Nevada EVV requirements: Sandata and Addendum B

Nevada’s EVV timeline in brief

When Nevada’s EVV rules and systems changed, with the paper behind each date:

Phone readers can swipe the table left to see what changed and which paper says so. Every date above was set beside its paper on November 9, 2026.

What Nevada Medicaid writes

On the vendor question, the Nevada Medicaid EVV page, last updated October 22, 2026, describes a “hybrid model where the state contracts with at least one EVV vendor” while letting providers with existing systems keep them. On location, MSM Addendum B, effective January 1, 2024, is just as direct: “The EVV system does not ‘track’ the recipient or their caregivers.”

What every Nevada visit record holds

Addendum B, effective January 1, 2024, names six things per visit: what kind of service, who got it, on what day, at what location, which worker gave it, and the times it began and ended. Agencies using an alternate system add procedure codes and tasks, the recipient’s Medicaid ID, the agency’s and caregiver’s National Provider Identifiers, and how the visit was captured, with the phone number, location reading or encryption key that goes with that method.

Manual entries and paper timesheets

The addendum keeps EVV use at 90 percent or higher and counts unexplained manual entries, partial records and shift edits against the other 10 percent. Each manual entry or edit carries its reason and an audit trail, kept for seven years. Paper timesheets come in only where the caregiver and recipient live in an area with no landline, cell or internet service, or where there is a documented safety concern, and the time is then checked separately.

Denials, recoupment and the 2026 changes

In the words of Addendum B to the Nevada Medicaid services manual, effective January 1, 2024, a claim for a service on EVV “may be rejected or denied, or subject to recoupment, if delivery of the service was not verified by EVV.” Two 2026 announcements change how that plays out. From April 1, 2026, per announcement 3877 of March 30, 2026, EVV claims go straight to each payer instead of through Optum. Announcement 3891, a Nevada Medicaid provider notice of April 10, 2026, turned five unmatched-visit and duplicate-visit error codes from denials into informational messages.

Family caregivers and live-in workers

None of the Nevada materials reviewed here carves out live-in caregivers. Chapter 2300 of the Nevada Medicaid services manual, effective April 1, 2025, says legally responsible individuals paid under the Physically Disabled waiver “must utilize” EVV “for check in/check out.” The only live-in line in that chapter limits hours, not EVV.

Gaps in the Nevada record

No source read from Nevada Medicaid gives the day personal care first went on EVV, and no state FAQ or training deck turned up; training is left to Sandata. Announcement 3186 of October 11, 2023 gave an expected Sandata start for providers in mid-December 2023, which this page treats as a target, not a date. The statutes, chapters 2200 and 2400, and Sandata’s own help pages went unread.

Where LockProof sits beside Nevada EVV

Under Addendum B, effective January 1, 2024, Nevada Medicaid weighs EVV records against the claims they back. A family paying privately, or a relative watching a parent’s care, can keep its own photo record of visits with LockProof. Compare photo apps a Nevada agency can keep running with EVV, or walk through a single LockProof caregiver visit.
