E629 – Endoscopic placement of stent in duodenum
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E629 when performing a palliative duodenal stent placement for malignant gastric outlet obstruction during an OGD (Z399 or Z400).
- Use E629 when placing a stent to manage a benign duodenal stricture or fistula during a diagnostic duodenoscopy (Z560).
Common Pitfalls
- Billing E629 as a standalone service will result in an automatic rejection; it must be submitted on the same claim as the primary endoscopic procedure.
- Failing to link the stent placement to the primary procedure code can lead to audit flags if the primary procedure is not clearly identified as the base for the add-on.
- Attempting to bill E629 for esophageal or colonic stenting, as this code is strictly restricted to duodenal placement.
Billing Tips
- Ensure the primary procedure (e.g., Z399) is listed first on the claim, followed by E629, to ensure the system recognizes the add-on relationship.
- If the procedure is performed after hours or for trauma, apply the relevant premiums (E409, E410, or E420) to the primary procedure fee, as E629 is an add-on that typically follows the base procedure's eligibility for these premiums.
