What North Carolina requires
Oct 1, 2025
Hard launch for managed-care home-health EVV: claims for dates of service on or after this date without required EVV data are denied.

Structure
North Carolina runs one of the most layered EVV setups in the country — three aggregators (Sandata, HHAeXchange, CareBridge), each tied to a different payer type.

Billing trap
Home-health claims must be billed under taxonomy code 251E00000X, or the claim is denied outright.

Manual-entry line
Up to 15% of visits may be entered manually when EVV genuinely can't capture them; the state monitors the percentage and overuse invites a Program Integrity audit.

Edit-rate / usage rule
North Carolina monitors manual entry around a 15% line and hard-denies home-health claims lacking EVV data. Overusing manual entry is treated as an audit signal, not a workaround.
The multi-aggregator trap
With three aggregators mapped to different payer types, the most common North Carolina failure isn't a missing visit — it's a visit sent to the wrong pipe. Caregivers clocking in through the wrong app for that payer, or agencies routing claims directly to a payer instead of through the assigned aggregator, produce denials with perfectly real visits behind them.
The fix is an assignment map: every client mapped to payer, payer mapped to aggregator, aggregator mapped to the app the caregiver must use. Most NC denial clusters trace to one row of that map being wrong.
Two mechanical traps worth pinning to the wall
Taxonomy 251E00000X on every home-health claim — the wrong taxonomy denies regardless of how clean the EVV record is. And schedule-versus-actual mismatches (plan says four hours, EVV shows three and a half) caught many agencies at the October 2025 hard launch: bill what the visit verified, not what the plan scheduled.
