What 41520 covers

CPT 41520 describes surgical reconstruction of the lingual frenulum, the fold of tissue beneath the tongue. It is commonly used for ankyloglossia when restricted tongue movement calls for frenuloplasty rather than simple division or removal of the frenulum. Otolaryngologists and oral and maxillofacial surgeons may perform the procedure in an office or operating-room setting, depending on the patient and the planned repair.

Select the code when the operative work reconstructs or lengthens the tongue fold; document the functional restriction, relevant anatomy, and repair performed. The code has 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% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

41520 billing questions

How does 41520 differ from lingual frenulum excision?

Use 41520 for reconstruction or lengthening of the tongue fold. CPT 41115 describes excision of the lingual frenulum; choose based on the operative work documented.

What documentation supports 41520?

Document the restricted tongue movement and relevant frenulum anatomy, along with the reconstructive technique performed. The note should make clear why the service was reconstruction rather than simple division or excision.

Is modifier 50 appropriate for this procedure?

No. The anatomy and descriptor make bilateral adjustment inappropriate.

How does the 90-day global period affect postoperative billing?

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

Can an assistant or another surgeon be reported?

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

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.
