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

What 69603 covers

An otolaryngologist or otologist reports this service when revising a previously operated mastoid and the completed procedure results in a radical mastoidectomy. It is associated with complex ear disease, such as persistent or recurrent cholesteatoma, when the surgeon must revise the mastoid cavity and establish the radical surgical result. The operative report should describe the prior mastoid surgery, the work performed, and the resulting anatomy and extent of the revision.

Select this code based on the final operative result, not the diagnosis alone; a revision ending in a different mastoidectomy result belongs to a different code in the revision series. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
