Electronic Visit Verification (EVV) in South Carolina
All states: EVV requirements map
In short: The state requires its own EVV system (AuthentiCare) for waiver in-home care, and claims are generated from its visit data. Change ahead: South Carolina has chosen a replacement EVV vendor, and a more open model has been described. No go-live date has been published.
South Carolina EVV at a glance

| Aggregator | None today. Visits are captured in the state system and Phoenix submits the claims. |

| Are claims tied to EVV? | Yes for the four SCDHHS-run waivers. Claims are generated from EVV visit data, for authorized services and units only. |
| Programs without EVV today | The ID/RD, Community Supports and HASCI waivers do not require the EVV billing system. |

How does EVV work in South Carolina?
South Carolina runs its own EVV system. The South Carolina Department of Health and Human Services (SCDHHS) requires providers of in-home services in four of its waivers to take part in all components of the state EVV system, which is AuthentiCare from Fiserv. Caregivers check in and out by landline phone (IVR) or by smartphone app. We did not find any state document that describes another way to capture these visits today.
The four waivers are:
- Community Choices
- HIV/AIDS
- Mechanical Ventilator Dependent
- Medically Complex Children
AuthentiCare works together with Phoenix, the SCDHHS case management system. Phoenix holds the service authorizations and schedules, and the EVV system uses them to check that the service delivered matches what was authorized. Participant-directed services in these waivers are also documented under the EVV guidelines, with payment going through the fiscal agent.
One recent change matters for every caregiver's phone. A notice on the Phoenix provider portal dated September 28, 2026 said AuthentiCare 2.0 would be retired on September 30, 2026, and that workers must use AuthentiCare 3.0. If any of your caregivers are still on the older app, move them now.
Are South Carolina Medicaid claims tied to EVV visits?
Yes, for the four SCDHHS-run waivers. The approved waivers say in-home services require EVV and that claims are generated from EVV visit data. Agencies do not build these claims themselves. Phoenix submits them to the state's Medicaid claims system, and only for services and units that were authorized.
A few points follow from that design:
- The authorization sets the ceiling. A claim is submitted only up to the authorized level, so time worked beyond the authorization does not turn into extra billed units.
- Direct billing is the exception. The Community Choices waiver says providers may bill directly in Phoenix only when there was a worker error or the system was unavailable.
- Fix problem visits quickly. The provider manual says resolutions must be uploaded in Phoenix within two weeks of the date of service.
- Billing runs most days. The manual says the EVV system generates billing six days a week.
In practice, a visit that was delivered but not recorded correctly in the state system is a visit that does not produce a claim until someone fixes it. Agencies that review exceptions every day stay ahead of that two week window. We did not find a published date for when this link between visits and claims began.
Which South Carolina programs do not use EVV today?
Three waivers do not require the EVV billing system today: Intellectual Disability and Related Disabilities (ID/RD), Community Supports (CS) and Head and Spinal Cord Injury (HASCI). These waivers are operated by the Office of Intellectual and Developmental Disabilities, formerly SCDDSN. Providers in these programs can submit claims through the South Carolina Medicaid Web-based Claim Submission Tool, and the manual asks for claims at least within the quarter after the date of service.
SCDHHS planned to launch EVV for these waivers on December 11, 2022, then postponed the launch. We did not find a later launch notice or a new date.
Home health is less clear. The federal Centers for Medicare and Medicaid Services approved a good faith effort exemption for South Carolina's home health care services for calendar year 2023. We did not find an SCDHHS notice showing that EVV is live for Medicaid home health visits. If you bill Medicaid home health, check the current rule with SCDHHS before you assume either answer.
What is changing next for South Carolina EVV?
South Carolina has awarded its EVV contract to HHAeXchange, but AuthentiCare is still the system providers use, and no go-live date has been published. A state vendor conference deck from April 2026 listed AuthentiCare as the current EVV system and the future EVV vendor as still to be determined. The same deck said the new EVV is meant to expand coverage to all required services.
Important: HHAeXchange's own South Carolina page says providers will be able to use a free HHAeXchange portal or a third-party EVV vendor that integrates with it, under a new open model. That page carries no dates, and we did not find an SCDHHS document that confirms the open model. Treat it as announced, not final, and keep using the state system until SCDHHS tells you otherwise.
Several things are not yet known: when the new system starts, which programs move first, whether the ID/RD, CS and HASCI waivers will be brought under EVV, and whether home health will be included. SCDHHS has said in its waiver documents that changes to EVV requirements will be announced by Medicaid bulletin at least 30 days ahead, so the bulletins are the place to watch.
The state has also started a new procurement for the fiscal agent that handles participant-directed services, because the current contract is expiring. No vendor or date has been announced for that either.
