Coverage Criteria and Evidence Summary
Medical Necessity Criteria
Covered when ANY of the following clinically relevant conditions are present and documented:
Source: Aetna medical necessity statement (Policy).
Experimental / Investigational
Considered experimental/investigational (Not covered) when performed for any of the following:
Supported by policy statement and systematic review conclusions indicating insufficient evidence of effectiveness.
Evidence-based coverage considerations
Clinical evidence and practice considerations summarized from the literature:
Sources include Campbell systematic review, Suter and Bornstein review, Zaghi cohort, Garrido review, and Bhandarkar retrospective study.
Cited trial and review outcomes; safety and methodological limitations noted.
Recommendation reflects interpretation of available evidence and practice considerations.
Aetna considers prophylactic frenotomy, frenectomy, or frenuloplasty to promote speech development experimental and investigational because the effectiveness of this approach has not been established. The policy therefore excludes procedures performed solely for prophylactic speech promotion and lingual frenuloplasty performed with myofunctional therapy for indications such as dental clenching, mouth breathing, myofascial tension, and snoring as these uses lack established effectiveness and may be denied.
When evaluating requests, clinical documentation should demonstrate a relevant, symptomatic indication (for example, newborn feeding difficulty or childhood articulation problems) rather than a prophylactic intent to optimize speech development; absence of such documentation supports a determination of investigational/noncovered.
Isolated labial frenectomy lacks sufficient evidence to conclude that it contributes to improvement in breastfeeding. Available studies include very few infants who had only a labial frenectomy, so the independent effect of labial frenectomy on feeding outcomes cannot be determined.
Labial frenectomy is most commonly considered in the context of dental or anatomic issues (for example, midline diastema or eruption abnormalities); if no functional disorder is present, a conservative approach with observation and follow-up is recommended.
Procedures performed prophylactically to promote speech development are considered investigational and therefore not medically necessary. Systematic reviews and available studies do not provide sufficient evidence of benefit for routine prophylactic release of the frenulum to improve later speech outcomes.
Providers should document specific clinical signs or symptoms (for example, impaired tongue mobility with demonstrable impact on feeding or articulation) when seeking coverage; interventions performed solely for anticipated future speech benefit are subject to denial as experimental.
Routine use of topical benzocaine for analgesia prior to lingual frenotomy in term infants is discouraged. A randomized trial and an RCT comparing topical anesthetics found no significant reduction in crying time or validated pain scores with topical benzocaine or tetracaine, and the FDA has warned about the rare but potentially fatal risk of methemoglobinemia with benzocaine in infants.
Because topical anesthetics have not demonstrated clear benefit for procedural pain control in this setting and carry safety concerns, clinicians should avoid routine benzocaine use for lingual frenotomy in term infants and consider alternative analgesic strategies supported by current guidance.

Provider Requirements, Prior Authorization, and Billing Notes
Coding must match covered indication
Submit CPT, HCPCS/Dental, and ICD-10 codes that correspond to the covered indication on the claim and in any prior authorization request; coding lists in the policy identify codes covered when selection criteria are met and codes not covered for listed indications.
- Covered CPT codes (if selection criteria met): 40806, 40819, 41010, 41115, 41520
- Covered HCPCS / Dental codes (if selection criteria met): D7960, D7961, D7962
- Covered ICD-10 codes (if selection criteria met): P92.01 - P92.9, Q38.1
- ICD-10 codes not covered for indications listed: F45.8, G47.63, M79.18, R06.5, R06.83
Prior authorization requirement — confirm plan rules
Check plan-specific prior authorization requirements and follow the Aetna Clinical Policy Bulletin notes and links for any authorization processes required by the member's benefit plan.
- Refer to the Clinical Policy Bulletin Notes and Review History links for administrative details and plan provisions.
- Ensure any required prior authorization is obtained per the member's benefit plan before performing the procedure.
Prior authorization — no requirements listed here
This policy segment does not specify prior authorization requirements for the procedures themselves; verify authorization requirements with the member's plan because this document portion contains only policy text and administrative links.
- Policy text states no prior authorization requirements are provided in this portion of the policy.
- Use plan-specific resources to determine if prior authorization is required.
Conservative-first approach — document nonoperative trial
When conservative management or observation are appropriate, document the trial of nonoperative measures; surgical options (frenotomy, frenectomy, frenuloplasty) are described as treatments when indicated but no single surgical method is favored.
- Conservative management and observation should be considered prior to surgical intervention.
- If surgery is performed, document rationale for chosen procedure (frenotomy, frenectomy, or frenuloplasty) given limited comparative evidence.
Step therapy — none specified
No step therapy requirements are stated in this portion of the policy.
- The policy explicitly notes that no step therapy requirements are mentioned on these pages.
Clinical indication documentation — support feeding or articulation problems
Document clinical findings that support the medical necessity criteria: newborn feeding difficulties (e.g., feeding problems of newborn codes) or childhood articulation problems when requesting coverage for lingual or labial procedures.
- Include specific feeding or articulation assessment findings in the medical record.
- When using ICD-10 codes for feeding problems or ankyloglossia, ensure documentation ties the diagnosis to the clinical indication for the procedure.
Documentation and policy references — follow CPB links
Follow the Clinical Policy Bulletin Notes, definitions, and review history links provided in the policy for documentation guidance and administrative details relevant to coverage and claims processing.
- Use the policy's supporting definitions and review history when preparing documentation or responding to medical necessity inquiries.
- Consult the Clinical Policy Bulletin Notes link for additional administrative instructions.
Administrative/legal notices — verify plan-specific rules
This segment contains administrative and legal notices and does not itself list new documentation or prior authorization requirements; providers remain responsible for verifying benefit coverage and authorization rules.
- Clinical Policy Bulletins are administrative guidance and may be updated; they do not replace plan-specific benefit determinations.
Denial risk — experimental or prophylactic indications
Procedures performed prophylactically to promote speech development or for indications deemed experimental (for example, lingual frenuloplasty with myofunctional therapy for dental clenching, mouth breathing, myofascial tension, or snoring) may be denied as experimental/investigational.
- Document clinical necessity and avoid using excluded indications as justification for coverage.
- Coverage determinations may deny procedures performed for speech-promotion prophylaxis or other experimental indications listed in the policy.
Policy maintenance note — track review dates
Policy history and review dates are tracked; ensure documentation and practice follow current policy updates because failure to consider policy revisions may affect coverage determinations.
- Last review date: 03/22/2023; Effective date: 01/17/1996; Next review: 01/25/2024.
- Check Review History and Definitions links for updates that may affect prior authorization or coverage decisions.
No specific denial triggers listed in additional information
No additional denial triggers are specified on the policy's additional information pages.
- Additional Information section contains administrative content but does not list denial triggers.
Background and Clinical Context
Ankyloglossia, or tongue-tie, is present when the inferior lingual frenulum attaches to the ventral surface of the tongue in a way that restricts tongue mobility and can interfere with feeding or speech. When tongue mobility is adequate (for example, when the tongue can touch the anterior dentition), speech development is typically normal; significant restriction may impair suckling in infants or articulation in children.
Clinical outcomes after frenotomy, frenectomy, or frenuloplasty vary. Systematic reviews and randomized trials report limited and mixed-quality evidence: some studies show transient improvements in breastfeeding measures and reductions in maternal nipple pain, but evidence for lasting improvement in infant feeding or speech articulation is inconsistent. Patient selection should therefore be individualized, conservative management considered, and families counseled about the uncertain benefits for speech and modest/short-term benefits for breastfeeding.
