Summary & Overview
CPT 28665: Closed Reduction of Toe Interphalangeal Joint Dislocation
CPT code 28665 represents the closed reduction of an interphalangeal joint dislocation in a toe performed under anesthesia. This code captures a common urgent orthopedic procedure to restore joint alignment without open surgery. Nationally, accurate coding of these procedures matters for appropriate payment, quality measurement, and procedure tracking across ambulatory surgical centers and hospital outpatient settings. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise clinical context for the procedure, typical sites of service, and the common billing modifiers associated with anesthesia and surgical services. The publication highlights benchmark metrics and coverage considerations used by major commercial insurers and Medicare, outlines typical service-line placement for surgery and orthopedics, and summarizes coding nuances relevant to closed reductions of toe interphalangeal joints. Data not provided in the input — such as specific payer reimbursement rates, associated ICD-10 diagnoses, and related codes — are noted as unavailable. The material is intended for coding professionals, billing managers, and clinical leaders seeking a national overview of CPT code 28665 and its operational context.
Billing Code Overview
CPT code 28665 describes the closed treatment of an interphalangeal joint dislocation of the toe performed under anesthesia. The procedure involves manipulation to return an interphalangeal joint (a joint between two phalanges of a toe) to its normal alignment without an open surgical incision.
-
Service type: Closed joint reduction procedure of a toe interphalangeal joint performed with anesthesia
-
Typical site of service: Ambulatory surgical center or hospital operating room for procedures performed under anesthesia; could also occur in an outpatient procedure suite when anesthesia services are available
Clinical & Coding Specifications
Clinical Context
A 28-year-old recreational soccer player presents to the emergency department after an acute inversion injury to the foot during play. The patient reports immediate pain, visible deformity of the lesser toe, and inability to actively flex the toe. Physical exam demonstrates swelling, tenderness localized to the interphalangeal joint of the second toe with obvious abnormal alignment consistent with a dislocation. Neurovascular status is intact. Plain radiographs of the toe confirm an isolated interphalangeal joint dislocation without associated fracture.
The provider performs closed reduction of the toe interphalangeal joint under regional or local anesthesia in the ED procedure room. The workflow includes consent, analgesia or regional block administration, closed manipulation to reduce the dislocation, post-reduction radiographs to confirm alignment, application of buddy taping or a protective dressing/splint, and discharge instructions with short-term follow-up with an orthopaedic foot and ankle clinic. Documentation includes pre- and post-reduction neurovascular status, anesthesia used, method of reduction, imaging findings, and aftercare plan.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when an E/M visit is provided on the same day and is distinct from the reduction procedure (note: was not in provided modifier list; must not be listed if strictly following list). |
