CPT Code 43245 Complete Billing & Coding Guide for EGD with Dilation of Gastric or Duodenal Strictures

CPT code 43245 is frequently used to bill therapeutic upper gastrointestinal endoscopy that includes treatment of gastric or duodenal narrowing. It is essential to have proper documentation and accurate code selection as claims often demand clear documentation of the location, severity, and therapeutic procedure that was carried out. 

As this is not only a diagnostic procedure but also a therapeutic process. It will involve endoscopic intervention, in which payers are usually requiring detailed documentation to support the Gastroenterology medical necessity. In Gastroenterology medical billing, reporting accurately will help minimize denials and ensure proper reimbursement for therapeutic endoscopy services. 

CPT 43245 Description

Official Definition:
"Esophagogastroduodenoscopy, flexible, transoral; with dilation of gastric/duodenal stricture(s) (e.g., balloon, bougie)."

CPT 43245 describes an upper gastrointestinal endoscopic procedure in which a flexible endoscope is advanced through the mouth to examine the esophagus, stomach, and duodenum. During the procedure, the physician identifies a narrowing within the stomach or duodenum and performs dilation using a balloon, bougie, or similar device to improve luminal patency.

The procedure is commonly performed to relieve symptoms caused by gastric outlet obstruction or other benign and malignant strictures. The diagnostic EGD component is included in the code and should not be reported separately.

The service includes

• Flexible transoral esophagogastroduodenoscopy (EGD)
• Examination of the upper gastrointestinal tract
• Identification of gastric or duodenal strictures
• Dilation using balloon, bougie, or similar devices
• Assessment of post-dilation results

However, CPT 43245 does not include

• Separate billing of the diagnostic EGD
• Esophageal dilation procedures
• Additional reporting for multiple gastric or duodenal strictures treated during the same session
• Unbundling of included endoscopic services

Clinical Indications for CPT 43245

CPT 43245 will be used when the symptoms or functional obstruction of the stomach or duodenum is due to a gastric or duodenal stricture. This is frequently performed to restore food flow and increase gastrointestinal function. 

Typical indications include

• Gastric outlet obstruction
• Benign gastric strictures
• Duodenal strictures
• Narrowing due to peptic ulcer disease 
• Post surgical scarring and stenosis. 
• Chronic pancreatitis-associated obstruction
• Malignant gastric or duodenal narrowing
• Difficulty eating, nausea, or vomiting caused by obstruction

The procedure may also be performed when a stricture is identified during diagnostic endoscopy and immediate treatment is clinically indicated.

Medical Necessity Criteria for CPT 43245

The usual criteria to determine medical necessity are the presence of symptoms associated with a gastric or duodenal stricture, abnormal gastric emptying, or gastric or duodenal obstruction that necessitates endoscopic intervention. Documentation should include a description of the site of narrowing and how severe it is and why dilation is required. 

Some factors that can support include: 

• Symptomatic gastric outlet obstruction
• Persistent nausea or vomiting
• Difficulty tolerating oral intake
• Benign or malignant strictures
• Radiologic or endoscopic evidence of luminal narrowing

Reimbursement Insights for CPT 43245

The reimbursement for CPT 43245 is higher than for a diagnostic EGD alone and is deemed to be a therapeutic procedure. There is usually coverage for those with documentation of a gastric or duodenal (2nd part of the duodenum) stricture that is obstructing the passage of food.

Key reimbursement considerations

• Medicare and most commercial health insurance companies will cover this when medically necessary 
• Reimbursement for therapeutic EGD is typically more than reimbursement for diagnostic EGD. 
• Global period: 000 days
• Diagnostic EGD is bundled into CPT 43245
• Multiple gastric or duodenal strictures treated during the same session are reported as one unit
• Reimbursement varies based on payer, geographic region, and site of service
• Hospital Outpatient Departments (HODs) and ASCs may get reimbursed at different facility rates. 

Applicable Modifiers for CPT 43245

Modifier selection depends on procedural circumstances and any additional services performed during the encounter. Proper documentation should support all modifier usage.

Common modifiers

• Modifier -22: Hospital Outpatient Departments (HODs) and ASCs may get reimbursed at different facility rates. 
• Modifier -52: Used when the planned dilation service is partially reduced or not fully completed.
• Modifier -53: Used when the procedure is discontinued due to patient safety concerns, technical limitations, or clinical instability.
• Modifier -59 or X{EPSU}: Used when a separate and distinct procedure is performed and meets payer requirements for separate reporting.
• Modifier -74: May be reported in facility settings when the procedure is discontinued after anesthesia administration.

Important billing rule:

CPT 43245 should be reported as the comprehensive therapeutic service when gastric or duodenal dilation is performed. The diagnostic EGD should not be billed separately.

Documentation Requirements for CPT 43245

Thorough documentation is necessary to justify medical necessity and selection of the appropriate codes. The location of the stricture should be clearly identified in the procedure report and the dilation that was performed should be described.

Documentation should include

• Medical indication for dilation
• Symptoms associated with the stricture
• Gastric or duodenal location of the stricture 
• Severity and characteristics of the narrowing
• Dilation method used (balloon, bougie, etc.)
• Size of the dilation device utilized
• Number of dilation attempts performed
• Post-dilation findings
• Any complications or procedural limitations
• Patient tolerance of the procedure
• Signed final procedure report

Example Clinical Scenarios

Scenario 1: Gastric Outlet Obstruction Due to Peptic Ulcer Disease

A 67-year-old patient complains of ongoing nausea, vomiting and inability to tolerate solid food. The gastroenterologist finds a benign pyloric stricture during upper endoscopy, which is associated with chronic peptic ulcer disease. Balloon dilation is used to open up the blockage. 

→ Coding Outcome: CPT 43245

→ Rationale: Therapeutic dilation of a gastric stricture was performed during EGD.

Scenario 2: Duodenal Stricture Associated with Chronic Pancreatitis

A patient with a history of chronic pancreatitis undergoes upper endoscopy for worsening symptoms of gastric outlet obstruction. A duodenal stricture is identified and successfully dilated using an endoscopic balloon.

→ Coding Outcome: CPT 43245

→ The rationale for reporting CPT 43245 for EGD with dilation of a duodenal stricture is that it is considered a distinct procedure.  

Scenario 3: Malignant Gastric Stricture Treatment

In gastric cancer, the narrowing comes progressively and reduces the oral intake. A gastric stricture can be identified and dilated during an endoscopy, which will help to improve gastric emptying and control symptoms. 

→ Coding Outcome: CPT 43245

→ Rationale: Therapeutic dilatation of malignant gastric stricture performed. 

Scenario 4: Procedure Discontinued Due to Technical Difficulty

Endoscopic dilation is performed on a patient with a severe duodenal stricture. The physician is unable to move the dilation device safely forward and/or is concerned about the safety of the procedure, so it is discontinued before completion. 

→ Coding Outcome: CPT 43245-53

→ Rationale: The procedure did not complete due to technical limitations and patient safety concerns.
