EVV in Oklahoma: Aggregator, Approved Vendors, Reason Codes and Deadlines (2026)

Oklahoma Medicaid EVV explained for home care agencies: AuthentiCare for fee-for-service, HHAeXchange for SoonerSelect plans, the planned move to Acumen, open model, rounding, reason codes and how to fix a denied claim.

November 5, 2026

Short answer. Oklahoma runs an open EVV model. The Oklahoma Health Care Authority (OHCA) uses AuthentiCare, from Fiserv, for fee-for-service programs such as the ADvantage waiver and State Plan Personal Care; providers serving SoonerSelect health plan members use HHAeXchange. OHCA has awarded its next EVV contract to Acumen Fiscal Agent, with no final transition date yet. Check a visit before billing with the EVV visit checker.

Which vendors are approved in Oklahoma?

OHCA rules let providers use the designated statewide system or their own EVV-compliant system, as long as the data comes from an OHCA-authorized and approved system or aggregator. For SoonerSelect members, HHAeXchange accepts other EVV systems after an integration attestation and an API ticket. OHCA hasn’t published a list of approved third-party systems, so confirm with evv@okhca.org before your first Medicaid visit.

Open or closed model, and what it means for you

Open: caregivers clock in and out in the state system or an approved alternative, the visit reaches the state, and the claim is matched against it. SoonerCare will not pay a claim unless the visit data comes from an approved system.

The six elements every visit must carry

Type of service, individual receiving the service, individual providing the service, date, location, and start and end time. Missing any one is a rejected visit. The usual failures: a missing clock-out, a caregiver not linked to the agency on that date, and a check-in away from the home with no reason recorded.

Rounding and units

Oklahoma rounds each visit to the nearest 15 minutes: up to 7 extra minutes round down, and 8 or more count as another unit (OAC 317:35-17-22). Round per visit, not per week. Convert minutes with the units calculator.

Reason codes

Oklahoma’s exact reason codes and their wording are set in AuthentiCare or HHAeXchange. These are the kinds of reasons it asks for:

Reason	When to use it
Missed clock-in or clock-out	The caregiver forgot to check in or out; the visit is entered manually
Device or app problem	Phone, app or battery failed during the visit
No signal at the home	Location could not be captured
Member refused or unavailable	The member would not use the phone or device
Service in the community	The visit took place away from the home
System outage	A confirmed outage of the state or vendor EVV system

Use the most specific reason. Payers audit free-text “Other” and repeated manual entries by the same caregiver.

Grace window

We did not find a set grace period for late clock-ins in Oklahoma’s EVV guidance. Small differences from the schedule usually pass; the EVV visit checker flags visits more than 15 minutes off schedule so you can add a reason first. Your health plan contract may set a tighter threshold.

Deadlines and the correction window

Since October 1, 2025, live-in caregivers are no longer exempt from EVV. OHCA has said the move to Acumen is not final and MCO providers stay on HHAeXchange. Correct the visit in your EVV system, confirm it is accepted, then resubmit the claim to OHCA or the SoonerSelect plan.

If a claim denies for EVV

Find the visit in your EVV system and read the rejection reason.
Fix the element (member ID, service code, times, location) and attach the reason code.
Confirm the aggregator shows the visit as accepted or verified.
Resubmit the claim. Do not resubmit before step 3; it denies again.

How Caregiver Scheduling handles Oklahoma EVV

Caregiver Scheduling captures the six elements with geofenced GPS check-in, logs an override reason when GPS can’t confirm the location, and flags late and missed check-ins for the office. In Oklahoma, visits count for SoonerCare only when they come from an OHCA-approved system or aggregator, so ask us how that works for your agency. GPS check-in and EVV.
