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

What 42227 covers

This operation lengthens the palate while repositioning palatal muscle, generally to improve velopharyngeal function when the palate is too short or does not close adequately. It may be performed as secondary surgery for a patient with a history of cleft palate repair. Plastic and craniofacial surgeons, oral and maxillofacial surgeons, or otolaryngologists may perform the procedure in an operating room.

Report 42227 when the operative record supports palate lengthening with muscle repositioning, rather than a different palatal repair or lengthening procedure. Document the indication, prior palate history when relevant, and the specific surgical work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral adjustment is inappropriate for this palatal procedure. An assistant at surgery may be paid; co-surgeon and team-surgery billing are not permitted.
