FGEC™ – Fellowship in Gastroenterology Coding The FGEC™ – Fellowship in Gastroenterology Coding is an advanced specialty training program designed to build expertise in Gastroenterology Medical Coding, complex endoscopic procedures, and documentation-driven reimbursement compliance for GI practices and ambulatory surgical centers.

Gastroenterology coding involves detailed understanding of Colonoscopy, Esophagogastroduodenoscopy (EGD), ERCP procedures, polypectomy techniques, biopsy reporting, and therapeutic endoscopic interventions. The FGEC™ Fellowship provides structured, case-based training focused on coding accuracy, modifier precision, and audit-ready documentation practices.

This fellowship covers:

Accurate assignment of CPT® Digestive System codes (40490–49999)

Coding for Colonoscopy with biopsy, polypectomy, and lesion removal

Differentiating screening vs diagnostic colonoscopy billing rules

Coding for EGD, ERCP, dilation, stent placement, and bleeding control

Proper application of Modifiers (26, 52, 53, 59, 51, 33) in GI procedures

Understanding Global Surgical Package and multiple procedure rules

Compliance with NCCI Edits and bundling regulations

Documentation validation for medical necessity and preventive service coverage

Preventing overcoding, downcoding, and improper unbundling

The FGEC™ – Fellowship in Gastroenterology Coding goes beyond basic CPT and ICD-10-CM code selection. It emphasizes clinical documentation interpretation, procedural coding precision, and reimbursement optimization in high-volume endoscopic environments.

This program is ideal for:

Gastroenterology Medical Coders

ASC and Endoscopy Coding Professionals

Revenue Cycle Specialists

Coding Auditors

Specialty Practice Consultants

With increasing scrutiny on screening colonoscopy coverage rules, anesthesia billing coordination, and endoscopic modifier usage, advanced gastroenterology coding knowledge is essential for compliance and financial performance.

The FGEC™ Fellowship by PMBAUSA LLC prepares professionals to confidently code complex digestive system procedures, interpret operative and endoscopy reports accurately, and maintain audit-ready claims submission standards.

This fellowship serves as a strategic pathway for coders seeking specialization in Gastroenterology Coding, Endoscopic Procedure Coding, and Specialty Revenue Cycle Compliance.

Course Objectives

The objective of the FGEC™ – Fellowship in Gastroenterology Coding is to develop advanced expertise in Gastroenterology Medical Coding, endoscopic procedural documentation analysis, and specialty reimbursement compliance within GI practices and ambulatory surgical centers.

By the end of this fellowship, participants will be able to:

  • Interpret and apply CPT® Digestive System codes (40490–49999) accurately

  • Assign correct ICD-10-CM diagnosis codes supporting medical necessity

  • Differentiate between Screening and Diagnostic Colonoscopy billing rules

  • Code complex procedures including Colonoscopy, EGD, ERCP, Polypectomy, and Stent Placement

  • Apply appropriate CPT® Modifiers (26, 52, 53, 59, 51, 33) in GI scenarios

  • Understand and implement Global Surgical Package rules in endoscopic services

  • Ensure compliance with NCCI Edits and bundling regulations

  • Interpret endoscopy and operative reports for precise code selection

  • Prevent overcoding, downcoding, and improper unbundling risks

  • Validate documentation for medical necessity and preventive service compliance

  • Analyze reimbursement impact within high-volume GI procedural settings

  • Strengthen audit readiness and compliance integrity in gastroenterology claims

This fellowship is designed to elevate professionals into Gastroenterology Coding Specialists with strong procedural, diagnostic, and compliance proficiency.

Colonoscopy Coding

What is a Colonoscopy?

It is an examination of the entire colon, from the rectum to the cecum, and may include examination of the terminal ileum or small intestine proximal to an anastomosis.

Place importance on scope length and type.

Anus (up to 5 cm of insertion),

Assign anoscopy code: 46600 to 46615

 

Anal canal, rectum and the sigmoid colon (6-25 cm),

Assign proctosigmoidoscopy code: 45300 to 45327

 

Entire rectum, sigmoid colon, and/or performs an exam of a portion of the descending colon up to the splenic flexure (26-60 cm),

Assign sigmoidoscopy code: 45330 to 45350

Sigmoidoscopy

  • Proctosigmoidoscopy involves examination of the rectum and may also include evaluation of a portion of the sigmoid colon.

  • Sigmoidoscopy involves examination of the entire rectum and sigmoid colon and may extend into a portion of the descending colon.

  • Colonoscopy involves examination of the entire colon, beginning at the rectum and extending to the cecum. It may also include inspection of the terminal ileum or a segment of the small intestine proximal to an anastomosis.

  • Colonoscopy through a stoma involves examination of the colon starting at a colostomy stoma and extending to the cecum or to a colon to small intestine anastomosis. This procedure may also include evaluation of the terminal ileum or proximal small intestine.

 

RAC Audit Hotspots in Gastroenterology Coding

Recovery Audit Contractors (RACs)

Recovery Audit Contractors, commonly known as RACs, play a critical role in safeguarding the financial integrity of the Medicare Fee for Service FFS program. The primary mission of the Medicare Recovery Audit Program is to identify, correct, and prevent improper Medicare payments across all 50 states.

RACs focus on the efficient detection and recovery of overpayments made for healthcare services provided to Medicare beneficiaries. At the same time, they also identify underpayments to ensure providers are reimbursed accurately. The ultimate goal of the program is not only payment recovery, but also systemic improvement, enabling CMS and Medicare Administrative Contractors to implement corrective actions that reduce future improper payments.

What Does a Recovery Audit Contractor Do

Recovery Audit Contractors review Medicare claims on a post payment basis. Their responsibility is to analyze previously paid claims and determine whether payments were made correctly according to Medicare coverage policies, coding guidelines, documentation requirements, and billing regulations.

When improper payments are identified, RACs initiate the recovery of overpayments and report findings to CMS. These findings help CMS, Carriers, Fiscal Intermediaries, and Medicare Administrative Contractors improve payment accuracy, strengthen compliance controls, and reduce recurring errors in billing and documentation.

Esophagoscopy, Upper GI Endoscopy, and Enteroscopy

Esophagoscopy, Upper GI Endoscopy, and Enteroscopy

• Esophagoscopy – limited to study of the esophagus.

• Esophagogastroduodenoscopy (EGD) - including study of the esophagus, stomach, and either the duodenum and/or jejunum

• Enteroscopy- complete study of the upper GI tract, past the second portion of the duodenum and/or including the ileum

 

Lower GI Endoscopy

• Ileoscopy- scope is inserted through ileostomy (stoma on abdominal wall)

• Pouchoscopy- scope can be inserted via anus or abdominal pouch directly into small intestine

• Anoscopy- anoscope inserted and anus is visualized

• Sigmoidoscopy- flexible sigmoidoscope inserted and anus, rectum and sigmoid colon are visualized

• Colonoscopy- colonoscope is inserted and entire colon and terminal ileum is visualized

• Colonoscopy thru stoma- scope is inserted through colostomy (stoma on abdominal wall)
