated by combining one or more of the first risk score, the second risk score, the third risk score, the fourth risk score, and the additional risk parameters. This embodiment may also include the additional step of modifying the first risk score, the second risk score, the third risk, the fourth risk score, and the additional risk parameters based on a translation table provided as preset external data from an underwriter.

Before one or more embodiments of the invention are described in detail, one skilled in the art will appreciate that the invention is not limited in its application to the details of construction, the arrangements of components, and the arrangement of steps set forth in the following detailed description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
DETAILED DESCRIPTION
FIG. 1 is a schematic diagram showing two paths of communication between a client and a server in an insurance underwriting system containing a client, a database, and a server in accordance with an embodiment of the present invention. In underwriting system 100, client 110 allows information about an insurance applicant obtained from the applicant to be entered into system 100. Exemplary methods of obtaining this information include an agent or underwriter receiving it orally from the applicant and entering it into system 100, an agent or underwriter transcribing it from a written application into system 100, or applicant entering the data directly where system 100 is an online system. In these examples, the users of client 110 are an agent, an underwriter, or an applicant. This information is sent from client 110 to server 120 for processing via communications path 130. Client 110 also receives output from the system. This output is in the form of an underwriting decision determined by server 120 for the insurance applicant. An underwriting decision is the decision to write a policy for the applicant, to not write a policy for the applicant, or to refer the applicant to another underwriting process. The underwriting decision determined by server 120 for the insurance applicant is sent to client 110 via communications path 140.
Database 150 contains information about the applicant not obtained from the applicant. This information can include but is not limited to prescription drug histories, credit histories, motor vehicle records, and geocentric mortality indices. Database 150 is used to gather additional information about an applicant and to verify information already known about an applicant. Server 120 queries database 150 and receives this information via communications path 160.
Server 120 is the processor of underwriting system 100. Server 120 obtains applicant information entered through client 110. It retrieves applicant information contained in database 150. It calculated the insurance risk of the applicant from the applicant information entered through client 110 and the applicant information contained in database 140. Exemplary insurance risks provided by underwriting systems include a risk score and a risk classification. A risk score is a numeric value within a numeric range of risk. A risk classification is a grouping of applicants based on risk, as was described earlier. Server 120 translates the insurance risk into an underwriting decision. An exemplary server 120 translates a risk score into an underwriting decision by calling one range of risk scores a decision to underwrite a policy, a second range of risks scores a decision to refer the applicant to traditional underwriting, and a third range of risk scores a decision not to underwrite a policy. Similarly, an exemplary server 120 translates a risk classification through the use of a lookup table. For an uninsurable classification the underwriting decision is not to write a policy. For classifications substandard to preferred the decision is to underwrite the policy but at decreasing premiums for each of the classifications. Finally, server 120 returns the underwriting decision to client 110.
The method used by server 120 to determine the insurance risk varies depending on the database used. Also, if more than one database 150 is used, server 120 calculates the risk according to each database 150 and then calculates an overall insurance risk for the applicant. The use of one or many databases is under the control of the underwriter or agent in system 100. The underwriter or agent can then explore more than one scenario utilizing one or more databases. Server 120 then provides a type of programming interface for the underwriting process. When system 100 is configured as an online system to be accessed by applicants, the use of one or more databases is preset or varied according the information provided by the applicant.
FIG. 2 is a schematic diagram showing three paths of communication between a client and a server in an insurance underwriting system containing a client, a database, and a server in accordance with an embodiment of the present invention. In system 200, client 110 allows a modifier to be entered into the system that will modify the insurance risk determined by server 120 and returned to client 110. This modifier is entered via communication path 210. An exemplary modifier is a multiplier that is multiplied by the risk score to change its value. Another exemplary modifier is a translation table. A translation table is used to change the value of risk scores within a certain range to a specified value. Modifiers are used by underwriters to customize the underwriting results according to their experience. They are also used to enable the results to match the input parameters of other automated systems. If one or more databases 150 are used, then one or more modifiers are entered into the system through client 110. Communications paths 130, 140, 160, and 210 provide data communications via one or more computer networks.
