CPT 23655 Closed Shoulder Reduction Reimbursement | OpenPayer

Summary & Overview

CPT 23655: Closed Reduction of Shoulder Dislocation Under Anesthesia

CPT code 23655 represents the closed reduction of a shoulder joint dislocation performed with anesthesia. This procedure is a common acute orthopedic intervention to restore joint alignment without open surgery, often performed emergently or in an operating room or ambulatory surgery center under monitored anesthesia care or general anesthesia. Nationally, accurate coding of 23655 matters for timely acute care billing, appropriate facility and anesthesia reimbursement, and clear clinical documentation of emergent musculoskeletal management.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines expectations across major commercial payers and the federal payer for coding, typical sites of service, and common claims considerations.

Readers will find concise benchmarks and comparisons of coverage posture, notes on coding and billing context for acute shoulder reductions, and clinical context describing when 23655 is the appropriate code choice versus other procedural or anesthesia codes. Data not provided in the input—such as payer-specific reimbursement rates, ICD-10 pairings, and provider taxonomies—is noted as unavailable where relevant. The content is presented to inform health plans, billing professionals, and clinical staff about coding implications and typical care settings for this acute orthopedic procedure.

Billing Code Overview

CPT code 23655 describes a closed treatment of shoulder dislocation performed under anesthesia. This procedure addresses an abnormal separation of the shoulder joint (glenohumeral dislocation) by manipulating the joint back into place without an open surgical incision.

Service type: Closed reduction of shoulder dislocation under anesthesia
Typical site of service: Hospital operating room or ambulatory surgery center where anesthesia services are available

Clinical & Coding Specifications

Clinical Context

A 28-year-old male presents to the emergency department after a fall during a recreational soccer match with acute left shoulder pain, visible deformity, and inability to actively move the arm. On exam there is anterior prominence of the humeral head and neurovascular status is intact. Radiographs confirm an anterior glenohumeral dislocation without associated large fracture fragments. The orthopedic or emergency physician performs a 23655 closed reduction of the shoulder under procedural anesthesia (conscious sedation or general anesthesia as clinically indicated). Post-reduction radiographs confirm concentric reduction and the arm is immobilized in a sling or shoulder immobilizer. The clinical workflow includes initial assessment, informed consent for closed reduction under anesthesia, administration of anesthesia per institutional protocol, closed reduction maneuver, post-reduction imaging, neurovascular reassessment, documentation of the technique and anesthesia used, and discharge with follow-up instructions and orthopedic clinic referral as needed.
