Summary & Overview
CPT 40806: Incision of Labial Frenum
CPT code 40806 represents an incision of the labial frenum without removal, a minor oral soft-tissue surgical procedure used to release a tight frenum and adjacent tissues. Nationally, this code is relevant to pediatric and adult oral surgery, dental-oral medicine, and otolaryngology practices where frenum-related functional or orthodontic concerns arise. It affects coding, billing, and coverage determination for outpatient and office-based services.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code denotes clinically, typical service and site-of-service settings, common modifiers and billing considerations, and where to look for coverage variations across major payers. The summary also highlights typical clinical contexts for use, such as freeing a restrictive frenum that limits lip mobility or interferes with orthodontic treatment.
This publication provides national-level benchmarks and policy context relevant to billing and coverage, as well as practical coding-related information for claims and documentation. Data not available in the input will be noted where applicable, and the report avoids state-specific guidance to remain broadly applicable.
Billing Code Overview
CPT code 40806 describes an incision of the labial frenum, the small tag of tissue in the center of the upper or lower lip that attaches the lip to the gums. The procedure involves incising the frenum without removing it, typically to release a tight frenum and adjacent tissues.
-
Service type: Minor soft-tissue surgical procedure of the oral mucosa
-
Typical site of service: Office, ambulatory surgical center, or outpatient oral surgery setting
Clinical & Coding Specifications
Clinical Context
A typical patient is a pediatric or adult outpatient presenting with a symptomatic tight labial frenum causing restricted lip mobility, gingival recession, gap between the upper central incisors (diastema), or interference with prosthetic appliance fit. The patient history includes localized tugging of the lip on the gingiva, speech articulation concerns, feeding difficulty in an infant, or recurrent gingival inflammation adjacent to the frenum. Examination documents a short, fibrous frenum with a high attachment to the alveolar mucosa or gingival margin. Treatment planning determines that a simple frenum incision without removal (frenulotomy) is appropriate.
Workflow steps: initial evaluation by a general dentist, pediatric dentist, oral and maxillofacial surgeon, or otolaryngologist; informed consent and explanation of procedure and risks; local anesthesia (topical and/or infiltration); use of scalpel or laser to incise the frenum tissue without excision; hemostasis and placement of simple sutures if needed; post-procedure instructions for wound care and activity restrictions; follow-up visit to assess healing and evaluate need for additional interventions (e.g., frenectomy, orthodontic referral). Typical duration is brief and may be performed in a dental office, ambulatory surgical center, or outpatient clinic setting depending on patient age, cooperation, comorbidities, and anesthesia needs.
