Payer IDs can differ between clearinghouses (Availity, Waystar, Office Ally, Trizetto, etc.) and by product line. Confirm this ID against your clearinghouse's payer list before submitting.

Routing notes for billers

VA CCN claims go to the network administrator, not the VA: Optum handles regions 1–3 (commonly listed as VACCN), TriWest handles 4–5. Confirm the veteran's region before submitting.

If claims to this payer go missing

Misrouted claims surface as CO-109 denials or remark N418 — and meanwhile the filing clock keeps running. Keep your clearinghouse acceptance reports as proof of original submission; they usually restart the clock on appeal.

OakClaim routes every claim right the first time.
