Summary & Overview
CPT 28510: Closed Treatment of Toe Phalanx Fracture Without Manipulation
CPT code 28510 represents the closed treatment of a phalanx or phalanges fracture in a toe other than the great toe when no manipulation or adjustment of the fractured bone is performed. This code is used nationally to document and bill for conservative, non-manipulative management of toe fractures, a common injury in emergency, urgent care, and outpatient orthopedic settings. Accurate use of the code affects claims processing, provider billing consistency, and national utilization tracking for minor lower-extremity fracture care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides readers with benchmarks for utilization and reimbursement patterns, clinical context for when the code is appropriate, and an overview of common billing considerations. It also outlines typical sites of service and how this procedure is classified relative to other toe fracture treatments. Data not available in the input will be noted where relevant.
Readers will learn how CPT code 28510 is defined, the clinical situations that align with its use, and the types of settings where the service is delivered. The piece is aimed at billing professionals, provider administrators, and policy analysts who need a concise reference for coding and classification of non-manipulative closed treatment of toe phalanx fractures.

Clinical & Coding Specifications
Clinical Context
A patient (commonly an adult or adolescent) presents to the urgent care clinic, emergency department, or orthopedic clinic after stubbing a toe or sustaining a direct blunt trauma to the foot. The patient reports localized pain, swelling, and difficulty bearing weight. Physical exam shows tenderness over a toe phalanx with possible mild malalignment but without gross displacement. Plain radiographs confirm a nondisplaced or minimally displaced fracture of a phalanx in a toe other than the great toe.
The clinical workflow: the provider reviews imaging, documents the fracture location and stability, and determines that closed treatment without manipulation is appropriate. The procedure consists of immobilization (rigid or soft dressing, buddy taping, or short leg wearing shoe) and provision of analgesia and activity restrictions. Follow-up instructions and a return visit for re-evaluation and repeat radiographs are scheduled as appropriate. The encounter may occur in an outpatient clinic, urgent care center, or emergency department, and may be billed with a procedure code for closed treatment without manipulation of a toe phalanx.
