Summary & Overview
CPT 28636: Metatarsophalangeal Joint Dislocation Treatment with Fixation
CPT code 28636 denotes open treatment of a metatarsophalangeal joint dislocation with percutaneous fixation using screws and pins, including manipulation to reduce the dislocation. This operative code is used for surgical stabilization of displaced joints between the metatarsal and phalanx in the foot and is relevant to orthopedics and podiatry services nationwide. It matters nationally because it represents a definitive surgical intervention with implications for hospital and ambulatory surgery billing, device usage, and post‑operative care pathways.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, service setting expectations (hospital operating room or ambulatory surgical center), and common billing considerations tied to surgical fixation of toe joints. The publication outlines typical service line placement, expected use cases for this code, and benchmarking elements such as utilization patterns and payment structure where available. It also summarizes policy and coding considerations that affect claim processing and documentation requirements. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 28636 describes open treatment of a metatarsophalangeal joint dislocation with percutaneous fixation using screws and pins and includes manipulation (reduction) of the dislocated bones. The procedure addresses abnormal separation between a metatarsal bone and a phalanx in the foot by realigning the joint and stabilizing it with hardware inserted through the skin.
Service type: Surgical — open treatment with percutaneous fixation and manipulation
Typical site of service: Hospital operating room or ambulatory surgical center, with the procedure performed on the foot (metatarsophalangeal joint).
Clinical & Coding Specifications
Clinical Context
A typical patient is a 28-year-old recreational soccer player presenting to the emergency department with acute pain, deformity, and inability to bear weight after an inversion injury to the forefoot. Physical exam demonstrates visible dorsal displacement of the second metatarsophalangeal joint with swelling and tenderness. Plain radiographs confirm a dislocation of the metatarsophalangeal joint, sometimes with an associated small avulsion fracture. After informed consent, the patient is taken to the operating room or procedure suite for closed reduction under regional or general anesthesia. The provider performs manipulation to reduce the dislocation followed by percutaneous fixation with screws and/or K-wires to maintain reduction when instability or comminution is present. Post-procedure workflow includes imaging confirmation of reduction, application of a postoperative dressing or cast, pain management, and instructions for non-weightbearing with follow-up in clinic for pin removal and monitoring for infection or hardware complications. Typical sites of service are the emergency department, operating room, ambulatory surgery center, or procedure suite within an orthopedic clinic depending on urgency and anesthesia needs.
