For most primary care physicians, Evaluation and Management services comprise the highest percentage of services performed, and account for most of the revenue.  Primary care physicians should regularly compare their profile with the norm for their specialty.  These specialty norms are included as a resource in this article.

Small changes in profiles can account for signinficant changes in revenue.  The Documentation Requirement differences between a 99213 and a 99214 are slight: it's a step between a 99213 and  a 99214, but a leap to the 99215.

In the most recent data available, Family Practice physicians billed 99214 more frequently than 99213!  That's a huge shift from ten years ago.  That file is also included in the resource section of this article.
