The authorization-to-claim gap: where home-care revenue quietly disappears.

Most revenue loss in home care does not announce itself. A denial at least shows up on a remittance — you can see it, work it, and rebill it. The more dangerous loss is the kind that never generates a denial at all: the authorized hour that was delivered but never billed, the claim that paid a few dollars under the contracted rate, the authorization that lapsed three visits before anyone noticed. None of it lands in a denial queue. It just quietly fails to become revenue.

That is the authorization-to-claim gap. It lives in the space between four numbers that should match and almost never do: hours authorized, hours delivered, hours billed, and dollars actually paid. This guide is about how that gap opens, why it tends to stay open, and what it takes to close it before the money is gone for good.

Four numbers that should agree

Walk a single member's care through the billing cycle and you can see where the numbers drift apart:

• Hours authorized. The payer approves a set number of units, under specific codes, for a specific date range. This is the ceiling on what can be billed.
• Hours delivered. Caregivers provide care — sometimes exactly to the authorization, often a little under, occasionally over. Visits get missed, covered late, or split across caregivers.
• Hours billed. The claim goes out. Ideally it reflects every delivered, authorized hour. In reality, some delivered hours never make it onto a claim — a visit that did not sync, a unit that got dropped, a member whose authorization had quietly changed.
• Dollars paid. The remittance comes back. Some lines pay in full, some deny, and some pay — but at less than the contracted or authorized amount.

Every place two of those numbers fail to line up is a potential leak. And because most of these leaks never produce a denial, they are invisible to a billing process that only works the denial queue.

Why the gap stays open: timely filing

What makes the authorization-to-claim gap so costly is that it is governed by a clock. Federal rules under 42 CFR § 447.45 set an outer limit of 12 months for Medicaid claim filing, but states routinely enforce shorter windows — often 90, 120, or 180 days — and managed-care plans frequently set tighter deadlines still. Once a claim passes its timely-filing window, the right to that money is generally gone, no matter how legitimate the service was.

That is the trap. An unbilled authorized hour or an underpaid line does not raise an alarm. It sits, undetected, while the filing clock runs. By the time a routine review catches it — if one ever does — the window has often already closed. The gap does not just cost money; the deadline makes the loss permanent.

The shapes the gap takes

In practice, the authorization-to-claim gap shows up as a handful of recurring patterns:

• Unbilled authorized hours. Care that was authorized and delivered but never made it onto a claim — the purest form of the gap.
• Units delivered over authorization. Hours provided beyond what was approved, which deny or get clawed back — a sign the authorization was not tracked against delivery in real time.
• Authorization drift. A claim whose code, units, or dates fall outside the current authorization because the authorization changed and the billing did not follow.
• Silent underpayments. Lines that pay below the contracted or authorized rate. Because they pay something, they never appear as a denial — they only surface when payment received is compared, line by line, to payment expected.
• Lapsed authorizations. Continued service after an authorization expired, where the renewal was late or missed, turning delivered care into unbillable care.

The common thread is that none of these are care problems. The caregivers did the work. The loss is entirely in the administrative layer — in whether anyone reconciled the authorization against the delivery, the claim, and the payment while there was still time to act.

How agencies close the gap

Closing the authorization-to-claim gap means reconciling those four numbers continuously rather than trusting that what was scheduled got billed and what was billed got paid. Concretely, that is comparing authorizations against delivered visits to catch unbilled and over-authorization hours, comparing claims against authorizations to catch drift, and comparing payments received against payments expected to catch the silent underpayments — all while there is still filing time to recover what is recoverable.

This is exactly the reconciliation Reeve performs. It sits read-only over whatever EMR an agency already runs and lines up authorizations, delivered visits, claims, and remittances, surfacing every place they fail to agree, ranked by recoverable dollars and by how much filing time is left. For the tracking side specifically, see home-care authorization tracking. For how denials fit alongside the silent losses, see home-care claim denials and recovery, and for the full map, where home-care margin leaks.

The takeaway for operators

The denial queue is the part of revenue loss you can see, and most agencies work it well. The authorization-to-claim gap is the part you cannot see, and it is often larger — because it never raises a flag and the filing clock quietly turns it permanent. Agencies that protect their margin reconcile authorized, delivered, billed, and paid against one another continuously, and they act inside the filing window. The money you earned but never collected is still yours, right up until the deadline says it is not.
