Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99416 covers

99416 represents additional time spent by clinical staff extending an office or outpatient evaluation and management service. It is used after the initial prolonged clinical staff service represented by 99415, when staff continue care under a physician’s or other qualified health care professional’s supervision. The work may occur in an office or outpatient setting; the claim must connect the staff time to the qualifying E/M encounter rather than to unrelated administrative work.

Report 99416 only with its required primary service, including 99415 for the initial prolonged staff service. Document the staff members involved, the supervised clinical work, and the additional time attributable to the encounter so the units billed are supported. CMS classifies this code as technical-component-only, with interpretation covered by a separate code. Payment is made within the primary procedure’s global period, so the add-on is not billed as a standalone service.
