What 99374 covers
A physician reports this service for monthly oversight of a patient receiving home health care when the patient is not present. The work may include reviewing the care plan and updates on the patient’s status, considering related test results, and communicating with health professionals involved in the patient’s care to inform treatment decisions. It describes physician supervision, not a face-to-face home visit or a patient evaluation.
The time range is 15–29 minutes during one calendar month; 99375 is the higher-time home health supervision code. Medicare assigns 99374 physician fee schedule status B, meaning the code is bundled and Medicare never pays it separately. Its payment is included in payment for other services. The monthly time total supports code selection; it is not reported as multiple units for each call, record review, or care-planning task.
