Aetna modified CPB 0116 for frenectomy and frenotomy procedures covering ankyloglossia, effective September 26, 2025. Here's what billing teams need to do.
Aetna, a CVS Health company, updated its frenectomy coverage policy under CPB 0116 Aetna system, covering CPT codes 40806, 40819, 41010, 41115, and 41520, along with HCPCS dental codes D7960, D7961, and D7962. The policy governs medical necessity criteria for lingual and labial frenectomy, frenotomy, and frenuloplasty when ankyloglossia is the documented diagnosis. If your practice bills these procedures to Aetna—whether in a physician office, oral surgery, or pediatric setting—this update applies to you now.

Aetna Frenectomy Coverage Criteria and Medical Necessity Requirements 2025
Aetna's coverage policy under CPB 0116 is stricter than some billers expect. Coverage isn't automatic just because ankyloglossia (Q38.1) is present on the claim.
Aetna considers lingual or labial frenectomy, frenotomy, or frenuloplasty medically necessary for ankyloglossia in two specific clinical scenarios. First: newborn feeding difficulties, documented with ICD-10 codes P92.1 through P92.9. Second: childhood articulation problems. No other indications meet Aetna's medical necessity threshold for these procedures.
That means the clinical documentation has to match the code pairing tightly. Q38.1 alone doesn't get you there. Your chart notes need to clearly establish feeding failure in an infant or a documented articulation disorder in a child. If the documentation doesn't show that, Aetna has grounds for a claim denial.
Prior authorization requirements aren't explicitly detailed in CPB 0116, but that doesn't mean prior auth isn't required under the member's specific plan. Check each patient's plan documents before scheduling. Frenectomy billing without a prior auth check is a common revenue cycle gap—don't let it become yours.
Reimbursement for these procedures runs through both medical and dental benefit paths. CPT codes 40806, 40819, 41010, 41115, and 41520 route through the medical benefit. HCPCS dental codes D7960, D7961, and D7962 route through the dental benefit. You need to know which benefit applies before you submit—and some patients have Aetna medical but not Aetna dental, or vice versa.
Aetna Frenectomy Exclusions and Non-Covered Indications
One exclusion stands out. CPT 41115—excision of lingual frenum (frenectomy)—is explicitly not covered when performed using atmospheric plasma (voltaic arc dermabrasion). If your surgeon uses that technology, don't expect coverage under 41115 regardless of diagnosis.
The broader exclusion pattern is equally important. Aetna doesn't recognize dental clenching (F45.8 or G47.63), myofascial tension (M79.18), mouth breathing (R06.5), or snoring (R06.83) as standalone covered indications for these frenectomy procedures. Those ICD-10 codes appear in the policy's diagnosis code list, but their presence doesn't mean Aetna considers the procedure medically necessary for those conditions.
The real issue here: some practices are billing frenectomies with broader functional diagnoses—airway, sleep, or myofascial—and expecting Aetna to cover them. CPB 0116 doesn't support that. Stick to Q38.1 paired with P92.x or documented articulation disorder if you want claims to pass.
If your billing team is seeing denials for these procedures under diagnoses like R06.5 or G47.63, that's not a coding error—it's a policy mismatch. Stop submitting those claims to Aetna under this coverage policy and counsel your clinical team accordingly.
Coverage Indications at a Glance

| Labial frenum with documented clinical indication | Covered | Q38.1, CPT 40806, 40819 | Same medical necessity criteria apply |
| Dental clenching (somatoform or bruxism) | Not Covered | F45.8, G47.63 | Not a recognized indication under CPB 0116 |
| Myofascial tension | Not Covered | M79.18 | Not a recognized indication under CPB 0116 |
| Mouth breathing | Not Covered | R06.5 | Not a recognized indication under CPB 0116 |

Aetna Frenectomy Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your active Aetna claims for CPT 41010, 41115, and 41520 before submitting anything dated after September 26, 2025. Confirm every claim pairs Q38.1 with either a P92.x feeding code or documented articulation diagnosis. Claims missing that pairing are denial candidates. |
| 2 | Update your charge capture templates to flag CPT 41115 when atmospheric plasma or voltaic arc dermabrasion is the documented surgical method. That combination is a hard exclusion under CPB 0116. Flag it at charge entry, not at denial review. |
| 3 | Route claims correctly by benefit type. Use CPT 40806, 40819, 41010, 41115, or 41520 when billing through the medical benefit. Use D7960, D7961, or D7962 when billing through the dental benefit. Submitting a dental code to the medical benefit—or the reverse—generates an automatic claim denial regardless of medical necessity documentation. |
| 4 | Check prior authorization requirements at the plan level for each patient. CPB 0116 sets coverage criteria, but individual Aetna plan documents control prior auth requirements. A patient on a fully insured Aetna HMO may have very different prior auth rules than a patient on a self-funded Aetna ASO plan. Don't assume prior auth isn't needed just because CPB 0116 doesn't mention it. |
| 5 | Counsel your clinical team on documentation standards for newborn feeding difficulties. The ICD-10 codes P92.1 through P92.9 cover a range of newborn feeding problems—from regurgitation (P92.1) to underfeeding (P92.3) to vomiting (P92.6). Be specific. A generic note saying "difficulty feeding" without a specific P92.x code leaves money at risk. Match the code to the documented clinical finding. |
| 6 | If your practice markets frenectomy for airway, sleep, or functional tongue-tie indications beyond ankyloglossia, talk to your compliance officer before the effective date. Billing those services to Aetna under CPB 0116 using diagnoses like R06.5 or G47.63 without a covered indication is a payer billing guidelines mismatch. That creates denial exposure and potentially audit risk. |

One note on the ICD-10 table: Aetna listing these non-covered diagnoses in CPB 0116 isn't an accident. It's a signal that Aetna has seen these codes submitted with frenectomy claims and is explicitly excluding them. If your team has been pairing those codes with frenectomy procedures and getting paid, expect that to change now that the policy has been modified.
