This guide explains Electronic Visit Verification (EVV) in general terms. Federal EVV requirements can be implemented differently by each state, so providers, caregivers, beneficiaries, and representatives should confirm current procedures with their state Medicaid agency and the state-approved EVV vendor. For federal background, consult the Medicaid.gov EVV guidance and the Centers for Medicare & Medicaid Services.
Electronic Visit Verification, commonly called EVV, is a system used to document certain Medicaid-funded services delivered during a visit to a person’s home or another approved location. EVV generally records information about who provided the service, who received it, when the visit occurred, where it occurred, and what service was delivered.
The purpose is to create a reliable electronic record of covered services. EVV can help states, managed care organizations, providers, and Medicaid programs compare scheduled services with services actually delivered. It can also support accurate billing, identify missing information, and reduce administrative disputes.
EVV is not one single national app or device. Each state decides how to operate its EVV program within federal requirements. A state may use a centralized system, an EVV vendor selected by the state, a provider-choice model, or an arrangement involving multiple systems. The exact process depends on the state, the Medicaid program, the service, and the provider’s enrollment status.
What does Electronic Visit Verification mean?
Electronic Visit Verification means electronically confirming information about a service visit. In practical terms, a caregiver or other authorized worker may use a mobile application, telephone system, web portal, or another approved method to record the beginning and end of a visit.
The system may then transmit the visit information to the provider, state, managed care organization, or another designated entity. Staff may review the record for errors before it is used for claims or other program functions.
EVV is focused on documenting a service encounter. It does not necessarily replace a provider’s broader scheduling, payroll, care-planning, clinical documentation, or electronic health record systems.
Why did the federal government require EVV?
Federal EVV requirements were created to improve oversight of certain Medicaid-funded personal care and home health services delivered in the home or other locations where the beneficiary receives care. The federal framework is associated with Section 12006 of the 21st Century Cures Act.
The federal goal is to help states verify that services billed to Medicaid were actually provided to an eligible individual by an authorized provider. EVV is one oversight tool. It does not by itself determine whether care was appropriate, whether a care plan was followed, or whether a person’s needs were fully met.
The federal government establishes requirements, but states administer Medicaid programs. As a result, implementation details such as enrollment, training, approved devices, correction procedures, interfaces, and claim rules may differ.
Which services are subject to EVV?
Federal EVV requirements generally apply to Medicaid-funded personal care services and home health services when those services require an in-home visit. The requirement can apply whether the service is delivered under a state plan or a Medicaid waiver, depending on the circumstances and the state’s program design.
Not every service that occurs in a person’s home is automatically subject to EVV. Coverage depends on the service definition, the funding authority, the provider arrangement, and state policy. Some services may be excluded, delayed, or treated differently under state rules.
Providers should not rely only on a service name. A service that appears similar to a covered personal care or home health service may have different EVV treatment. Confirm the answer with the state Medicaid agency, managed care organization, or other official program contact.
What information must an EVV record include?
Federal guidance identifies six core categories of information for an EVV record:
- The type of service performed.
- The individual who received the service.
- The date of service.
- The location where the service was provided.
- The individual who provided the service.
- The time the service began and ended.
A state system may collect additional information. For example, it may request an authorization number, service code, visit status, reason for an exception, worker identification, supervisor review, or information needed to connect EVV data with a claim.
Because system fields vary, providers should use the state’s current training materials and instructions rather than assuming that a record is complete simply because a visit was clocked in and clocked out.
How does an EVV visit usually work?
A typical process begins with an authorized schedule or service authorization. The worker then starts the visit using an approved method. Depending on the state system, the worker may use a mobile application, a telephone call, a fixed device, or a web-based process.
At the end of the visit, the worker records the departure or completes the required end-of-visit action. The system may capture time and location through the approved technology. The provider then reviews the information and corrects documented errors through the permitted process.
Some systems allow a worker to enter information after a visit when a technical problem occurred. That does not mean a worker may freely reconstruct visits without explanation. Late entries, missing clock events, location mismatches, and other exceptions may require a reason and supervisor approval.
The workflow may be different for live-in caregivers, self-directed services, shared services, overnight care, telehealth-related activities, or visits that begin and end at different locations. State guidance controls these situations.
