CPT code 41115 – Frenulectomy of the tongue

Key takeaways

CPT code 41115 is excision of the lingual frenum, so the operative note must show the band was removed, not just released.

A frenotomy (incision only) is CPT 41010, a lip or cheek frenum is 40819, and a Z-plasty revision is 41520.

Ankyloglossia (Q38.1) is the core diagnosis, and it needs documented feeding or speech impairment behind it.

K13.0 is a lip disease code, so it supports 40819 for a labial frenum rather than 41115.

Some Medicare contractors treat frenectomy as dental or cosmetic, so check the local coverage determination before surgery.

CPT code 41115 covers removal of the lingual frenum

CPT code 41115 is the American Medical Association’s code for excision of lingual frenum (frenectomy). The surgeon removes the lingual frenulum, the band of tissue that tethers the underside of the tongue to the floor of the mouth. The wound is then usually closed with sutures or a mucosal advancement.

That removal is what defines the code. A frenotomy only cuts the band, and it’s billed as 41010. Clinical notes use frenulectomy, frenectomy and frenuloplasty loosely, so confirm in the operative note that tissue came out before you assign 41115.

In the AMA’s CPT code set, 41115 sits in the 41000-41599 tongue and floor of mouth subsection. Its neighbors there include 41010 and the tongue lesion codes 41110-41114.

Medical necessity for 41115 rests on function, not anatomy

Ankyloglossia, or tongue-tie, is the usual reason a surgeon performs 41115. The frenum attaches too far forward or is too short, so the tongue can’t move freely. Payers want to see what that restriction does to the patient, not just that it exists.

• Ankyloglossia with feeding impairment: documented lactation failure, poor latch, or inadequate weight gain in infants
• Ankyloglossia with speech impairment: phonological or articulation delay assessed by a speech-language pathologist
• Restricted frenum causing periodontal tension: tissue pull creating gingival recession or diastema
• Functional limitation in adults: trouble with oral hygiene, dental prosthetics, or swallowing that conservative measures haven’t resolved

Payers also expect proof that conservative treatment came first. Lactation consultant records, a speech therapy evaluation, or a documented trial of stretching exercises all strengthen the case.

41115 vs 41010 comes down to whether tissue was removed

CPT 41010 is incision of the lingual frenum (frenotomy), while CPT 41115 is excision. An incision releases the frenum, and an excision takes it out. Mixing the two up is one of the most frequent errors on these claims.

Here’s a quick test you can run on any operative note. A scissor snip or laser release with no specimen and no sutures is almost certainly 41010. Excised tissue plus a closed wound points to 41115.

The diagram below adds the two neighboring codes that get confused with both.

The diagnosis code has to match the frenum you treated

The ICD-10-CM code matters as much as the CPT code. Many payers auto-deny 41115 when the diagnosis falls outside the covered indications in their medical policy.

The K13.0 row catches people out. When the chart describes a lip frenum, the procedure is 40819, and the claim should carry that code instead of 41115.

Before submitting, check which diagnoses each payer’s policy accepts. BCBSM’s policy 80226 and Aetna’s Dental Clinical Policy Bulletin both list the ICD-10 codes they cover for frenum surgery.

Medicare coverage for 41115 depends on your contractor

Medicare coverage for CPT code 41115 isn’t automatic. Some Medicare Administrative Contractors (MACs) treat frenectomy as a non-covered dental or cosmetic service. Without a Local Coverage Determination (LCD) setting medical necessity criteria, the claim may fall outside Part B.

Before you submit, check the CMS Physician Fee Schedule search tool and your MAC’s LCD database. If no active LCD covers the procedure in the patient’s state, expect a denial. When coverage is in doubt, give the patient an Advance Beneficiary Notice (ABN) before surgery.

• Facility rate: lower than non-facility, and applies when the procedure is done in an ASC or hospital outpatient department
• Non-facility rate: applies when the procedure is done in a physician office or freestanding outpatient setting
• Global period: 10 days (verify against current CMS data before billing), with routine follow-up bundled
• ABN requirement: issue it before the procedure if Medicare coverage is uncertain

Run an eligibility check before the procedure date as well. A coverage problem costs far less to find at scheduling than on the remittance.

Five modifiers cover most 41115 scenarios

Modifier mistakes are a frequent cause of 41115 denials. Watch which line each one belongs on, because -25 never goes on 41115 itself.

Check the National Correct Coding Initiative (NCCI) edit table before billing 41115 with another oral surgery or E&M code on the same date. CMS updates those edits every quarter.

Commercial payers each publish their own frenum policy

Commercial payer rules carry more weight on frenum procedures than on most surgical codes. Several major plans publish written policies on when they’ll pay for frenectomy, and the criteria differ.

