(Medicare Claims Processing Manual Crosswalk)

When required to submit drug rebate data for Medicaid rebates, submit N4 followed by the 11 -digit National Drug Code (NDC) in positions 01- 13 (e.g., N499999999999). Report the NDC quantity qualifier followed by the quantity beginning in position 14.  The D escription Field on Form CMS -1450 is 24 characters in length. An example of the methodology is illustrated below.

When coding HCPCS for outpatient services, the provider enters the HCPCS code describing the procedure here.  On inpatient hospital bills the accommodation rate is shown here.     HCPCS used for Medicare claims are available from Medicare contractors.    Health Insurance Prospective Payment System (HIPPS ) Rate Codes     The HIPPS rate code consists of the three- character resource utilization group (RUG) code that is obtained from the Grouper software program followed by a 2- digit assessment indicator (AI) that specifies the type of assessment associated with the RUG code obtained from the Grouper.  SNFs must use the version of the Grouper software program identified by CMS for national PPS as described in the Federal Register for that year.  The Grouper translates the data in the Long Term Care Resident Instrument into a case mix group and assigns the correct RUG code.  The AIs were developed by CMS.    The Grouper will not automatically assign the 2- digit AI, except in the case of a swing bed MDS that is will result in a special payment situation AI (see below).  The HIPPS rate codes that appear on the claim must match the assessment that has been transm itted and accepted by the State in which the facility operates.  The SNF cannot put a HIPPS rate code on the claim that does not match the assessment.    HIPPS Rate Codes used for Medicare claims are available from Medicare contractors.  As of October 1, 2019, SNF PDPM changes are effective (see 120ff. in Chapter 6 of this manual).    HIPPS Modifiers/Assessment Type Indicators     The assessment indicators (AI) were developed by CMS to identify on the claim, which of the scheduled Medicare assessments or off -cycle assessments is associated with the assessment reference date and the RUG that is included on the claim for payment of Medicare SNF services.  In addition, the AIs identify the Effective Date for the beginning of the covered period and aid in ensuring that the number of days billed for each scheduled Medicare assessment or off cycle assessment accurately reflect the changes in the beneficiary's status over time.  The indicators were developed by utilizing codes for the reason for assessment contained in section AA8 of the current version of the Resident Assessment Instrument, Minimum Data Set in order to ease the reporting of  such information.  Follow the CMS manual instructions for appropriate assignment of the assessment codes.    HIPPS Modifiers/Assessment Type Indicators used for Medicare claims are available from Medicare contractors.  As of October 1, 2019, SNF PDPM changes are effective (see 120ff. in Chapter 6 of this manual).    HCPCS Modifiers (Level I and Level II)     Form CMS -1450 accommodates up to four modifiers, two characters each.  See AMA publication CPT 20xx (xx= to current year) Current Procedural Terminology Appendix A - HCPCS Modifiers Section: Modifiers Approved for Ambulatory Surgery Center (ASC) Hospital Outpatient Use.  Various CPT (Level I HCPCS) and Level II HCPCS codes may require the use of modifiers to improve the accuracy of coding.  Consequently, reimbursement, coding consistency, editing and proper payment will benefit from the reporting of modif iers.  Hospitals should not report a separate HCPCS (five -digit code) instead of the modifier.  When appropriate, report a modifier based on the list indicated in the above section of the AMA publication.    HCPCS modifiers used for Medicare claims are available from Medicare contractors.    FL 45 -  Service Date     Required Outpatient. CMHCs and hospitals (with the exception of CAHs, Indian Health  Service hospitals and hospitals located in American Samoa, Guam and Saipan) report line item dates of service on all bills containing revenue codes, procedure codes or drug codes.  This includes claims where the from and through dates are equal.  This change is due to a HIPAA requirement.     There must be a single line item date of service (LIDOS) for every iteration of every revenue code on all outpatient bills (TOBs 013X, 014X, 023X, 024X, 032X, 033X, 034X, 071X, 072X, 073X, 074X, 075X, 076X, 077X (effective April 1, 2010), 081X, 082X, 083X, and 085X and on inpatient Part B bills (TOBs 012x and 022x).  If a particular service is rendered 5 times during the billing period, the revenue code and HCPCS code must be entered 5 times, once for each service date.    