E816 – ERCP with electrohydraulic lithotripsy for choledocholithiasis
OHIP Surgical Assists Code · Schedule of Benefits
Endoscopic retrograde cholangiopancreatography (ERCP) with electrohydraulic lithotripsy for choledocholithiasis
When to Use
- Use E816 when a large or impacted bile duct stone cannot be cleared using standard balloon or basket extraction during an ERCP procedure coded as Z558.
- Apply this code when electrohydraulic lithotripsy is specifically required to fragment a stone that has proven refractory to mechanical lithotripsy or standard extraction attempts.
Common Pitfalls
- Billing E816 without a corresponding primary ERCP code like Z558 or Z561 will result in an automatic rejection.
- Submitting E816 for routine stone extraction where standard mechanical methods were not first attempted or documented as failed is a common audit trigger.
Billing Tips
- Ensure your operative report explicitly documents the failure of standard extraction techniques to justify the medical necessity of the electrohydraulic lithotripsy add-on.
