CPT 23660 Open Shoulder Reduction Reimbursement | OpenPayer

Summary & Overview

CPT 23660: Open Treatment of Acute Shoulder Dislocation

CPT code 23660 represents an open surgical procedure for the treatment of an acute shoulder dislocation, typically performed when closed reduction is not feasible or when the injury is a posterior dislocation requiring direct visualization. This procedure is clinically significant because it addresses unstable or complex dislocations that can lead to persistent pain, dysfunction, or neurovascular compromise if not properly reduced.

Key payers in the national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for surgical management of shoulder dislocations, common billing considerations, and payer coverage patterns. The publication also covers procedural benchmarks and coding nuances relevant to surgical service lines and hospital billing.

The report provides guidance on where the service is typically performed (operating room in inpatient or outpatient surgical settings) and how the code fits into surgical care pathways for shoulder trauma. Data not available in the input is noted where applicable. The content is intended for coding professionals, revenue cycle staff, and clinical leaders seeking a concise reference on CPT code 23660 and its role in surgical management of acute shoulder dislocation.

Billing Code Overview

CPT code 23660 describes an open treatment of an acute shoulder dislocation. The procedure involves making an incision to expose the shoulder joint and performing a reduction to return the humeral head to its proper position. This service is most often used for posterior shoulder dislocations, where the humeral head is displaced toward the back of the body.

Service type: Open surgical reduction of shoulder dislocation

Typical site of service: Operative suite / hospital inpatient or outpatient surgical setting

Clinical & Coding Specifications

Clinical Context

A 28-year-old male motorcyclist is brought to the emergency department after a collision. He complains of severe left shoulder pain and inability to move the arm. Physical exam shows a posterior prominence of the humeral head and limited external rotation. Radiographs confirm a posterior shoulder dislocation with associated soft-tissue interposition that prevents closed reduction. The orthopaedic surgeon discusses open reduction under general anesthesia and performs 23660 — open treatment of acute shoulder dislocation with reduction. The typical clinical workflow includes preoperative evaluation and imaging (plain radiographs, CT if fracture or chronicity suspected), informed consent, operating room preparation, general anesthesia, surgical approach to the glenohumeral joint, reduction of the humeral head, inspection and management of concomitant labral or bony injury, wound closure, postoperative radiographs to confirm reduction, recovery in PACU, and discharge with sling, pain control, and follow-up for rehabilitation.
