Summary & Overview
CPT 0654T: Transnasal Upper GI Endoscopy with Intraluminal Catheter
CPT code 0654T denotes a diagnostic transnasal upper gastrointestinal endoscopy with insertion of a tube or catheter into the lumen of the GI tract. Nationally, this code captures a minimally invasive diagnostic approach for evaluating the esophagus, stomach, and duodenum when transoral access is not used or when catheter placement is required. It matters because appropriate coding affects clinical documentation, facility and professional billing, and payer adjudication for advanced endoscopic approaches.
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 clinical procedure linked to CPT code 0654T, standard sites of service where the procedure is performed, and the payer landscape relevant to national coverage and billing practices. The publication provides benchmarks where available, summarizes policy and coding considerations that affect claims processing, and situates the procedure within clinical care pathways for upper GI diagnostic evaluation.
This summary is intended for providers, coding professionals, and payer analysts seeking a clear, national-level reference for CPT code 0654T and its use in diagnostic upper gastrointestinal endoscopy with intraluminal catheter placement.
Billing Code Overview
CPT code 0654T describes a diagnostic upper gastrointestinal endoscopy in which the provider inserts an endoscope through the nose and advances it into the esophagus, stomach, and duodenum. The procedure also involves insertion of a tube or catheter into the lumen of the gastrointestinal tract for diagnostic purposes.
-
Service type: Diagnostic endoscopic upper GI procedure with transnasal endoscope and intraluminal catheter/tube placement
-
Typical site of service: Ambulatory surgical center or hospital outpatient department; may also occur in endoscopy suites or specialized procedural clinics

Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old adult referred to gastroenterology for upper gastrointestinal symptoms such as persistent dyspepsia, chronic heartburn refractory to medical therapy, upper abdominal pain, melena, or unexplained iron-deficiency anemia. After history, physical exam, and noninvasive testing (labs, H. pylori testing, or abdominal imaging as indicated), the provider schedules a diagnostic transnasal esophagogastroduodenoscopy with catheter insertion for luminal assessment and potential sampling. The procedure is performed in an ambulatory surgery center or endoscopy suite; typical site of service is the endoscopy unit or hospital outpatient department. The patient receives topical nasal anesthesia and moderate sedation or monitored anesthesia care depending on comorbidity and institutional protocols. The provider advances a thin endoscope through the nasal passage into the esophagus, stomach, and duodenum to inspect mucosa, obtain biopsies, and, when indicated, insert a catheter or tube into the gastrointestinal lumen for diagnostic contrast injection, pH/impedance catheter placement, or targeted sampling. Recovery and post-procedure observation occur in the same endoscopy unit until discharge criteria are met. Common clinical indications include evaluation of upper GI bleeding, suspected peptic ulcer disease, surveillance of Barrett esophagus, progressive dysphagia, or evaluation of persistent nausea/vomiting.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier applicable | Rarely used; placeholder in some systems when no modifier is reported |
22 | Increased procedural services | When work required is substantially greater than usual (extensive adhesiolysis, difficult anatomy) |
23 | Unusual anesthesia | When general anesthesia is medically necessary and not routinely used for the procedure |
52 | Reduced services | When the procedure is partially performed or curtailed |
53 | Discontinued procedure | When the procedure is started but abandoned due to unforeseen circumstances |
59 | Distinct procedural service | When a separate non-overlapping service is performed the same day (distinct catheter placement vs other endoscopic procedures) |
62 | Two surgeons | When two surgeons work together as primary surgeons |
66 | Surgical team | When a surgical team is required for complex combined procedures |
73 | Discontinued outpatient hospital/ambulatory procedure prior to anesthesia | Procedure stopped before anesthesia administration |
78 | Unplanned return to the operating/procedure room | For repeat endoscopy during same hospitalization for a related problem |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
