CPT 22901 Excision — Reimbursement & Policy | OpenPayer

Summary & Overview

CPT 22901: Excision of Intramuscular Abdominal Wall Mass, ≥5 cm

CPT code 22901 captures surgical excision of an intramuscular abdominal wall mass with specimen size 5 cm or greater, submitted for laboratory analysis. This procedure code matters nationally because it designates care for potentially significant soft-tissue masses that require operative management and pathologic diagnosis, affecting surgical, pathology, and facility billing. Common national payers include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise explanation of the code’s clinical scope and service setting, plus national benchmarking context where available. The publication outlines typical sites of service, common payer coverage patterns, and operational considerations relevant to coding and claims submission for sizable intramuscular abdominal wall masses. It also summarizes what metrics to expect when reviewing reimbursement benchmarks and policy updates tied to surgical excision procedures that generate laboratory specimens for pathology.

Billing Code Overview

CPT code 22901 describes the surgical excision of an abnormal mass located within the muscle layer beneath the abdominal wall, with the submitted specimen measuring 5 cm or greater for laboratory analysis to determine its nature. The procedure involves removal of an intramuscular abdominal wall lesion and preparation of the specimen for pathological evaluation.

Service type: Surgical excision of intramuscular abdominal wall mass
Typical site of service: Hospital operating room or ambulatory surgical center

Clinical & Coding Specifications

Clinical Context

A 48-year-old patient presents with a firm, enlarging abdominal wall mass deep to the rectus sheath detected on physical exam and confirmed by abdominal ultrasound and MRI. The lesion measures 6 cm in greatest dimension and is suspected to be an intramuscular lipoma versus desmoid tumor. The surgical team schedules an open excision under general anesthesia. Intraoperatively the surgeon performs a localized incision over the mass, dissects through subcutaneous tissue, opens the anterior rectus fascia, and excises the 6 cm intramuscular lesion with margin control. The specimen is submitted to pathology for gross and microscopic evaluation. Typical perioperative workflow includes preoperative evaluation and consent, anesthesia induction, operative excision with hemostasis, specimen labeling and submission to the laboratory, and postanesthesia recovery. Typical site of service is an outpatient ambulatory surgery center or hospital operating room for procedures under general anesthesia. Service type: surgical excision of an intramuscular abdominal wall mass, specimen ≥5 cm, sent for pathologic analysis, corresponding to 22901.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`D17.9`	Benign lipomatous neoplasm, unspecified site	Intramuscular lipoma is a common benign cause of an abdominal wall mass requiring excision.
`D48.1`	Neoplasm of uncertain behavior of connective and soft tissue	Used when lesion behavior is uncertain before pathology results.
`C49.A9`	Malignant neoplasm of other connective and soft tissue of abdomen, unspecified	Used when preoperative imaging/biopsy suggests a malignant soft tissue tumor requiring wide excision.
`M79.2`	Neuralgia and neuritis, unspecified (used for symptomatic nerve-related pain)	Applicable when lesion causes localized pain or nerve compression prompting excision.
`M60.8`	Other myositis	Occasionally used when inflammatory intramuscular masses or focal myositis mimic tumors and require excision for diagnosis.
