Hard cutover: all home-health service billing must be transmitted via HHAeXchange. Missing or incomplete EVV records prevent a claim from even being created.

Edit-rate / usage rule
Michigan pairs a 15% manual-edit expectation with something stricter than a denial: from 2026, an incomplete EVV record means the claim cannot be created at all.
Claim-creation gating changes the failure mode
In most states, an EVV mismatch produces a denial you can see, work, and resubmit. Michigan's 2026 model moves the gate earlier: billing flows through the state EVV system itself, so a visit with missing or incomplete EVV data never becomes a claim. The failure is silent — no remittance code, just revenue that never bills.
That makes the discipline states like Missouri preach mandatory in Michigan: reconcile visits to Verified status before your billing cycle, every cycle, because the system will no longer let unverified work even enter the queue.
Using the soft-launch window
The period since September 2024 has been Michigan's practice window — the same function Missouri's N363 alerts and Ohio's MyCare warnings served. Every visit that needs manual completion today is a claim that won't exist in the hard-cutover world. Fixing clock-in behavior and exception backlogs now is the whole game.
