What it means on your remittance
The person you billed for does not exist in your EVV account as far as the payer can tell. In Ohio's published guide this fires when the Recipient Medicaid ID on the claim isn't in your Sandata account — either the client was never added, or the ID on the visit is wrong (an 'Unknown Recipient' visit also lands here).
Why it happens
- The client was never added to your EVV account — new admissions are the classic case.
- The Recipient Medicaid ID on the visit record is wrong (one digit off is enough to break the match).
- A visit was recorded without a recipient name or ID and is sitting flagged as an 'Unknown Recipient' in the EVV system.
- Ohio AGE programs: the client's record uses the wrong identifier — state-funded recipients need their PASSPORT ID in the EVV system until a Medicaid ID is issued.
How to fix it, step by step
- 1Open your EVV system and search for the client on the denied claim — by name and by Medicaid ID separately, since one may be right and the other wrong.
- 2If the client is missing, create the recipient record with the exact Medicaid ID that appears on your claims.
- 3If the client exists, compare the ID digit by digit against the claim; correct whichever is wrong. Deactivate any duplicate or incorrect recipient records.
- 4Check your exception queue for 'Unknown Recipient' visits and attach them to the right client.
- 5Re-verify the affected visits, confirm they reach the aggregator, and resubmit.
How to tell it apart
N819 is specifically about the PERSON not matching. If the client matches but the service doesn't, Ohio uses 272+N56; if the units don't, N820. The official X12 text — 'patient not enrolled in Electronic Visit Verification system' — makes this one EVV-specific everywhere, not just in Ohio.
The bigger picture
Onboarding is the choke point: agencies that add the EVV recipient record as a formal step of client intake almost never see N819. Agencies that let the first visit happen before the client is in the system see it constantly.

What does denial N819 mean?
The person you billed for does not exist in your EVV account as far as the payer can tell. In Ohio's published guide this fires when the Recipient Medicaid ID on the claim isn't in your Sandata account — either the client was never added, or the ID on the visit is wrong (an 'Unknown Recipient' visit also lands here).
How do I fix a N819 denial?
Add the client to your EVV system with the exact Medicaid ID used on claims, or correct the ID on the existing record. Resolve any 'Unknown Recipient' visits. Ohio AGE programs: use the client's PASSPORT ID until their Medicaid ID is issued. Then re-verify the visit and resubmit.
The client is right there in my EVV portal — why did the claim still deny?
Match failures are exact. If the EVV record has the client under a slightly different Medicaid ID than the claim (a typo, an old ID, a PASSPORT-vs-Medicaid mixup in Ohio AGE programs), the payer sees two different people. Compare the IDs character by character.
