Summary & Overview
CPT 28666: Percutaneous Fixation for Toe Interphalangeal Joint Dislocation
CPT code 28666 denotes surgical management of an interphalangeal joint dislocation of a toe using percutaneous screws or pins with manipulation (closed reduction). This code captures a focused orthopaedic procedure to realign and stabilize the phalanges when an interphalangeal joint is abnormally separated. Nationally, accurate coding of 28666 matters for procedural tracking, quality measurement of acute foot and toe trauma care, and reimbursement alignment for ambulatory and inpatient surgical settings.
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, common billing considerations, and the payer landscape relevant to this service. The publication provides benchmarks and coding guidance trends where available, summaries of typical sites of service, and notes on common modifier usage for procedural variations. Additionally, the report outlines areas where input data were not provided and flags items that typically appear in payer policy reviews, such as diagnosis linkage and surgical documentation requirements.
This summary is intended for coders, practice managers, and policy analysts seeking a national overview of CPT code 28666 and its role in coding and payment for toe interphalangeal joint dislocation repair.
Billing Code Overview
CPT code 28666 describes surgical treatment of an interphalangeal joint dislocation of a toe using percutaneous fixation with screws and/or pins combined with manipulation and reduction of the dislocated phalanges. The procedure addresses abnormal separation of the joint between two phalanges of a toe and restores alignment by adjusting the bones and securing them through the skin with internal fixation devices.
-
Service type: Surgical procedure — percutaneous fixation and closed manipulation (reduction) of an interphalangeal joint of the toe

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient presents to the emergency department after stubbing the lesser toe during a soccer match. Physical exam and radiographs demonstrate a dorsal dislocation of the proximal interphalangeal joint of the second toe with associated instability. The orthopedic surgeon performs closed manipulation to reduce the interphalangeal joint, achieves acceptable alignment, and then percutaneous fixation with K-wires (pins) and a small screw placed through the skin to maintain reduction. The procedure is performed in the operating room under regional or general anesthesia. Post-procedure, the surgical site is dressed, pin care instructions are provided, and follow-up is arranged in clinic for radiographic confirmation of healing and eventual pin removal. Typical workflow includes preoperative consent and imaging, intraoperative reduction and percutaneous fixation, immediate postoperative dressing and analgesia, and scheduled outpatient follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical (document reasons). |
23 | Unusual anesthesia | Use when procedure performed under general anesthesia for unusual circumstances. |
