Summary & Overview
CPT 23520: Closed Treatment of Sternoclavicular Joint Dislocation
CPT code 23520 represents the closed, nonoperative treatment of a sternoclavicular joint dislocation performed without manipulation or open surgery. This code captures a distinct, typically acute orthopedic service addressing separation of the sternoclavicular joint using conservative measures. Nationally, accurate coding for such emergency and urgent musculoskeletal interventions is important for clinical documentation, appropriate claims adjudication, and epidemiologic tracking of traumatic joint injuries.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical sites of service, and how the procedure is characterized in claims. The publication outlines what stakeholders can expect when comparing coverage positions and payment policies across major commercial payers and Medicare, highlights benchmark considerations for nonoperative joint care, and summarizes relevant coding context for billing teams and health system administrators.
The report provides national-level insights into utilization patterns, billing considerations, and policy updates relevant to nonoperative management of sternoclavicular dislocations. Data not available in the input is noted where applicable, and the content focuses on clinical definition, coding clarity, and payer coverage landscape rather than clinical recommendations.
Billing Code Overview
CPT code 23520 describes a closed treatment of a sternoclavicular joint dislocation performed without manipulation or open surgery. The procedure addresses an abnormal separation of the sternoclavicular joint by nonoperative means when no adjustment or surgical intervention is required.

- Service type: Closed management of a joint dislocation (nonoperative)
Typical Site of Service
- Typical site of service: Emergency department, urgent care, or outpatient orthopedic clinic where nonoperative joint management is performed
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after a bicycle collision with acute pain and visible prominence at the base of the neck on the right side. Physical exam suggests a sternoclavicular joint dislocation without skin compromise or neurovascular deficit. Plain radiographs and, if needed, a CT scan confirm an isolated sternoclavicular joint dislocation. The treating emergency physician or orthopedic surgeon performs a closed treatment consisting of immobilization and potential external stabilization (sling, figure-of-eight bandage, or towel roll placement) without manual reduction or operative intervention. The clinical workflow includes initial triage, focused history and exam, imaging to confirm diagnosis and rule out mediastinal injury, informed consent for closed nonoperative management, application of immobilization, post-procedure neurovascular reassessment, discharge instructions with analgesia, and outpatient orthopedic follow-up within 7–14 days for re-evaluation and possible advanced management if instability persists.
