CPT code 25535 represents closed treatment (manipulation without incision) of a fracture of the shaft of the ulna, a common forearm injury. This code captures non-operative fracture management where alignment is achieved by manipulation rather than open surgical exposure. Nationally, accurate coding for closed reductions affects clinical documentation, billing consistency, and claims adjudication for acute musculoskeletal injuries across emergency, urgent care, and outpatient orthopedic settings.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage patterns, common billing modifiers used with closed fracture care, and benchmarks for service settings where 25535 is typically billed. The publication also provides clinical context about the procedure type, typical sites of service, and the implications for coding accuracy and claims processing.

The content is designed to inform coding professionals, billing managers, and clinicians about where 25535 fits in procedural coding, common operational considerations for non-operative ulna shaft fracture management, and the kinds of policy and reimbursement issues to monitor at a national level.
