Summary & Overview

CPT 44370: Upper GI Endoscopy with Dilation and Stent Placement

CPT code 44370 denotes a therapeutic upper gastrointestinal endoscopy that includes dilation of a stricture and placement of an endoscopic stent to restore and maintain passage of food. This interventional procedure is a critical option for managing benign and malignant obstructive lesions of the upper digestive tract and has implications for patient symptom relief, nutritional status, and care setting selection. Nationally, CPT code 44370 is relevant across hospital outpatient departments and freestanding endoscopy centers where endoscopic and fluoroscopic resources exist.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when this procedure is used, typical sites of service, and the procedural scope represented by the code. The publication outlines benchmarking and reimbursement context, common claim considerations, and policy or coverage themes that affect utilization of this therapeutic endoscopy nationally.

Billing Code Overview

CPT code 44370 describes an endoscopic procedure in which the provider examines the upper digestive tract (excluding the ileum), dilates a stricture or narrowing, and places a stent through the endoscope to maintain lumen patency for passage of food.

Service type: Therapeutic upper gastrointestinal endoscopy with dilation and stent placement
Typical site of service: Hospital outpatient department or endoscopy center with endoscopic and fluoroscopic capability

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with progressive dysphagia and weight loss presents for endoscopic evaluation. Prior imaging and endoscopy identified an esophageal stricture from malignant or benign etiologies limiting oral intake. The gastroenterologist performs upper endoscopy with dilation of the stricture and transendoscopic placement of an esophageal stent to re-establish luminal patency and allow passage of food. The procedure is performed in an endoscopy suite or operating room under monitored anesthesia care or general anesthesia. The workflow includes pre-procedure consent and history, anesthesia induction, endoscopic inspection of the upper gastrointestinal tract (esophagus, stomach, duodenum), targeted dilation of the narrowed segment, deployment of an esophageal stent through the endoscope, confirmation of stent position and expansion, recovery monitoring, and post-procedure instructions with plan for follow-up imaging or endoscopic reassessment as clinically indicated.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier (standard)	Used when no additional modifier applies; report the service without modifier.
`11`	Principal physician of record	When the reporting clinician is the primary physician directing the case.
`22`	Increased procedural services	When work or complexity substantially exceeds typical expectations for the procedure.
`23`	Unusual anesthesia	When medically necessary and documented unusual anesthesia is required.
`26`	Professional component	When only the physician professional component is reported separate from technical component.
`52`	Reduced services	When the procedure is partially reduced or not completed as originally planned.
`53`	Discontinued procedure	When the procedure is started but discontinued for reasons that do not meet abandonment/complication criteria.
`62`	Two surgeons	When two surgeons work together as primary surgeons; documented and warranted.
`78`	Return to OR for related procedure during postoperative period	For unplanned return to the operating room for a related procedure during the global period.
`80`	Assistant surgeon	When a surgical assistant performs part of the procedure; documentation required.
`82`	Unpaid assistant surgeon	When an assistant surgeon participates but does not receive compensation from the payor.
`73`	Discontinued outpatient prior to anesthesia	If outpatient procedure cancelled after patient taken to procedure area but before anesthesia or sedation.
`50`	Bilateral procedure	Rarely applicable; use only if bilateral anatomic procedures are legitimately reported.
`51`	Multiple procedures	When multiple CPT procedures are performed during same session; list with appropriate sequencing.

Taxonomy Code	Specialty	Notes
`207RP1000X`	Gastroenterology	Gastroenterologists commonly perform diagnostic and therapeutic upper endoscopy with dilation and stent placement.
`207RR0500X`	Surgical Critical Care / Acute Care Surgery	Acute care or thoracic surgeons may place stents in complex malignant upper-GI obstructions.
`2080P0227X`	General Surgery	General surgeons with endoscopic skills perform esophageal stent placement in operative settings.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`C15.9`	Malignant neoplasm of esophagus, unspecified	Esophageal cancer causing obstructive stricture requiring dilation and stent placement.
`K22.2`	Esophageal obstruction	Direct indication for endoscopic dilation and stent placement to relieve obstruction.
`K22.7`	Diverticulum of esophagus	Structural abnormalities that may cause symptomatic narrowing and require endoscopic management.
`K22.8`	Other specified diseases of esophagus	Includes strictures from radiation, caustic injury, or other causes leading to stent placement.
`K21.9`	Gastro-esophageal reflux disease without esophagitis	Chronic reflux can lead to peptic strictures; may require dilation and stenting in refractory cases.

CPT Code	Description	Relationship to This Procedure
`43235`	Esophagogastroduodenoscopy, flexible, transoral; with biopsy, single or multiple	Often performed prior to stent placement for diagnostic evaluation and tissue sampling.
`43239`	Esophagogastroduodenoscopy, flexible, transoral; with dilation of esophagus over guidewire with balloon or bougie	Dilation may be performed alone or prior to stent placement; similar therapeutic intent.
`43269`	Endoscopic placement of esophageal stent (includes pre- and post-dilation when performed)	Alternative or closely related code specific to esophageal stent procedures; may overlap—select the code that best describes the service.
