Variations in coding practices among Connecticut urologists for the Medicare population.
As health care costs continue to rise, alternatives to the traditional fee for service system of physician reimbursement are being explored. Recently a resource-based relative-value system was enacted by Congress to correct some of the perceived inequities of Medicare reimbursement. Since reimbursement for evaluation and management services, also known as cognitive services, are based on Current Procedural Terminology (CPT-4) codes, we reviewed Medicare claims data for fiscal year 1986-87 to identify the coding habits of Connecticut urologists. We found that Connecticut urologist file 99% of their claims for cognitive services in one of six categories. Furthermore, we found that within these broad categories an average of 82% of the claims were filed under one primary practice specific code. The particular code selected, however, varied markedly between practices. Our data suggest that Connecticut urologists have adopted different standards for using CPT-4 codes and have adjusted for these differences through their fee schedules. These findings highlight the need for increased precision in CPT code definitions for cognitive services before they can be adapted to a reimbursement system based upon relative-value scales.
