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.
