G239 – Differential intrathecal spinal block
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Differential intrathecal spinal block. This service is classified under Diagnostic and Therapeutic Procedures, specifically within the interventional pain injections category. The service involves the injection of medication into the intrathecal space to help diagnose the source of pain.
When to Use
- Use G239 when performing a diagnostic differential spinal block to isolate the specific pain pathway in patients with complex chronic pain syndromes.
- Select G239 when the procedure is performed as a standalone diagnostic intervention, distinct from any surgical or therapeutic procedure performed by the same physician on the same day.
Common Pitfalls
- Billing G239 in conjunction with a surgical procedure performed by the same physician will trigger an automatic rejection under GP100, as the block is considered an inclusive component of the main procedure.
- Attempting to add after-hours premiums (E409, E410, E412, E413) or trauma premiums (E420) to G239 will result in payment denial, as this code is not designated as a Major Invasive Procedure.
Billing Tips
- Ensure the clinical record clearly distinguishes the diagnostic intent of the G239 block from any therapeutic injections, as the Ministry strictly monitors for unbundling of diagnostic and therapeutic services.
