What this reference tells you

AC1 is an Error Report rejection condition. It helps identify why a claim failed initial processing so the underlying data or documentation can be reviewed.

Suggested review path

Review frequency and maximum-payment rules; use an alternate FSC only when the clinical record supports it.

Before using this code

Confirm the current Ministry publication, the patient and provider context, the date of service, and documentation supporting the claim. A searchable reference does not establish eligibility or guarantee payment.
