What 41016 covers

Code 41016 describes surgical drainage reached through the mouth for an infection in the sublingual, submandibular, or submental space. Oral and maxillofacial surgeons and otolaryngologists commonly perform it in an operating room when a deep infection requires operative access, rather than drainage of a superficial oral lesion. The documented approach must be intraoral and the involved space must support selection of this code.

Record the affected space, incision route, findings, and drainage performed. The 90-day global period includes the preoperative visit on the day before surgery and related postoperative care for 90 days. 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% reduction. Modifier 50 is not appropriate for this anatomy. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

41016 billing questions

How is 41016 distinguished from 41017?

41016 is for drainage through an intraoral approach. Use 41017 when the surgeon reaches the sublingual, submandibular, or submental space externally.

Does the note need to identify the space and approach?

Yes. Document the involved anatomic space and that drainage was performed through an intraoral incision.

Can modifier 50 be reported?

No. The anatomy is represented by a single procedure code, not a bilateral modifier 50 claim.

How does the 90-day global period affect follow-up billing?

The day-before preoperative visit and related postoperative care for 90 days are included in the global period.

Can an assistant surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.

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.