FL 46 -  Units of Service     Required . Generally, the entries in this column quantify services by revenue code category, e.g., number of days in a particular type of accommodation, pints of blood.  However, when HCPCS codes are required for services, the units are equal to the number of times  the procedure/service being reported was performed.    The provider enters up to seven numeric digits. It shows charges for noncovered services as noncovered, or omits them.  NOTE: Hospital outpatient departments report the number of visits/sessions when billing under the partial hospitalization program or the intensive outpatient program .    FL 47 -  Total Charges -  Not Applicable for Electronic Billers    Required .  This is the FL in which the provider sums the total charges for the billing period for each revenue code (FL 42); or, if the services require, in addition to the revenue center code, a HCPCS procedure code, where the provider sums the total charges for the billing period for each HCPCS code.  The last revenue code entered in FL 42 is 0001 which represents the grand total of all charges billed.  The amount for this code, as for all others is entered in FL 47.  Each line for FL 47 allows up to nine numer ic digits (0000000.00).  The CMS policy is for providers to bill Medicare on the same basis that they bill other payers.  This policy provides consistency of bill data with the cost report so that bill data may be used to substantiate the cost report.  Medicare and non- Medicare charges for the same department must be reported consistently on the cost report.  This means that the professional component is included on, or excluded from, the cost report for Medicare and non- Medicare charges.  Where billing for  the professional components is not consistent for all payers, i.e., where some payers require net billing and others require gross, the provider must adjust either net charges up to gross or gross charges down to net for cost report preparation.  In such cases, it must adjust its provider statistical and reimbursement (PS&R) reports that it derives from the bill.  Laboratory tests (revenue codes 0300 -0319) are billed as net for outpatient or nonpatient bill s because payment is based on the lower of charges for the hospital component or the fee schedule.  The A/B MAC (A or HHH) determines, in consultation with the provider, whether the provider must bill net or gross for each revenue center other than laborat ory.  Where gross billing is used, the A/B MAC (A or HHH) adjusts interim payment rates to exclude payment for hospital -based physician services.  The physician component  must be billed to the Part B MAC  to obtain payment.  All revenue codes requiring HCPCS codes and paid under a fee schedule are billed as net.    FL 48 -  Noncovered Charges     Required . The total non- covered charges pertaining to the related revenue code in FL 42 are entered here.     FL 49 -  (Untitled)     Not used. Data entered will be ignored.     Note: the PAGE ____ OF ____ and CREATION DATE on line 23 should be reported on all pages of the UB -04.    FL 50A (Required), B (Situational), and C (Situational) -  Payer Identification     If Medicare is the primary payer, the provider must enter Medicare on line A.  Entering Medicare indicates that the provider has developed for other insurance and determined that Medicare is the primary payer.  All additional entries across line A (FLs 5 1-55) supply information needed by the payer named in FL 50A.  If Medicare is the secondary or tertiary payer, the provider identifies the primary payer on line A and enters Medicare information on line B or C as appropriate.    FL 51A (Required), B (Situational), and C (Situational)  Health Plan ID     Report the national health plan identifier when one is established; otherwise report the number Medicare has assigned.     FLs 52A, B, and C -  Release of Information Certification Indicator     Required . A Y code indicates that the provider has on file a signed statement permitting it to release data to other organizations in order to adjudicate the claim.  Required when state or federal laws do not supersede the HIPAA Privacy Rule by requiring that a signature be collected. An I code indicates Informed Consent to Release Medical Information for Conditions or Diagnoses Regulated by Federal Statutes.  Required when the provider has not collected a signature and state or federal laws do not supersede the HIPAA Privacy Rule by requiring a signature be collected.    NOTE: The back of Form CMS -1450 contains a certification that all necessary release statements are on file.    FL 53A, B, and C -  Assignment of Benefits Certification Indicator     Not used.
