Why GPS-Based EVV Fails in Rural Areas — And What to Do About It

The Connectivity Problem Nobody Talks About

The 21st Century Cures Act mandated Electronic Visit Verification for all Medicaid personal care and home health services. States that didn't comply faced reductions in their Federal Medical Assistance Percentage. The mandate was clear. The deadline was firm.

What the mandate didn't account for was the rural connectivity gap.

According to the FCC, approximately 21 million Americans lack access to fixed broadband. Cellular coverage in rural areas is significantly worse. Home health agencies serving patients in West Texas, rural Appalachia, the Mississippi Delta, and tribal lands in the Southwest routinely operate in areas where their caregivers have no data connection.

GPS-based EVV — the dominant implementation — requires a smartphone with a data connection to submit a visit record. In a dead zone, the app fails. The visit record is not submitted. The agency has a compliance gap.

The Workarounds Are Worse Than the Problem

Agencies in rural areas have developed workarounds for this connectivity gap, and most of them create more problems than they solve.

Delayed submission — caregivers drive to a location with cell service and submit multiple visit records at once. This creates a suspicious pattern in audit data: multiple visits submitted from the same location at the same time. RAC auditors flag this.

Pre-submission — caregivers submit the visit record before arriving at the patient's home, using the patient's address as the GPS coordinate. This is technically EVV fraud, even if the visit actually happened.

Paper backup — agencies revert to paper visit logs for rural patients and submit them manually. This defeats the entire purpose of EVV and creates a two-tier compliance system that is difficult to defend in an audit.

The Offline-First Alternative

VerifiedKnock was designed from the ground up for environments where connectivity cannot be assumed.

The verification process requires zero internet connection at the point of care:

1. The caregiver activates their ATKey.Card with their fingerprint — on-card biometric match, no data connection required.
2. The activated card taps the NFC sticker at the patient's door — creates a cryptographically signed visit record, stored on-card.
3. When the caregiver returns to a connected area, visit records sync automatically.

The visit record is created at the moment of care, not when connectivity is available. The timestamp is cryptographic and cannot be retroactively altered. There is no "delayed submission" pattern because the record is created on-hardware at the time of the visit.

What This Means for State Medicaid Programs

States with large rural populations — Texas, California, Montana, Wyoming, the Dakotas — have a structural EVV compliance problem that GPS-based systems cannot solve. Agencies serving rural patients are either out of compliance or using workarounds that create audit risk.

VerifiedKnock provides a path to genuine compliance for rural home health agencies. No connectivity required. No workarounds. No audit risk.

We are currently working with state Medicaid programs to evaluate VerifiedKnock as a rural EVV solution. If you represent a state Medicaid program or a home health agency serving rural patients, we want to talk to you.
