SIC-IR Billing and Documentation

Accurate documentation in the patient medical record is critical to ensure proper diagnosis coding and subsequent hospital reimbursement. Multiple studies have demonstrated that clinicians often omit diagnoses which may result in insurance company denials and significant delays in payment. In addition, omitting diagnoses decreases the severity of patient illness which is often used as a risk adjustment tool to compare institution and physician outcomes. Medical informatics has been used to help improve accurate diagnosis documentation as well as improve billing efficiency. We plan to utilize a medical informatics program called SIC-IR (Surgical Intensive Care - Infection Registry) to improve documentation and attending billing efficiency within the surgical and trauma intensive care unit (STICU). We propose a six month study: a three month observational evaluation of current billing procedures followed by a three month prospective evaluation using a newly created SIC-IR billing module. The outcome measures will include the number of ICD-9 and CPT codes at discharge per patient, severity of patient illness based on documentation, STICU charges, number of insurance company denials, DRG relative weights, as well as a qualitative assessment of attending physician use of the electronic billing module. The observational and prospective patient populations will be compared for total patient-days in the STICU, ventilator-days, antibiotic-days, infectious complications per patient, and injury severity score (trauma patients only) to ensure the populations are similar and only the documentation and billing changes can account for our measured outcomes. We hypothesize that the SIC-IR billing module will increase the number of patient ICD-9 and CPT codes at discharge, increase severity of STICU patient illness via accurate documentation, increase total STICU charges, decrease insurance company denials, and be an efficient and well accepted electronic medical application.

1. An observational evaluation will be performed for all STICU patients over a three month time period.

   1. Data collected will be the outcome measures listed above (Number of ICD-9 codes at discharge, number of CPT codes at discharge, ext)
   2. In addition the total number of STICU patient-days, ventilator-days, central line-days, confirmed infectious complications, injury severity scores for trauma patients, and antibiotic-days will be collected over the three month period. This will serve as a way to ensure the observational and prospective populations are not different, and only the documentation and billing methods changed.
2. The SIC-IR billing module will be released on October 1st, 2007 after attending physician training on its use.
3. A prospective evaluation will be performed for all STICU patients over a three month time period

   1. Data collected will be the outcome measures listed above (Number of ICD-9 codes at discharge, number of CPT codes at discharge, ext)
   2. In addition the total number of STICU patient-days, ventilator-days, central line-days, confirmed infectious complications, injury severity scores for trauma patients, and antibiotic-days will be collected over the three month period. This will serve as a way to ensure the observational and prospective populations are not different, and only the documentation and billing methods changed.
4. After the 3 month prospective evaluation, the attending physicians will be given a survey to document their acceptance or rejection of the billing module.
5. The observational and prospective documentation and billing data will be compared.
