Summary & Overview

CPT 23078: Extensive Excision of Shoulder Soft Tissue Malignant Tumor

CPT code 23078 denotes an extensive surgical excision of a malignant soft tissue tumor in the shoulder region, applied when the tumor and required margins measure 5 cm or greater. This code captures wide local excisions that remove adjacent anatomic structures suspected of involvement, reflecting higher-complexity oncologic surgery. Nationally, the code matters for appropriate classification of operative complexity, resource use, and payer coverage decisions for sarcoma and other soft tissue malignancies involving the shoulder.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of what 23078 represents clinically and operationally, how typical sites of service and service type align with coding practice, and which major payers are relevant to coverage and reimbursement conversations. The publication also outlines common modifiers and related administrative details found in the input, and flags where input data is not available.

Readers will gain a practical reference for clinical coding teams, billing staff, and policy analysts seeking to classify extensive shoulder soft tissue tumor excisions accurately and to understand payer relevance and typical service settings at a national level.

Billing Code Overview

CPT code 23078 describes an extensive excision of a soft tissue malignant tumor (for example, a sarcoma) from the shoulder region. The procedure involves removal of the tumor with wide margins extending beyond the visible tumor and includes surrounding anatomical structures suspected of involvement. The described resection applies when the tumor diameter and required margins measure 5 cm or more.

Service type: Extensive surgical excision for malignant soft tissue tumor

Typical site of service: Hospital operating room or ambulatory surgical center (shoulder/upper extremity surgical setting)

Clinical & Coding Specifications

Clinical Context

A 62-year-old patient presents with a progressively enlarging, firm mass over the left shoulder with intermittent pain and limited range of motion. Imaging with MRI demonstrates a deep soft tissue lesion measuring 6.5 cm with suspicious margins and involvement of adjacent deltoid fascia. Core needle biopsy yields a high-grade soft tissue sarcoma. The multidisciplinary tumor board recommends wide local excision with en bloc removal of involved soft tissue and margin sampling. The patient is scheduled for an operative procedure under general anesthesia in an ambulatory surgical center or hospital operating room. The procedure includes preoperative marking, intraoperative orientation of margins, resection of the tumor with at least 5 cm combined tumor-plus-margin diameter, hemostasis, possible drain placement, and specimen labeling for pathology. Postoperative care includes pain control, wound care instructions, and coordination with medical and radiation oncology for adjuvant therapy decisions based on final pathology.
