Understanding GERD CPT Codes: A Comprehensive Guide for Healthcare Providers
Published on November 28, 2024
Key Takeaway
Proper use of GERD CPT codes is crucial for accurate billing and reimbursement in gastroesophageal reflux disease management.
Introduction
Gastroesophageal reflux disease (GERD) is a common condition affecting millions worldwide. As healthcare providers, understanding the proper use of Current Procedural Terminology (CPT) codes for GERD-related procedures is crucial for accurate billing and reimbursement. This comprehensive guide will explore the essential GERD CPT codes, their applications, and best practices for healthcare providers.
Common GERD CPT Codes
Here are some of the most frequently used CPT codes for GERD-related procedures:
- 43235: Upper gastrointestinal endoscopy, diagnostic
- 43236: Upper GI endoscopy with biopsy
- 43239: Upper GI endoscopy with biopsy of esophagus, stomach, or duodenum
- 43248: Upper GI endoscopy with insertion of guidewire followed by dilation of esophagus
- 91038: Esophageal function test with prolonged pH recording
Diagnostic Procedures for GERD
Accurate diagnosis is crucial for effective GERD management. Fock et al. (2010) note that there is no standard criterion for GERD diagnosis, and 24-hour pH monitoring lacks sensitivity in non-erosive reflux disease (NERD). However, several diagnostic procedures have corresponding CPT codes:
- 91034: Esophagus, gastroesophageal reflux test; with nasal catheter pH electrode(s) placement, recording, analysis and interpretation
- 91035: Esophagus, gastroesophageal reflux test; with mucosal attached telemetry pH electrode placement, recording, analysis and interpretation
- 91037: Esophageal function test, gastroesophageal reflux test with nasal catheter intraluminal impedance electrode(s) placement, recording, analysis and interpretation

Treatment Procedures and Associated CPT Codes
Treatment for GERD often begins with lifestyle modifications and medications. However, some patients may require more advanced interventions. Subramanian et al. (2015) suggest that patients with partial response to proton pump inhibitors (PPIs) can be treated surgically or using emerging endoscopic therapies. Here are some relevant CPT codes for GERD treatments:
- 43257: Upper GI endoscopy with delivery of thermal energy to the muscle of lower esophageal sphincter and/or gastric cardia
- 43280: Laparoscopy, surgical, esophagogastric fundoplasty (e.g., Nissen, Toupet procedures)
- 43281: Laparoscopy, surgical, repair of paraesophageal hernia, includes fundoplasty, when performed; without implantation of mesh
- 43282: Laparoscopy, surgical, repair of paraesophageal hernia, includes fundoplasty, when performed; with implantation of mesh
Best Practices for GERD CPT Coding
To ensure accurate billing and optimal patient care, consider these best practices:
- Document thoroughly: Clearly record all symptoms, diagnostic findings, and treatment decisions to support your CPT code selection.
- Stay updated: Regularly review CPT code updates and guidelines to ensure compliance with the latest standards.
- Use modifiers appropriately: Apply modifiers when necessary to indicate multiple procedures or special circumstances.
- Coordinate with billing staff: Maintain open communication with your billing department to address any coding questions or issues promptly.
- Conduct periodic audits: Regularly review your GERD-related coding practices to identify areas for improvement and ensure consistency.

Conclusion
Proper use of GERD CPT codes is essential for accurate billing, reimbursement, and quality patient care. By familiarizing yourself with common GERD-related CPT codes, understanding their applications, and following best practices, you can ensure that your practice maintains compliance while providing optimal care for patients with gastroesophageal reflux disease. Remember to stay informed about coding updates and continue to refine your documentation and coding processes to support the best possible outcomes for your GERD patients.