• Highmark BCBS: Highmark publishes a frenum medical policy. Confirm the current version in the provider portal.
• BCBSM (Policy 80226): covers frenum surgery when functional impairment establishes medical necessity. It lists Q38.1 among covered ICD-10 codes, and prior authorization may apply depending on plan type.
• Aetna (Dental Clinical Policy Bulletin DCPB011): covers frenectomy as medically necessary when ankyloglossia causes documented feeding or speech impairment. Whether it falls under the dental or medical benefit depends on the plan.
• Bridgespan Health: publishes a separate frenotomy reimbursement policy, with age restrictions and documentation requirements.

Pull the current policy from the payer’s provider portal before you submit. Bulletins change annually, and so can prior authorization rules between plan years. Where a plan routes frenum surgery through the dental benefit, the claim usually goes on the ADA dental claim form rather than the CMS-1500.

How a 41115 claim moves from consult to payment

Most 41115 problems start well before anyone picks a code. Here’s the path a clean claim takes, and where each step tends to break.

1. Scheduling: confirm whether the plan pays under the medical or dental benefit. Check eligibility and get prior authorization if the policy requires it.
2. Surgery: the operative note records the technique, the tissue excised, and the closure method. Without those details, the claim reads like a frenotomy.
3. Coding: assign 41115 with Q38.1 and the functional diagnosis, such as R47.89 or P92.5. Add modifiers only to the lines that need them.
4. Submission: the claim goes to the payer, usually through a clearinghouse that runs its own edits first. Rejections at this stage are about format, not coverage.
5. Adjudication: the payer pays or denies, and the remittance shows why. Routine visits in the 10-day global period are bundled, so they aren’t billed separately.

Before you submit: The 41115 documentation checklist

Documentation is what separates a paid 41115 claim from an audit finding. Together, the pre-op chart and the operative note must show why surgery was needed, what was done, and that simpler care came first.

A clean claim submission routine catches the missing details auditors look for. Run each 41115 chart through this list before it goes out.

• Pre-operative assessment: degree of lingual restriction, graded with a validated tool (Hazelbaker, Kotlow, or equivalent), plus a recorded tongue-lift or tongue-to-floor measurement
• Functional impairment: a speech-language pathology report, a lactation consultant note, or a physician’s description of the specific deficit
• Conservative treatment failure: a record of stretching exercises, lactation support, or speech therapy trials that didn’t work
• Operative note: technique (scissors, laser, electrocautery), tissue excised and approximate size, closure method and suture type, blood loss, and post-op findings
• ICD-10 alignment: a diagnosis that matches the documented indication (Q38.1 for ankyloglossia, not a nonspecific code)
• Pathology: the pathology report if a specimen was sent, or a note that tissue was discarded per practice protocol

Consistent medical billing compliance standards across all your surgical codes also limit exposure when a payer audits frenum claims in bulk.

Where 41115 claims get denied, and how to prevent it

Denials on 41115 follow a predictable pattern. Most can be prevented with better documentation and workflow, which beats working appeals afterward.

Structured denial management workflows that track reason codes at the claim level surface the patterns fastest. If a remittance code is unfamiliar, our guide to medical billing denial codes explains what each one means.

41115 payment is built from three RVUs and your locality

Medicare pays CPT code 41115 through the Medicare Physician Fee Schedule (MPFS) relative value unit (RVU) method. There are three RVU components: work, practice expense, and malpractice. Each is adjusted for geography, then multiplied by the annual conversion factor CMS publishes.

Use the FastRVU 2026 RVU lookup tool and the AAPC Codify CPT lookup to pull current RVU values for your locality. Rates change every January 1. The table below shows how the rate is built, not what any payer will pay.

Commercial payer rates for CPT 41115 commonly exceed Medicare rates, varying by contract. If you use a superbill for oral surgery encounters, confirm that 41115 carries the correct global period flag before it generates the claim.

How Pabau supports cleaner 41115 claim submission

In many oral surgery and ENT practices, a 41115 claim crosses several systems. The schedule lives in one tool and the op note in another, and then someone keys the claim into a clearinghouse portal. Every re-entry is a chance to drop an authorization number or mistype a code.

Pabau, the practice management platform we build, keeps those steps in one patient record. Its claims management software pre-fills the claim from that record and checks required fields before the claim can be sent.

Through the Claim.MD clearinghouse, Pabau runs real-time eligibility checks, submits the claim, and tracks its status. Remittances post back to the same record, so your team can spot a coverage problem before surgery day instead of after.

Submit cleaner frenum surgery claims

Pabau checks eligibility in real time and submits CPT claims through the Claim.MD clearinghouse, built from the patient record. Coverage problems surface before surgery, not on the remittance.

Conclusion

Treat 41115 as a documentation code first and a surgical code second. The procedure is simple. Payment depends on what the chart can prove: a lingual frenum, removed tissue, and a functional problem that conservative care didn’t fix.

If your operative note template doesn’t prompt for the tissue excised and the closure method, fix that first. It’s the cheapest change you can make, and it stops future claims from being recoded as 41010.
