title: The correlation of family physician work with submitted codes and fees.
abstract: OBJECTIVE
  The income disparity between primary care and other physicians has been attributed in part to the evaluation and management (E/M) rules written by CMS. The purpose of this study was to examine the relationship between family physicians' work and their actual coding practices and fees collected under these widely used rules.
  
  
  METHODS
  This was a direct observational time-motion study.
  
  
  METHODS
  A diverse group of 15 family physicians were shadowed over consecutive patient visits at their ambulatory practices, usually for a half-day of clinic. Data about each visit were recorded, including time parameters; number of issues covered; number of labs, images, and chronic prescriptions ordered; the physician fee code from the Current Procedural Terminology (CPT) system that was submitted; the actual payer for each patient; and the actual fee collected. The primary outcome was the correlation between the time spent for each patient's care and coding/financial measures.
  
  
  RESULTS
  The average total time a physician spent per patient including documentation time was 20.0 minutes. The average fee collected was $101.40, including patient co-pays. The correlation between the actual fee collected and the physician's time spent working on each patient's behalf was poor (R2 = 0.137, P < .001). There was a wide variation in times and fees for each CPT code category.
  
  
  CONCLUSIONS
  The existing E/M rules and CPT coding system have created office visit fees that correlate poorly with family physician work. These findings provide another justification for disruptive primary care payment reform.
