Summary & Overview
CPT 23073: Excision of Intramuscular Shoulder Mass, Specimen ≥5 cm
CPT code 23073 represents the surgical excision of an intramuscular mass or tumor of the shoulder when the submitted specimen is 5 cm or greater. This code captures a specific surgical oncology procedure with implications for operative planning, pathology processing, and facility resource use. Nationally, accurate coding for larger musculoskeletal tumor excisions impacts procedure classification, facility billing, and aggregated surgical quality metrics.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, typical site-of-service considerations, and the types of benchmarks and policy topics commonly associated with such procedures, including reimbursement benchmarks, coding compliance considerations, and documentation requirements tied to specimen size.
The publication provides: (1) procedural and clinical context for CPT code 23073; (2) common payer coverage patterns and where variation commonly arises; and (3) operational and billing elements that affect hospital and ambulatory surgery center reporting. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 23073 describes the surgical excision of an abnormal mass or tumor located within the muscle tissue of the shoulder, with the submitted specimen measuring 5 cm or greater. The procedure involves removal of an intramuscular shoulder lesion and submission of the specimen for pathologic analysis and diagnosis.
Service type: Surgical excision
Typical site of service: Hospital operating room or ambulatory surgery center, where formal surgical excision and specimen submission for laboratory analysis are performed.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with a palpable, enlarging mass deep within the deltoid/shoulder musculature noted to be at least 5 cm on imaging (ultrasound or MRI). The mass is painful with restricted shoulder motion and has suspicious imaging features for a soft-tissue neoplasm. After preoperative evaluation in the orthopedic oncology or general orthopedics clinic, the patient is scheduled for operative excision of the intramuscular shoulder mass under general anesthesia in an ambulatory surgery center or hospital outpatient department. Intraoperative steps include localization of the lesion, careful dissection through muscle layers to excise the mass with appropriate margins, hemostasis, and submission of the specimen (≥5 cm) to pathology for gross and microscopic analysis. Postoperative care includes wound management, pain control, and coordination of pathology results to determine need for additional oncologic treatment or surveillance.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
50 | Bilateral procedure | Use when the same procedure is performed on both shoulders during the same operative session. |
51 | Multiple procedures | Use when additional distinct procedures are performed at the same session in addition to the excision. |
