G238 – Transverse scapular nerve
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
G238 is a diagnostic and therapeutic procedure for a nerve block injection of the transverse scapular nerve. This procedure is listed in the 'NERVE BLOCKS - PERIPHERAL/OTHER INJECTIONS' subcategory of the Schedule of Benefits. A 50% premium (E958) can be added if alcohol or other sclerosing solutions are used.
When to Use
- Use G238 for targeted suprascapular nerve blocks in patients with chronic shoulder pain or adhesive capsulitis when diagnostic or therapeutic relief is required.
- Select G238 when performing a peripheral nerve block specifically for the transverse scapular nerve, distinct from general trigger point injections like G372 or G373.
Common Pitfalls
- Billing G238 in addition to a surgical procedure performed on the same site is prohibited, as the nerve block is considered part of the surgical fee.
- Attempting to bill for ultrasound or fluoroscopic guidance alongside G238 will result in a rejection, as imaging fees are explicitly excluded for this code category.
- Submitting G238 with a physical assessment code without ensuring the procedure is distinct and separately payable, though G238 is generally eligible for concurrent billing.
Billing Tips
- Always append E958 to G238 if you are using alcohol or sclerosing agents to capture the mandatory 50% premium for the procedure.
