CPT code 26418 denotes repair of an extensor tendon in a finger without use of a graft, applicable to both early (primary) repairs and delayed (secondary) repairs. This surgical code is clinically important because extensor tendon injuries can impair hand function and require timely operative management to restore extension and prevent long-term disability. Nationwide, coverage and payment policies for tendon repair affect access to timely surgical care, rehabilitation planning, and post-operative functional outcomes.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service, typical sites of care, common billing modifiers and coding context, and the payer mix referenced in national analyses. The publication outlines benchmarks and payment considerations, summarizes relevant policy updates that influence preauthorization and site-of-service determinations, and provides clinical context on distinctions between primary and secondary repair approaches.

This summary is intended for revenue cycle managers, surgical providers, and coding professionals seeking a focused briefing on CPT code 26418, its clinical role in hand surgery, and the payer landscape that commonly governs coverage and reimbursement for extensor tendon repair.
