Evaluation & Management Coding Resources

IDSA has developed Evaluation and Management (E&M) coding resources specific to the practice of infectious diseases (ID). Given that ID physicians provide more of these services than almost any other specialty, understanding the E&M coding rules will help to maximize payments and minimize audit risk. Please click on the hyperlinks below for more information about these resources.

Non-Face-to-Face Prolonged Services

Beginning January 1, 2017, the Centers for Medicare & Medicaid (CMS) will provide payment for non-face-to-face prolonged services reported by CPT® codes 99358 and +99359 (Prolonged evaluation and management service before and/or after direct patient care; first hour, and each additional 30 minutes). Previously, the work associated with these codes was considered to be included in work for face-to-face evaluation and management (E&M) services. Information on the codes and the time requirements may be found here.
