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

What 99421 covers

99421 covers a patient-initiated online evaluation and management service for an established patient. A physician or other qualified health care professional may review the patient’s secure portal message, assess the concern, review relevant records, make a management plan, and communicate recommendations or orders electronically. The service is asynchronous; it is not a scheduled video or telephone visit.

Select this level when the clinician’s cumulative time on the online evaluation and management work is 5–10 minutes during the seven-day period. Count the work across the episode rather than reporting separately for each message. Documentation should show the patient’s concern, the clinician’s assessment and management, the communication, and the total time. When the same problem leads to an in-person or other E/M service during the applicable period, the online work is generally included in that E/M service rather than reported separately.
