E988 – Extracranial stent with endovascular thrombectomy
OHIP Surgical Assists Code · Schedule of Benefits
An add-on fee for the deployment of an extracranial stent during an endovascular thrombectomy (EVT) for acute ischemic stroke secondary to large vessel occlusion.
When to Use
- Use E988 when you deploy an extracranial carotid stent to facilitate access or treat tandem lesions during an N131 endovascular thrombectomy procedure.
- Apply this code specifically when the stent is placed in the extracranial vasculature, distinguishing it from intracranial stenting which requires E987.
Common Pitfalls
- Billing E988 alongside E987 for the same session is prohibited, as both are restricted to a single payment per N131 encounter.
- Submitting E988 with any 'X' or 'J' prefix service codes will result in automatic rejection due to the strict operative session exclusivity rules.
- Attempting to bill for imaging interpretation in conjunction with N131 and E988 will trigger a rejection, as all imaging is considered bundled into the primary procedure.
Billing Tips
- Ensure E988 is submitted strictly as an add-on to the primary N131 code to avoid claim processing errors.
- Document the specific anatomical location of the extracranial stent clearly to justify the use of E988 over the intracranial E987 code during an audit.
