Summary & Overview
CPT 25073: Excision of Deep Soft Tissue or Intramuscular Mass, Forearm/Wrist
CPT code 25073 denotes the surgical excision of an abnormal mass situated in the deep soft tissue or within muscle of the forearm or wrist, with submission of a specimen 3 cm or larger for laboratory analysis. This code captures a targeted operative procedure used to remove potentially neoplastic or symptomatic masses from deeper anatomic planes of the distal upper extremity and is important for accurate clinical documentation, coding, and reimbursement for surgical specialties including orthopedics and plastic surgery.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national perspective on clinical context, coding characterization, and common billing considerations tied to the service type and typical sites of service. The publication outlines benchmarks for utilization and payment where available, summarizes relevant policy and coverage themes affecting this category of procedures, and clarifies the clinical scenarios that typically prompt use of the code. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 25073 describes the excision of an abnormal mass located in the deep soft tissues or within the muscle of the forearm or wrist. The procedure includes removal of a specimen that is 3 cm or greater in size and submission of that specimen to a laboratory for analysis to determine its nature.
Service type: Surgical excision of deep soft tissue or intramuscular mass
Typical site of service: Operative setting such as an ambulatory surgery center or hospital operating room, with preoperative and postoperative care consistent with surgical procedures of the forearm or wrist.
Clinical & Coding Specifications
Clinical Context
A 46-year-old right-hand-dominant patient presents to an outpatient surgical clinic with a palpable, progressively enlarging deep soft tissue mass in the volar forearm near the wrist. The mass is firm, non-tender, approximately 3.5 cm on clinical exam and MRI shows a well-circumscribed intramuscular lesion within the flexor compartment without radiographic invasion of bone. The patient is scheduled for operative excision under regional block or monitored anesthesia care in an ambulatory surgery center. The surgeon performs dissection to the deep soft tissues/muscle, excises the lesion en bloc, and submits a specimen greater than 3 cm to the pathology laboratory for histologic evaluation to determine benign versus malignant etiology. Intraoperative steps include localization of neurovascular structures, hemostasis, specimen orientation and labeling, and closure. Postoperative workflow includes recovery, pathology result review, and follow-up for wound check and discussion of final diagnosis and further oncologic referral if malignancy is identified.
