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

What 42505 covers

This service involves complex reconstruction of a salivary duct after an earlier procedure, injury, or disease has left the duct damaged or scarred. The surgeon restores duct continuity or function through a secondary repair; the work may involve reconstructing or repositioning the duct. Otolaryngologists and oral and maxillofacial surgeons typically perform it in an operating room, including for parotid or other major salivary duct problems.

Choose this code when the operative work is a complicated secondary repair, rather than a simple primary duct procedure. Document the reason for secondary reconstruction, the condition of the duct, and the repair performed. The day-before preoperative visit and related postoperative care through day 90 are included in the global period. When other 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. Medicare does not pay an assistant at surgery for this service under the statutory restriction; co-surgeons and team surgery are not permitted.
