If, in the opinion of the treating physician, more frequent treatments are necessary, the physician may obtain written prior authorization from the MOH. Authorization will be dependent on the physician demonstrating that the increased frequency of the service is generally accepted as necessary for the patient under the circumstances.

G236 is only eligible for payment same patient same day with other nerve block and/or injection services if rendered to diagnose or treat a separate condition.

The sympathetic block that may result from epidural, spinal, plexus and peripheral nerve blocks is not payable as G920, G234 or G236.
