Certified Gastroenterology Coder (CGIC)
Advance your gastroenterology coding career with the CGIC certification.What is a Certified Gastroenterology Coder?
The CGIC credential validates a medical coder’s advanced expertise in gastroenterology coding. Earning the CGIC demonstrates proficiency in ICD-10-CM, CPT®, and HCPCS Level II coding specific to gastrointestinal diseases, diagnostic testing, and endoscopic procedures, all in compliance with current coding guidelines and payer requirements.
This certification is ideal for professional coders working in gastroenterology practices, ambulatory endoscopy centers, multispecialty groups, and hospitals. CGIC-certified coders are equipped to ensure accurate reimbursement, minimize compliance risk, and address the unique challenges of coding for both diagnostic and therapeutic GI procedures.
Why earn the CGIC certification?
Stand out with a specialty credential recognized by gastroenterology practices, hospitals, and healthcare organizations
Validate your ability to accurately code diagnostic tests, screenings, and therapeutic procedures of the gastrointestinal tract
Gain deeper understanding of payer-specific guidelines, bundling edits, and modifier use unique to GI services
Position yourself for advanced career opportunities in gastroenterology coding, auditing, and compliance

Maintaining your certification
To maintain your CGIC credential, you must maintain your AAPC annual membership. You must also earn 36 continuing education units (CEUs) every two years, 8 of which must be gastroenterology specific.
Elevate your career with the CGIC.
Becoming a CGIC-certified medical coder demonstrates your commitment to accuracy, compliance, and excellence in one of the most procedure-driven specialties in healthcare. Whether you want to advance your career, specialize in gastroenterology coding, or help your organization achieve precise reimbursement and audit readiness, the CGIC is your pathway to professional growth and recognition in GI coding.
Specialty Revenue Cycle Training
Protecting revenue takes more than one certified coder.
Specialty coding leaves little room for error. As AI-driven documentation and coding tools raise the bar for oversight, even small misses in high-value specialties can lead to denials, revenue leakage, or audit risk.
AAPC's Specialty Revenue Protection Program helps coding and CDI teams build deeper specialty knowledge and apply it consistently, across gastroenterology, cardiology, E/M, musculoskeletal, and more.
