Summary & Overview
CPT 26770: Closed Reduction of Single Interphalangeal Joint Dislocation
CPT code 26770 covers the closed treatment (manual reduction) of a single interphalangeal joint dislocation performed without anesthesia. Nationally, this code documents a common, low-complexity urgent procedure used to realign finger or toe joint dislocations in ambulatory and emergency settings. Accurate coding ensures appropriate clinical documentation and claims processing for brief, office- or ED-based reductions that do not involve open surgery or anesthesia.
Key payers in routine coverage and claims adjudication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when CPT code 26770 applies, common sites of service where the procedure is performed, and how the code differs from operative or anesthesia-associated reductions. The publication provides benchmarks and policy-related considerations relevant to national billing and reimbursement practices, highlights documentation elements that support correct code assignment, and summarizes typical billing scenarios and potential coding pitfalls. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 26770 describes a closed treatment of a single interphalangeal joint dislocation performed with manipulation or adjustment of the dislocated bone without anesthesia. The procedure focuses on reducing a dislocated interphalangeal joint through manual techniques rather than open surgical approaches.
Service type: Closed joint reduction / minor procedure
Typical site of service: Outpatient clinic, urgent care clinic, emergency department, or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A patient presents to an urgent care center or emergency department after a fall while playing sports. The patient reports acute pain, visible deformity, and limited motion of a single finger at an interphalangeal joint. Physical exam demonstrates a displaced fingertip position consistent with a single interphalangeal joint dislocation without open wound. Neurovascular status is intact. A quick point-of-care radiograph confirms joint malalignment without associated fracture requiring open reduction.
The clinician performs a closed reduction by manual manipulation of the dislocated interphalangeal joint without regional or general anesthesia (local/topical analgesia may be used). Post-reduction, the joint is reassessed for stability, neurovascular status, and range of motion. A buddy splint or finger dressing is applied, and the patient is given aftercare instructions including elevation, ice, analgesics, and a follow-up with hand specialist or primary care within 5–10 days. Documentation includes pre- and post-reduction neurovascular exam, informed consent, reduction technique, number of attempts, use (or nonuse) of anesthesia, and post-reduction imaging if obtained.

23 | Unusual anesthesia | Use if general or regional anesthesia was administered for an otherwise normally non-anesthetized procedure (rare for closed finger reduction). |
