Arizona home-care margin recovery: the state that built its own EVV aggregator.

Arizona is the state to watch on EVV right now, because in late 2025 it did something none of its peers did. For years, AHCCCS — Arizona's Medicaid agency — ran EVV through Sandata as both the statewide vendor and the aggregator, in an open model where agencies could use Sandata or an alternate vendor that fed the Sandata aggregator. On October 1, 2025, that changed. AHCCCS stopped using Sandata and stood up its own in-house AHCCCS EVV Aggregator. Providers now contract with an EVV vendor of their choice, at their own cost, and that vendor sends data directly to the state.

For an attendant-care agency billing 15-minute units on thin margin, that shift matters in a very concrete way: your claims now have to match a Verified visit in the state's own aggregator, and the cost and responsibility of keeping that pipeline clean moved onto you.

EVV 2.0: matching the state's own system, at your cost

The mechanics of the October 2025 change are what create new margin risk. Under the old model, an alternate EVV vendor fed the Sandata aggregator. Under EVV 2.0, your vendor sends visit data directly to the AHCCCS-run aggregator instead. AHCCCS kept the same technical requirements vendors had to meet, but it made EVV vendor contracting and cost the provider's responsibility — "all providers are required to contract with an EVV vendor of their choice and are responsible for the cost" — and added new registration and a new EVV help desk.

The claim-matching rule survived the transition intact, and it is strict. Since the hard claim edits took effect November 1, 2022, an EVV-required claim does not pay unless all required EVV data is present and the claim matches a visit in the aggregator that is in Verified status. A visit that is merely captured but not Verified, or that fails to match the claim line, blocks payment. During the October 2025 cutover, AHCCCS even directed health plans to hold EVV-eligible claims for several days to avoid mass denials — a sign of how tightly claims are now coupled to the state aggregator.

Double jeopardy: the contractor authorization and the state edit

Arizona layers a second checkpoint on top of EVV, and the two together are where margin quietly disappears. ALTCS is administered by program contractors — managed-care plans, not AHCCCS directly. For the 2025 to 2028 contract cycle, four ALTCS plans operate across three geographic service areas: UnitedHealthcare Community Plan, Banner–University Family Care, Mercy Care, and Arizona Complete Health. Which plans you deal with depends on the county, so a multi-region agency is managing several contractors' authorization rules at once.

That matters because, in the EVV model, a member only appears in your account when tied to a prior authorization from the health plan, or through the AHCCCS Service Confirmation Portal when no auth is required. A missing or mismatched authorization is a documented cause of EVV visits not linking — and a visit that does not link cannot match the claim, so the claim denies. An attendant-care claim in Arizona therefore has to survive both the contractor's authorization and units and the AHCCCS hard EVV edit. A mismatch on either one denies payment on 15-minute-unit work, where denials erode margin directly.

Where the margin actually leaks in Arizona

• Unverified visits. Visits captured but not in Verified status at the AHCCCS aggregator — the service happened, but the claim has nothing to match against, so it denies.
• Authorization-link failures. Missing or mismatched contractor authorizations that stop a member's visits from linking, breaking claim matching downstream.
• Contractor rule variation. Four ALTCS program contractors across three service areas, each with its own authorization process — rules that are correct for one plan are wrong for another.
• EVV 2.0 transition fallout. Claims caught in the October 2025 cutover, or visits routed under the old Sandata flow that need re-checking against the new aggregator path.
• Silent underpayments. Claims that pay below the authorized or rate-correct amount, never flagged as a denial, visible only when payment received is reconciled against payment expected on 15-minute units.

None of these are visible from the scheduling view. They appear only when EVV visit status, contractor authorizations, claim lines, and remittances are reconciled against each other.

Why a read-only recovery layer fits Arizona

Reeve sits read-only over whatever EMR and EVV export an agency already runs — WellSky, AxisCare, HHAeXchange, AlayaCare, or any other system — and reconciles what was delivered against what each contractor authorized against what AHCCCS actually paid. For an Arizona agency, that means checking visit Verified status against claim lines, catching authorization-link failures before they cascade into denials, and surfacing the silent underpayments that a 15-minute-unit, four-contractor, new-aggregator environment produces.

Because Reeve is read-only and neutral across every EMR — and because the EVV-2.0 shift put the cost and responsibility of a clean pipeline squarely on the provider — a neutral layer that watches that pipeline for you is worth more in Arizona, not less. Reeve never writes to your billing workflow without your control and has no reason to overlook a finding that implicates any vendor or plan. It hands you a ranked list of recoverable dollars with the reason attached, and the ones still inside the filing window are the ones you can rebill now.

What the free Arizona Margin Teardown does

The way to find out whether unverified visits or authorization-link failures are draining your margin is to look — on a real, de-identified slice of your own data, before you spend a dollar. The Margin Teardown is a one-time, read-only read of where margin is leaking: the unverified visits, the link failures, and the underpayments. It is free, it is yours to keep whether or not you ever work with Reeve, and it carries the same 3×-or-free guarantee the rest of the engine does — if Reeve does not surface at least three times its monthly fee in recoverable margin you agree is real, you do not pay.