FIG. 3 is schematic diagram of a system for insurance underwriting based on prescription drug histories in accordance with an embodiment of the present invention. System 300 includes pharmacy benefits management (PBM) database 310, drug risk category database 320, list of applicant characteristics 330, and prescription drug underwriting processor 340. PBM database 310 contains a list of prescription drugs for each individual in PBM database 310. It also includes information about each prescription drug on the list including but not limited to a national drug code, a number of individual doses dispensed, and a date each of the individual doses were dispensed. Drug risk category database 320 contains prescription drugs grouped into one or more specific disease categories that could contribute to premature death. These categories include but are not limited to cardiovascular, cancer, smoking, hepatitis, HIV infection, diabetes, substance abuse, pulmonary, gastrointestinal, renal, psychological, neurological, endocrine, rheumatological, musculoskeletal, hematological, and a category for drugs not fitting into any of the other categories. List of applicant characteristics 330 contains information about the applicant obtained from the applicant. This information is obtained during the application process and includes but is not limited to one or more of sex, birth date, height, weight, and smoking status. Processor 340 retrieves an insurance applicant's list of prescription drugs, their dosages and dates they were dispensed from the pharmacy benefits management database. It matches the list of prescription drugs to disease categories from drug category database 320. It calculates a risk score for the insurance applicant based on the disease categories matched and the list of prescription drugs dosages and dates dispensed. Finally, it modifies the risk score according to the list of applicant characteristics to produce the prescription drug risk score 350.
FIG. 4 is schematic diagram of a system for insurance underwriting based on prescription drug histories including a second processor that modifies the original risk score in accordance with an embodiment of the present invention. In system 400, a second processor 410 modifies the risk score calculated by the processor 340 according to a modification scheme preset externally by an underwriter. This modification scheme may be a translation table that second processor 410 uses to translate the risk score calculated by processor 340 into a second risk score. Alternatively, this modification scheme may be a multiplier that second processor 410 multiples the risk score calculated by processor 340 by to produce second risk score 420.
FIG. 5 is a flowchart showing a first series of steps of a method for calculating a prescription drug risk score for an insurance applicant in accordance with an embodiment of the present invention. A series of steps will be described with respect to this method, but those skilled in the art will appreciate that some of these steps may be combined or further broken down into yet additional steps.
In step 501 of method 500, a list of prescription drugs for the insurance applicant is obtained from a pharmacy benefits management database. The pharmacy benefits management database contains a list of prescription drugs for each individual in the pharmacy benefits management database and information about each prescription drug on the list including but not limited to a national drug code, a number of individual doses dispensed, and a date each of the individual doses were dispensed.
In step 502, a list of characteristics of the insurance applicant is obtained. The list of characteristics of the insurance applicant includes but is not limited to one or more of sex, birth date, height, weight, and smoking status.
In step 503, the list of drug risk categories for the insurance applicant is obtained from a drug risk category database. The drug risk category database contains prescription drugs grouped into one or more specific disease categories that could contribute to premature death comprising cardiovascular, cancer, smoking, HIV infection, diabetes, substance abuse, pulmonary, hepatitis, gastrointestinal, renal, psychological, neurological, endocrine, rheumatological, musculoskeletal, hematological, and a category for drugs not fitting into any of the other categories.
In step 504, a body mass index of the insurance applicant is calculated from the list of characteristics and if the body mass index cannot be calculated a default value is used. An exemplary default value is 25. The body mass index of the insurance applicant is calculated by dividing the weight in kilograms by the height in meters squared.
In step 505, the risk score of each of the drug risk categories for the insurance applicant is set to the default no risk value. This is an initialization step since the drug risk categories are used later to calculate the final risk value.
In step 506, one or more drug risk categories and a risk score of a prescription drug are determined from the list of prescription drugs by querying the drug risk category database with the insurance applicant's sex and a code for the prescription drug. The national drug code of each prescription drug is used to query the drug risk category database. The database is also segregated with respect to gender, so the sex of the applicant is also used in the query. From querying the drug risk category database the initial risk score of each drug is found. The category or categories to which each prescription drug belongs is also determined. The list of drug risk categories includes, but is not limited to, cardiovascular, cancer, smoking, hepatitis, HIV infection, diabetes, substance abuse, pulmonary, gastrointestinal, renal, psychological, neurological, endocrine, rheumatological, musculoskeletal, hematological, and a category for drugs not fitting into any of the other categories. Exemplary risk values for a prescription are from a range between 0 and 90 and including 0 and 90, where 0 is no risk and 90 is the highest risk possible for a single drug.
In step 507, it is determined if the prescription drug is a different representation of a drug already processed. Obviously, drugs with the same national drug code are the same drug, but different manufacturers and especially generic drugs may be identical, yet have different codes. This step involves comparing drug categorization, dosage, and route of administration of the prescription drug with categorization, dosage, and routes of administration of all other drugs on a list of processed prescription drugs in order to determine if the prescription drug is a different representation of a drug already processed. A prescription drug is discarded if it is a different representation of a drug already processed. Drugs not already processed are added to the list of processed prescription drugs.
