What 99366 covers
99366 represents an interdisciplinary care conference conducted face to face with the patient, with or without family, by a participating nonphysician qualified health professional. The team brings together health care professionals from different disciplines to discuss the patient's care and coordinate their contributions. The conference is a team service, rather than a routine patient visit or a meeting held without the patient. It is reported when the conference lasts 30 minutes or more.
Medicare assigns this code physician fee schedule status B: payment is bundled, and Medicare never pays 99366 separately. The related conference codes distinguish meetings without the patient or family: 99367 is reported by a physician, while 99368 is reported by a nonphysician health professional. Documentation should identify the participants and disciplines, conference duration, and patient attendance; include family attendance when applicable.
