Summary & Overview
CPT 43243: Endoscopic Sclerotherapy for Esophageal or Gastric Varices
CPT code 43243 denotes therapeutic upper gastrointestinal endoscopy with injection of a sclerosing solution into esophageal or gastric varices. This procedure is a targeted endoscopic intervention used to control active bleeding or reduce rebleeding risk from portal hypertension–related varices and is an important component of the acute and elective management of gastrointestinal hemorrhage. Nationally, the code is relevant to hospitals, outpatient endoscopy centers, and payers managing costs and quality of acute GI bleeding care. Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for use of the code, typical sites of service, common billing modifiers and related administrative considerations, and a summary of payer coverage patterns where available. The publication summarizes benchmarks on utilization and reimbursement trends when present, highlights policy and documentation drivers that affect claim adjudication, and outlines coding relationships to other upper endoscopy and variceal treatment services. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 43243 describes an endoscopic procedure in which a flexible endoscope is inserted through the mouth and advanced into the esophagus, stomach, and duodenum to inject a sclerosing solution for treatment of enlarged blood vessels (varices) in the esophagus or stomach. This procedure is a form of therapeutic upper gastrointestinal endoscopy intended to control or prevent bleeding from varices by inducing sclerosis of the abnormal vessels.

Service type: Therapeutic upper gastrointestinal endoscopy with sclerotherapy
-
Typical site of service: Hospital outpatient department or endoscopy suite (ambulatory surgical center when clinically appropriate)
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with a history of alcohol-related cirrhosis and portal hypertension presents with hematemesis and melena. After initial hemodynamic stabilization in the emergency department, the gastroenterology team evaluates the patient and schedules an urgent upper endoscopy. The provider performs an esophagogastroduodenoscopy (EGD) with injection sclerotherapy: a flexible endoscope is passed through the mouth into the esophagus and stomach, and a sclerosing solution is injected into identified variceal columns to achieve hemostasis and reduce rebleeding risk. The clinical workflow includes pre-procedure consent and airway assessment, NPO status confirmation, intravenous access and sedation (moderate sedation or monitored anesthesia care), intraprocedural documentation of variceal location and number of injections, post-procedure recovery with monitoring for rebleeding or chest pain, and discharge instructions or inpatient admission depending on stability and underlying disease severity.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Major procedural service | When this EGD with injection sclerotherapy is the primary service provided during the encounter. |
22 | Increased procedural services | When work effort is substantially greater than typical (e.g., difficult anatomy, extensive injections). |
23 | Unusual anesthesia | When general anesthesia is required for medically necessary reasons beyond routine sedation. |
52 | Reduced services | When the procedure is started but not completed as originally planned (partial sclerotherapy). |
53 | Discontinued procedure | When the procedure is terminated due to a patient adverse event or safety concern before completion. |
62 | Two surgeons | When two physicians of the same specialty participate, usually for teaching or complex cases. |
66 | Surgical team | When a defined surgical team approach is used for complex endoscopic therapy. |
78 | Unplanned return to OR/procedure | When the patient returns to the endoscopy suite for related treatment during the global period. |
80 | Assistant surgeon | When a qualified assistant surgeon provides active help during the procedure. |
81 | Minimum assistant surgeon | When a minimal level of assistant participation is documented. |
82 | Assistant not available | When a qualified assistant is not available and documented. |
73 | Discontinued outpatient procedure prior to anesthesia | When the outpatient procedure is cancelled after patient is prepared but before sedation/anesthesia. |
52 | Reduced services | When fewer injections or limited therapy is documented compared with full service. |
TC | Technical component | When billing only the facility/technical component separate from the physician professional service. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
3336C0001X | Gastroenterology | Endoscopic diagnosis and treatment of varices is commonly performed by gastroenterologists trained in advanced endoscopy. |
207K00000X | General Surgery | Surgeons with endoscopic skills may perform therapeutic upper endoscopy in surgical settings. |
2080S0003X | Critical Care Medicine | Critical care physicians may perform or assist with urgent endoscopic hemostasis in unstable patients. |
334J00000X | Pediatric Gastroenterology | Pediatric specialists perform similar procedures in pediatric populations when indicated. |
363L00000X | Anesthesiology | Anesthesiologists provide sedation or general anesthesia for complex or high-risk cases. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I85.01 | Esophageal varices with bleeding | Primary indication for endoscopic sclerotherapy to control active variceal hemorrhage. |
I85.00 | Esophageal varices without bleeding | Presence of varices may prompt prophylactic or elective therapy in certain clinical contexts. |
K74.60 | Unspecified cirrhosis of liver | Underlying cirrhosis often causes portal hypertension leading to variceal formation. |
I86.4 | Gastric varices | Gastric varices can be treated via endoscopic injection sclerotherapy when identified as bleeding sources. |
K72.90 | Hepatic failure, unspecified, without coma | Severe liver dysfunction increases bleeding risk and influences peri-procedural management. |
R04.0 | Epistaxis (not related) | Data not applicable — excluded. |
