Explanation

Updated October 26, 2026

P9 is the Ministry's 'Complex New patient' message. It relates to the Health Care Connect complex/vulnerable new patient fee.

What it means

The Ministry describes code P9 only as "Complex New patient". It appears on the Remittance Advice next to a payment line.

It most likely relates to the Health Care Connect complex/vulnerable new patient fee (Q053A). That fee is a one-time payment for enrolling a patient whom Health Care Connect has registered as complex/vulnerable, within three months of registration (Appendix Q, AQ2).

How to fix it

  1. Check the amount paid on the line that carries P9.
  2. If it was paid as expected, there is nothing to do.
  3. If you expected a different amount, check that the patient was registered with Health Care Connect as complex/vulnerable and enrolled with you within three months. If you believe the payment is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details.

Don't resubmit if

  • The claim is already on your Remittance Advice. Use an RAI, not a new claim.
