Summary & Overview
CPT 27767: Posterior Malleolus Fracture Stabilization
CPT code 27767 represents a targeted procedure for stabilization of nondisplaced or hairline fractures of the posterior malleolus. The intervention aims to keep the fracture aligned, prevent displacement during the healing period, and provide pain relief. This code is clinically important for appropriate surgical and nonsurgical management of ankle fractures and for ensuring accurate billing and coverage determinations across national payers.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides an overview of clinical context, typical sites of service, and payer coverage considerations relevant to surgical and outpatient settings.
Readers will learn the clinical scope of CPT code 27767, how it is used to document stabilization of posterior malleolus fractures, and the typical care settings where the procedure is performed. The summary outlines what to expect in benchmarks and policy discussions at a national level, and highlights areas where payers commonly focus on medical necessity and documentation. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 42-year-old male presents to the orthopedic clinic 4 days after twisting his ankle while playing soccer. He reports persistent posterolateral ankle pain and difficulties weightbearing. Plain radiographs demonstrate a nondisplaced posterior malleolar (posterior tibial lip) fracture without articular step-off; no manipulation is required. The provider elects to apply a posterior splint or short leg cast to maintain alignment and provide pain control while the fracture heals. The clinical workflow includes initial evaluation with history and physical, radiographic confirmation, informed consent for nonoperative immobilization, application of immobilization (posterior splint or cast), instructions for weightbearing status and wound/skin care, scheduling of follow-up radiographs at 1 and 2 weeks to assess stability, and possible transition to definitive casting or removable boot based on healing and symptoms. Coordination with physical therapy for progressive range of motion and strengthening occurs after radiographic healing. Documentation includes fracture description, stability assessment, immobilization type, laterality, and follow-up plan.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | Use when work required is substantially greater than typical for immobilization of a nondisplaced posterior malleolus (e.g., difficult application due to severe swelling or multiple attempts). |
