CPT 43611: Excision of Cancerous Stomach Tumor

Headline: CPT code 43611 covers surgical excision of a cancerous stomach tumor, a key procedure in gastric cancer care.

Lead: CPT code 43611 denotes the surgical removal of a malignant gastric tumor to prevent metastasis or to debulk the tumor ahead of radiation or chemotherapy. This operative intervention is central to multidisciplinary cancer management and impacts surgical services utilization and payer reimbursement patterns nationally.

Why it matters: Surgical excision for gastric malignancy directly affects patient prognosis, care pathways, and resource allocation across inpatient and outpatient surgical settings. As definitive or cytoreductive therapy, the procedure influences subsequent oncologic treatments and hospital surgical volumes.

Key payers covered: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare are the primary payers referenced for national coverage and reimbursement considerations.

What readers will learn: The publication provides clinical context for CPT code 43611, outlines typical sites of service, and summarizes the code’s relevance to surgical oncology workflows. Readers will find benchmarks and policy-relevant observations where data is available, along with practical coding context for billing teams and clinical administrators. Data not available in the input will be identified as such.

Clinical & Coding Specifications

Clinical Context

A 64-year-old patient with biopsy-proven gastric adenocarcinoma presents with a bulky, localized gastric tumor causing symptoms of early satiety and weight loss. Imaging (CT abdomen/pelvis with contrast) demonstrates a primary gastric mass without distant metastasis but with concern for regional lymph node involvement. The multidisciplinary tumor board recommends excisional resection of the gastric tumor to reduce tumor burden prior to neoadjuvant chemotherapy and radiation or to attempt curative resection depending on intraoperative findings. The patient is evaluated preoperatively by surgical oncology, medical oncology, and anesthesia; informed consent is obtained. On the day of service the patient undergoes general endotracheal anesthesia, operative excision of the gastric tumor (partial gastrectomy or tumor excision depending on location and extent), intraoperative frozen section as indicated, hemostasis, and placement of drains as needed. Postoperative inpatient recovery includes pain control, early ambulation, diet advancement per enhanced recovery after surgery (ERAS) protocol, pathology review of the specimen for margin status, and coordination of adjuvant or neoadjuvant therapy with oncology based on final staging.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when the procedure requires substantially greater work than normal due to severity, such as extensive tumor resection with complex reconstruction.
`23`	Unusual anesthesia	Use when general anesthesia is contraindicated and substantially more risky or unusual anesthesia techniques are required.
`26`	Professional component	Use if reporting a professional-only service component separately (rare for operative CPT).
`50`	Bilateral procedure	Use if identical gastric procedures are performed bilaterally on paired organs (not typically applicable to stomach; include only if bilateral procedure logic applies).
`51`	Multiple procedures	Use when additional distinct surgical procedures are performed at the same session in addition to the primary excision.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the procedure is terminated due to extenuating circumstances after anesthesia induction.
`59`	Distinct procedural service	Use to indicate a separate, distinct procedure performed on the same day that is not usually reported together.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the tumor excision.
`63`	Procedure performed on infants less than 4 kg	Use only when patient meets pediatric weight criteria (unlikely for adult gastric cancer).
`78`	Return to operating room for related procedure during postoperative period	Use if a related re-operation is performed for complications of the initial excision.
`79`	Unrelated procedure or service by the same physician during postoperative period	Use when an unrelated procedure occurs during the global period (note: `79` is not in the provided modifier list; therefore do not use).
`80`	Assistant surgeon	Use when an assistant surgeon is documented and required for the tumor excision.
`81`	Minimum assistant surgeon	Use when a minimal assistant is documented.

Taxonomy Code	Specialty	Notes
207X00000X	General Surgery	Surgeons who perform gastric tumor excisions and partial gastrectomy procedures.
2080P0207X	Surgical Oncology	Specialists in oncologic resections including gastric cancer surgery.
207L00000X	Thoracic Surgery	Involved when tumor location or combined thoracoabdominal approach is necessary.

`C16.2`	Malignant neoplasm of body of stomach	Common primary site for gastric adenocarcinoma treated with excision.
`C16.3`	Malignant neoplasm of antrum, pyloric	Distal gastric tumors often require resection and reconstruction.

`C16.5`	Malignant neoplasm of greater curvature of stomach	Tumors here may need surgical excision to reduce bulk and enable adjuvant therapy.
`C16.9`	Malignant neoplasm of stomach, unspecified	Used when the gastric tumor location is not specified but excision is performed.
