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.

42509Parotid duct diversion
42509 is a parotid duct diversion procedure. The operative objective is diversion, whereas 42505 represents complicated secondary duct repair.

42505 billing questions

How does this differ from 42500?

Use 42505 for a complicated secondary repair, such as reconstruction of a previously treated or scarred duct. Code 42500 describes a simple primary duct procedure.

Is postoperative care separately reportable?

Related postoperative care through day 90 is included in the global period, along with the day-before preoperative visit.

Can modifier 50 be used?

No. The descriptor and anatomy make modifier 50 inappropriate for this code.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this service under the statutory restriction. Co-surgeons and team surgery are not permitted.

How is this paid with another procedure in the same session?

The highest-valued procedure is paid in full; other procedures in the same session are subject to the standard 50% multiple-procedure reduction.

What documentation supports choosing 42505?

Describe why secondary reconstruction was needed, the duct's condition, and the operative repair. The record should support complicated secondary work rather than a simple primary procedure.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
