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

What 99151 covers

This code describes moderate sedation delivered by the physician or qualified health professional who also performs the diagnostic or therapeutic procedure. An independent trained observer assists with monitoring the patient’s consciousness and physiologic status. A typical situation is an image-guided procedure, such as a biopsy, when the proceduralist provides the sedation. The patient must be younger than five years.

Report this code for the initial 15-minute intra-service interval. Documentation should identify the patient’s age, the supported procedure, the clinician providing both services, the observer, and sedation start and stop times. Use a different code when another physician or qualified health professional provides the sedation. Additional intra-service time is reported with 99153 when supported by the service and documentation. Medicare fee-schedule valuation is shown separately from this description.
