Invalid SEAMO Provider Code

Explanation

Updated October 26, 2026

VS1 means the SEAMO provider code on a SEAMO claim isn't valid. Correct it with the value your SEAMO setup expects and resubmit.

What it means

VS1 is one of a group of error codes (VS1 to VS6) for SEAMO claims. The Ministry lists it only as "Invalid SEAMO Provider Code".

SEAMO is the Southeastern Ontario Academic Medical Organization, one of the alternate funding arrangements named in the Schedule's Appendix Q. Its claims carry extra fields that ordinary fee-for-service claims don't.

How to fix it

  1. Check the SEAMO provider code on the claim against the values set up for your SEAMO billing.
  2. Correct it and resubmit.
  3. If you are not sure which value is valid, ask the people who manage SEAMO billing for your department.

Don't resubmit if

  • The SEAMO provider code has not been changed.
