G374 – I.V. regional guanethidine
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Intravenous (I.V.) regional guanethidine is a therapeutic procedure categorized under the 'Miscellaneous' sub-category within 'Interventional Pain Injections'. This service involves the specialized administration of guanethidine via an intravenous route to a specific region of the body.
When to Use
- Use G374 for the administration of intravenous regional guanethidine specifically for the management of complex regional pain syndrome (CRPS).
- Select this code when performing a sympathetic block via the intravenous route rather than the paravertebral approach used for G920 or G234.
Common Pitfalls
- Billing G374 on the same day as G920, G234, or G236 without clear documentation of a separate clinical condition will result in automatic rejection.
- Attempting to bill G374 as a standard intravenous infusion procedure code will lead to audit flags, as it is strictly defined for regional sympathetic blockade.
Billing Tips
- Ensure your chart notes explicitly distinguish the anatomical site and the distinct pathology if you are billing G374 alongside other nerve block codes like G232 or G233.
