CPT code 28450 represents the closed treatment of a tarsal bone fracture (excluding talus and calcaneus) without manipulation or adjustment of the fractured bone. This procedural code captures nonopen management of midfoot and rearfoot fractures involving the navicular, cuboid, and cuneiform bones. The code matters nationally because tarsal fractures are managed across inpatient and outpatient settings and generate distinct billing, utilization, and coverage considerations for orthopedics and trauma care.

Key payers in national coverage and reimbursement discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers commonly determine facility and professional payment policies that influence site-of-care choices and claims adjudication for closed tarsal fracture treatments.

Readers will learn the clinical scope of CPT code 28450, the typical service setting and service type, and the payer landscape relevant to claims and coverage. The publication provides benchmarks and policy context for payers named above, outlines common billing modifiers and administrative notes (where available), and summarizes the clinical scenario that maps to this code. Data not available in the input is clearly identified and omitted.
