Electronic visit verification has been a compliance requirement for Medicaid-funded home and community-based services since the 21st Century Cures Act established the mandate. For most IDD agencies, the first few years of EVV felt like a documentation exercise: capture the data, meet the threshold, avoid a corrective action plan. The enforcement environment in 2026 is different. States have moved from monitoring compliance percentages to validating EVV data at the claim level. Incomplete or inaccurate EVV records no longer delay reimbursement: in a growing number of states, they deny it.
Understanding what state requirements actually demand, and what happens when those requirements are not met, is no longer optional for IDD agency leadership.
What a Compliant EVV Visit Record Requires
The data elements required for a compliant EVV visit record are defined at the federal level and enforced at the state level. Across all states with active EVV enforcement, a valid visit record must include:
- The type of service delivered
- The date the service was provided
- The location where service was delivered
- The individual receiving the service
- The individual providing the service
- The start and end time of the service
Any field that is missing, inconsistent with the submitted claim, or outside authorized parameters creates a hard edit rejection in states that have implemented claim-level validation. Common failure points include mismatched service codes between the EVV record and the claim, GPS data that does not align with the scheduled location, and caregiver credentials that are not properly linked to the visit record.
What States Are Doing in 2026
State enforcement is active and tightening. A few examples of what agencies are navigating right now:
- Missouri implemented major EVV hard edit validation in April 2026, affecting all waiver services. Hard edits validate service code accuracy, authorized hours, caregiver credentials, and time patterns at the point of submission. Agencies that did not use Missouri’s three-month testing window from January through March are experiencing the impact now.
- Michigan confirmed in late 2025 that EVV is now the central validation layer for billing accuracy and payment approval. For IDD agencies in Michigan, EVV data mismatches no longer result in delays: they result in denied payment.
- Minnesota began enforcement for all personal care assistant services in January 2026. Every visit now requires location data via GPS or address confirmation for home-based services.
- Illinois required agencies to reach 75 percent EVV visit compliance by September 30, 2025, and is maintaining quarterly compliance monitoring at that threshold. Agencies below 75 percent are subject to compliance monitoring, written response requirements, and potential referral to the Office of Inspector General.

Why IDD Agencies Face More EVV Complexity Than Other Provider Types
Home health agencies face EVV enforcement too, but IDD services present a more complex documentation environment. Consider what a single day might look like for a DSP: a morning shift at a group home with multiple clients, transportation to a community-based activity, support during a vocational session, and a return trip in the evening. Each service layer has its own documentation requirements. Overlapping shifts, group settings, community-based activities, and self-directed support models all create more opportunities for EVV data mismatches than a standard home health visit.
Meeting EVV requirements in this environment is not just about having an EVV app. It is about having an EVV system that captures the right data for each service type and connects that data to the billing record automatically.
The Structural Fix: Integration Between EVV and Billing
When EVV and billing are separate systems, your staff reconciles them manually before every billing cycle. That reconciliation step is where errors enter the process. A caregiver captures a visit in the EVV app. A billing coordinator exports that record and matches it to a billing entry. Any discrepancy between the two creates a potential denial, and under hard edit enforcement, it creates an actual one.
The only way to eliminate that risk structurally is to connect EVV and billing at the platform level. Vertex EVV Manager connects directly to Billing Manager and Case Manager, so visit data flows from capture to claim without a manual reconciliation step. The data needed to pass hard edits is captured automatically as part of normal service delivery.
EVV requirements will continue to evolve. States that are still in a monitoring phase will move to enforcement. Agencies that have already built compliant, integrated data workflows will be positioned to absorb those changes. Agencies running disconnected systems will face them as a crisis.
