Oncu — a Vanguard Veil Limited company

For home-care agencies

Prove EVVcompliancebefore the state asks.

Every broken visit found, fixed, and evidenced — from the export you already run.

Since March 2025, Ohio Medicaid denies any claim with no matching EVV visit.Five exception types priced in dollars, from your own rates.One text to the caregiver who can fix it. Consent-gated.An audit log nobody can edit — not even us.

Start free — make an account and upload your own export. Snapshot — we run it for you and walk you through what it finds, within 48 hours.

Reads the export you already produce

Any EVV system · Any state

CSV or XLSX, exactly as your aggregator exports it. Oncu matches your columns by name rather than expecting one vendor’s layout, so a different aggregator or a different state is a mapping change, not a rebuild. Send us a sample export and we’ll confirm it reads before you commit to anything.

One week, one upload

One week, through the engine.

Real output from the same engine your export would run through, on a fictional agency’s visits — one week, generated. The product tour runs a separate generated dataset, so its figures aren’t comparable with these.

The sample is the real product on an invented agency, with every write switched off. Nothing in it is anyone’s data.

Why this exists

A visit you can’t proveis a visit you don’t get paid for.

Oncu reads the export you already produce, prices every claim at risk from your own rates, and texts the one person who can fix it — the caregiver.

An audit log nobody can edit.

The five ways a claim dies.

Checked on every visit, every upload.

  • Missing clock-out

    The visit has no end time — the most common one, and usually a late shift nobody closed.

  • Missing clock-in

    No start time either, so there is nothing to verify the visit against.

  • Missing service code

    Nothing to bill it against, so the claim has no line to sit on.

  • Client won't match

    The recipient ID on the visit isn't one of yours — a digit out, usually.

  • Caregiver won't match

    The name on the visit isn't on your roster, or is on it three different ways.

Each one is priced against your own rates, so the list arrives in dollars rather than as a count — and each goes to the caregiver who can fix it.

Product tour

Every screen, in the order you’d touch them.

Creating the account, the agreement, the roster, an export going in, the five checks running, the text to the caregiver, and the week after. Recorded against an invented agency; every figure in it is unmodified engine output.

Questions

Answers before you ask.

Do we have to change our EVV system?

No. Oncu reads the export your EVV system already produces, whichever system that is. You send us the file you already generate; we never write to your source system and never modify a source row.

How long does setup take?

Minutes, not an IT project. Create your account, accept the Business Associate Agreement, upload your caregiver roster and your first EVV export. Exceptions appear immediately.

What exactly do caregivers receive?

A short, PHI-free text about their own visit — for example, that a visit is missing a clock-out. Never a client name, address, or any care detail. Reminders are rate-limited to a single gentle nudge and sent only during quiet-hours-compliant windows. Reply STOP at any time.

Is our data secure, and is this HIPAA-compliant?

A Business Associate Agreement is included and must be accepted before any real data is uploaded. Every record is scoped to your agency and enforced by database row-level security, protected health information never leaves the platform in a message, and every action lands in an append-only audit log.

What happens if we cancel?

Cancel any time from the billing portal — you keep access through the end of the period you've paid for, plus a 30-day window to export your data. No cancellation fee.

Do you support our state?

Any of them, in principle. Oncu matches your export's columns by name rather than expecting one vendor's layout, and per-agency mappings handle anything unusual — so a different aggregator or a different state is a configuration change, not a rebuild. Send us a sample export and we'll confirm it reads before you commit to anything.

Still have a question? Ask it on the readout call.