In step 508, it is determined if a drug category of the prescription drug is smoking. If it is, the smoking status of the insurance applicant is set to smoking. Exemplary values for the smoking status of an applicant include smoking, non-smoking, and prior smoking.
FIG. 6 is a flowchart showing a second series of steps of a method for calculating a prescription drug risk score for an insurance applicant in accordance with an embodiment of the present invention.
In step 509 of method 500, a risk score of the prescription drug is modified based on the date of dispensing. This modification involves multiplying the risk score of the prescription drug by a modifier specified in a table containing different modifiers for different date ranges from the data of dispensing. An exemplary modifier for a prescription drug not dispensed in the past two years is 0.50. An exemplary modifier for a prescription drug dispensed within the past two years is 0.75.
In the step 510, a risk score of the prescription drug is modified based on the refill pattern. This modification involves multiplying the risk score of the prescription drug by a modifier specified in a table containing different modifiers for different amounts of refills within different time periods. An exemplary modifier for a prescription drug with up to 6 refills in a two year period is 0.75. An exemplary modifier for a prescription drug with between 6 and 12 refills in a two year period is 0.75.
In step 511, the prescription drug is added to one or more drug risk categories for the insurance applicant.
In step 512, the risk scores of each drug risk category are calculated from the risk scores of prescription drugs in each drug risk category. This involves examining each prescription a drug risk category and finding the prescription drug with the highest risk score within the drug risk category. The risk score of the drug risk category is then calculated by counting the other of unique, non-zero risk prescription drugs in the drug risk category, multiplying this count by a factor, and adding this value to the risk score of the prescription drug with the highest risk score within the drug risk category.
In step 513, the drug risk category with a highest risk score is determined. This is determined by comparing the risk scores of all the drug risk categories for the applicant.
In step 514, all prescription drugs found in the drug risk category with the highest risk score are removed from all other drug risk categories to prevent biasing from multiple purpose prescription drugs. The risk scores of drug categories from which prescription drugs were removed are then recalculated.
In step 515, a risk score of the drug risk category with the highest risk score is modified according to the smoking status of the insurance applicant and the drug risk category. One modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cancer, pulmonary, cardiovascular, and diabetes and the smoking status of the insurance applicant comprises smoking. Another modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises pulmonary and the smoking status of the insurance applicant comprises non-smoking.
In step 516, a risk score of the drug risk category with the highest risk score is modified according to the body mass index of the insurance applicant and the drug risk category. One modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cancer, HIV infection, smoking, neurological, musculoskeletal, endocrine, and hematological and the body mass index is less than 19 and greater than or equal to 17. A second modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises psychological and the body mass index is less than 19 and greater than or equal to 17. A third modification is multiplying the risk score of the drug risk category with the highest risk score by a constant if the drug risk category comprises cardiovascular and diabetes and the body mass index is less than 35 and greater than or equal to 32.
In step 517, a final prescription drug risk factor is calculated by multiplying the individual drug score of the second and third highest risk categories by constants and adding these values to the risk score of the drug risk category with the highest risk score. An exemplary calculation involves multiplying a drug score of the second highest risk category by 0.5 and a drug score of the third highest risk category by 0.25 and adding these values to the risk score of the drug risk category with the highest risk score.
Method 500 can include a number of additional steps. One step is modifying a risk score of the prescription drug based on a dosage pattern. This involves multiplying the risk score of the prescription by a modifier specified in a table containing different modifiers for different dosages of the prescription drug. An exemplary dosage multiplier is 0.70 for a very low dose. Another exemplary multiplier is 0.90 for a high dose.
Another additional step is removing the risk contribution from the category for drugs not fitting into any of the other categories, if the drug risk category with the highest risk score is not the category for drugs not fitting into any of the other categories.
A final additional step is modifying the final prescription drug risk by a preset external factor set by an underwriter.

Exemplary motor vehicle records risk is calculated based on violations or accidents. Exemplary credit information risk is calculated based on net worth, outstanding loans, account balances, or unpaid bills. Exemplary risks based on an applicant's application information include occupation, avocation, and whether or not the applicant is a smoker. Fifth processor 1060 calculates overall risk score 1070 by combining one or more of the risk scores of the first processor 1010, second processor 1020, third processor 1030, fourth processor 1040, and list of risks based on an applicant's application information 1050. An exemplary method of combining the risk scores is to add them with or without first applying weighting factors.
FIG. 11 is schematic diagram of a system for insurance underwriting based on prescription drug risk, geocentric mortality risk, motor vehicle records risk, credit information risk, risks based on an applicant's application information, and a translation table in accordance with an embodiment of the present invention.
