Summary & Overview
CPT 43501: Open Gastric Hemostasis, Incision and Vessel Ligation
CPT code 43501 represents an open surgical gastric hemostasis procedure—an incision through the abdomen into the stomach with ligation of a bleeding vessel to control active intragastric hemorrhage. This code is clinically significant because it documents a definitive operative intervention for potentially life‑threatening gastrointestinal bleeding and is associated with inpatient surgical care, resource-intensive operative and postoperative management, and acute reimbursement considerations.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the codes clinical context and where the procedure is commonly performed, along with benchmarking and policy-relevant guidance on how this service is typically classified across major payers. The publication outlines expected sites of service, common modifiers used with this surgical code, and the elements that commonly affect claims processing and reimbursement. It also highlights coding relationships and clinical scenarios that prompt use of this code.
The goal is to equip coding, billing, and clinical teams with a clear national-level summary of CPT code 43501, its clinical purpose, and operational implications for claims and utilization tracking. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 43501 describes a surgical procedure in which the provider makes an incision in the stomach through the abdomen and ties off a bleeding vessel. This procedure is a form of open gastric hemostasis intended to control active hemorrhage within the stomach.
-
Service type: Open surgical gastric hemostasis
-
Typical site of service: Inpatient or operating room setting where abdominal surgery is performed
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with acute upper abdominal pain, gastrointestinal bleeding, or hemodynamic instability after trauma or a bleeding gastric ulcer. The patient often arrives through the emergency department with signs of ongoing hemorrhage such as hematemesis, melena, tachycardia, hypotension, or a falling hemoglobin. After initial resuscitation (IV access, fluid/blood product administration, oxygen), diagnostic workup includes laboratory studies, nasogastric lavage as indicated, and upper endoscopy when feasible. If endoscopic hemostasis fails, bleeding is not localized endoscopically, or the patient remains unstable, the surgical team proceeds to the operating room. The provider performs an exploratory laparotomy or laparoscopic approach, makes an incision in the stomach (gastrotomy), identifies the bleeding vessel within the gastric wall or ulcer base, and achieves definitive hemostasis by ligation (ties off the bleeding vessel). Postoperative care includes monitoring in a recovery area or intensive care unit, serial hemoglobin checks, proton pump inhibitor therapy, and coordination with gastroenterology for ulcer management and with interventional radiology if adjunctive embolization is considered.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure required substantially greater work or time than typical. |
23 | Unusual anesthesia | Use when general anesthesia was required but the procedure was normally done with local/regional anesthesia. |
26 | Professional component | Use when reporting only the professional component of a service (rare for operative codes). |
50 | Bilateral procedure | Use when the procedure was performed bilaterally (not typically applicable to gastrotomy but included for completeness). |
51 | Multiple procedures | Use when multiple distinct procedures are performed in the same operative session. |
52 | Reduced services | Use when the service was partially reduced or not completed as described. |
53 | Discontinued procedure | Use when the procedure was started but terminated due to extenuating circumstances. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions. |
66 | Surgical team | Use when services are provided by a surgical team (e.g., in complex cases). |
78 | Return to OR for related procedure during postoperative period | Use when the patient returns to the operating room for a related procedure during the global period. |
80 | Assistant surgeon | Use when a surgical assistant participates. |
81 | Minimum assistant surgeon | Use when a minimum assistant surgeon is documented. |
82 | Assistant surgeon (when qualified resident not available) | Use when assistant surgeon is provided because no qualified resident is available. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 208000000X | General Surgery | Most common specialty performing gastrotomy with hemostasis. |
| 208600000X | Surgical Critical Care | Manages critically ill patients perioperatively and may perform operative procedures in emergent settings. |
| 207L00000X | Emergency Medicine | Often involved in initial resuscitation and coordination; may facilitate operative transfer. |
| 207K00000X | Gastroenterology | Performs diagnostic endoscopy and may attempt endoscopic hemostasis prior to surgical intervention. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
K25.0 | Acute gastric ulcer with hemorrhage | Represents a common cause of bleeding requiring operative ligation when endoscopic therapy fails. |
K25.2 | Chronic or unspecified gastric ulcer with hemorrhage | Chronic ulcers can erode vessels leading to hemorrhage needing surgical control. |
K92.2 | Gastrointestinal hemorrhage, unspecified | General code for GI bleeding when site or cause is initially unclear; may lead to exploratory gastrotomy. |
S36.0 | Injury of stomach | Traumatic injury to the stomach causing active bleeding that may require gastrotomy and vessel ligation. |
I85.00 | Esophageal varices with bleeding, without ascites | Variceal bleeding can present similarly; while ligation is endoscopic, operative control may be required for associated gastric bleeding. |
