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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

99374 billing questions

How does 99374 differ from 99375?

Both describe physician supervision of a home health patient during a calendar month. Use 99374 for 15–29 minutes and 99375 for 30 minutes or more.

Does the patient need to be present?

No. This code describes physician oversight performed without the patient present, such as reviewing care information and communicating with professionals involved in the patient’s care.

Can Medicare pay 99374 separately?

No. Medicare assigns status B: payment is bundled into payment for other services, and 99374 is never paid separately.

How are the minutes counted?

Select the code using the total physician supervision time during the calendar month. The 15–29-minute range is reported with 99374, rather than as separate units for individual tasks.

What should the record support?

The record should substantiate the physician’s home health supervision work during the month and the time supporting the 15–29-minute range.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
