- Select Z941 instead of N530 or N531 when the procedure is specifically a diagnostic stimulation trial rather than a therapeutic nerve block or injection.
Common Pitfalls
- Billing Z941 alongside Z942 or Z943 for the same anatomical site on the same day will trigger a rejection for duplicate or overlapping services.
- Failure to include the appropriate surgical assistant suffix (B) or anaesthetist suffix (C) will result in payment errors for the supporting team members.
Billing Tips
- Ensure that any applicable After Hours Procedure Premiums are applied to Z941 if the procedure meets the specific time-of-day eligibility criteria defined in the Schedule.
