What 97804 covers
This service covers nutrition counseling delivered to two or more patients together by a registered dietitian or other qualified nutrition professional. The session may address topics such as meal planning, nutrition-related health goals, and strategies for managing a condition through diet. It is distinct from a one-to-one nutrition assessment or follow-up, even when the subject matter is similar.
Report the service in 30-minute units for each patient who participates in the group session. Documentation should support the session duration, group format, nutrition topics addressed, and each patient’s attendance and participation. Choose the individual nutrition therapy codes when the professional provides one-to-one care rather than a shared session. Under the Medicare Physician Fee Schedule, this code has work, practice expense, and malpractice RVUs; the practice expense RVU differs between office and facility settings.
