Where home-care margin leaks: unbilled hours, EVV clawbacks, and rate mismatches.

The five places margin disappears

Authorized but unbilled hours. The most common leak is also the quietest. Care is scheduled, delivered, and paid to the caregiver, but the handoff from scheduling to billing never completes. There is no denial, no remittance line, no alert. The visit is fully recoverable if it is caught before the timely filing window closes; after that, the entitlement is gone.

Lapsed authorization windows. Authorizations have end dates. Visits keep flowing on the schedule after the end date because nothing on the calendar surfaces it. Every claim after the lapse denies. Some payers will grant a retroactive authorization if you move fast and document why service continued; most will not once you are past their window.

EVV gaps and clawback exposure. EVV has been mandatory under the 21st Century Cures Act. App failures, GPS drift, caregivers clocking from an unexpected location, and EMR-to-EVV sync mismatches all produce records that look non-compliant on audit. Some payers deny at submission, some pay and later recoup. The fix lives upstream in daily or weekly reconciliation, not at appeal.

Rate and modifier mismatches. Multi-tier contracts, live-in modifiers, program-specific codes, and payer fee-schedule updates all conspire to produce claims that either deny outright on the wrong code or, worse, pay silently below the contracted rate. Silent underpayments do not show up as denials, so they stay invisible until someone divides paid dollars by billed units and compares against the contract.

Denied claims left unworked. Few agencies work every denial in-window. Larger and newer denials get attention; smaller and older ones fall through. Once the appeal window closes, the money is not recoverable at any price. A denial log with nothing in the last 60 days is usually not clean, it is usually abandoned.
