Summary & Overview
CPT 23665: Closed Treatment of Shoulder Dislocation with Greater Tuberosity Reduction
CPT code 23665 represents a closed treatment procedure for shoulder joint dislocation combined with reduction of a greater humeral tuberosity fracture and manipulation of the shoulder. Nationally relevant for acute orthopedic and emergency care settings, the code captures non‑open management of complex shoulder injuries that often require imaging, sedation or anesthesia, and post‑procedure follow‑up.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about when this procedure is billed, the typical sites of service (hospital outpatient departments, ambulatory surgical centers, and emergency settings), and how the code aligns with acute orthopedic workflows. The publication also summarizes common billing considerations and performance benchmarks where available, and highlights policy and coding guidance updates that affect national reimbursement and claims processing.
This summary aims to help billing professionals, orthopedic and emergency clinicians, and policy analysts understand the clinical intent of CPT code 23665, typical use cases, and the payer landscape affecting coverage and claims handling.
Billing Code Overview
CPT code 23665 describes a procedure for closed treatment of a shoulder joint dislocation with reduction of a greater humeral tuberosity fracture and manipulation to passively move and stretch the shoulder joint. The procedure combines non‑open reduction techniques for a dislocated shoulder, closed reduction of an associated greater tuberosity fracture, and joint manipulation.
-
Service type: Closed treatment, fracture reduction, and manipulation of the shoulder joint
-
Typical site of service: Hospital outpatient department or ambulatory surgical center, and emergency department or urgent care when performed urgently
Clinical & Coding Specifications
Clinical Context
A 58-year-old male presents to the emergency department after a fall onto his outstretched hand with immediate severe left shoulder pain, visible deformity, and inability to move the arm. Emergency department clinicians obtain shoulder radiographs demonstrating an anterior glenohumeral dislocation with an associated displaced greater tuberosity fracture of the proximal humerus. After informed consent, the orthopedic surgeon performs a closed reduction of the glenohumeral dislocation with procedural sedation, performs closed reduction of the greater tuberosity fragment, and manipulates the shoulder to restore alignment and joint mobility. Post-reduction radiographs confirm successful reduction of the humeral head and acceptable position of the greater tuberosity. The patient is placed in a sling with post-procedure analgesia and outpatient orthopedic follow-up arranged.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normal or routine service | Use when the service is the usual, expected procedure without unusual circumstances |
22 | Increased procedural services | Use when additional work beyond the typical service is documented (eg, prolonged manipulation, complex reduction) |