Does EVV use GPS or track workers all day?
Some EVV applications use location information to confirm where a visit starts or ends. The precise location features depend on the state-approved system and the device settings. EVV is generally intended to verify a service visit, not to create continuous personal surveillance.
However, privacy practices can differ. A mobile application may request location permission, and the provider or state may establish rules for when location data is collected. Workers should review the system’s instructions and ask the provider or state program contact how location information is used, stored, and corrected.
Providers should explain the process clearly to workers and beneficiaries. A person receiving care should understand what information is collected and whom to contact if the recorded location or visit details are wrong.
What happens if a worker forgets to clock in or clock out?
A missed clock-in or clock-out is usually treated as an exception. The worker should report the problem promptly and follow the provider’s correction procedure. A supervisor or authorized reviewer may need to verify the visit and record a reason for the correction.
Providers should never invent time, location, or service information to make a record appear complete. The correction should reflect what actually happened and should be supported by available documentation. Repeated exceptions may indicate a training, device, connectivity, scheduling, or system problem that needs attention.
State rules determine whether a claim can be submitted while an EVV record is incomplete. A provider should not assume that a manual note, spreadsheet, or timesheet can replace an EVV record unless the state or other authorized program entity permits that method.
What if there is no cell service or internet connection?
Many EVV systems are designed to address limited connectivity, but the available options vary. An application may store information temporarily, a telephone system may provide another method, or the provider may have an approved exception process.
Workers should learn the backup process before a problem occurs. They should also document the issue according to provider instructions and avoid submitting duplicate visits when the system later synchronizes data.
If technical problems occur repeatedly, the provider should contact the EVV vendor or state support channel. The state may distinguish between a legitimate technology exception and a visit that was never documented. That distinction can affect billing and compliance review.
Who chooses the EVV vendor?
The state determines how its EVV program is organized. In some states, the Medicaid agency selects a primary vendor. In other states, providers may choose from approved vendors that send information to a state aggregator or another required platform. A managed care organization may also provide instructions that affect the provider’s workflow.
Do not assume that a commercial timekeeping application is an approved EVV system. A product may record hours for payroll but still fail to transmit the data required by the state. Before purchasing software, signing a contract, or changing systems, ask whether the vendor is approved for the specific state program and service.
Confirm locally:
- Which EVV vendor or vendors are approved.
- Whether the vendor must connect to a state aggregator.
- Which services and provider types must use EVV.
- Whether the system supports the provider’s billing and care model.
- How training, technical support, corrections, and system outages are handled.
How should a provider confirm the correct state vendor?
Start with the state Medicaid agency or the official program instructions connected to the provider’s enrollment. If the provider participates in managed care, also check instructions from each applicable managed care organization. A provider should identify the exact program, service code, waiver or state plan authority, and billing arrangement before asking for a vendor recommendation.
Ask for confirmation in writing when possible. The provider should know whether enrollment with the vendor is separate from Medicaid enrollment, whether the vendor has an implementation deadline, and whether the state requires testing before claims are submitted.
Workers and beneficiaries can ask the provider which system is being used and how to report a problem. If the answer is unclear, contact the appropriate state Medicaid support channel. The general federal EVV information on Medicaid.gov can provide background, but it does not replace state-specific instructions.
How does EVV affect Medicaid billing?
States may use EVV information to support claims processing, compare billed units with recorded visits, or identify claims that need review. The relationship between EVV and billing differs by state. Some systems send information directly to a claims process, while others require a provider to submit a separate claim after reviewing the visit.
EVV does not automatically prove that a claim is payable. Eligibility, authorization, covered service definitions, provider enrollment, units, documentation, and other Medicaid requirements still matter.
Providers should reconcile EVV records with schedules, authorizations, payroll, service notes, and claims. Differences should be investigated before submission. A typical software subscription or implementation cost can vary widely by vendor and provider size, so providers should request written pricing and confirm whether any costs are allowed or reimbursable under their state arrangement. There is no single federal EVV price that applies to every provider.
What are the benefits of EVV for beneficiaries?
A well-designed EVV process can give beneficiaries a clearer record of when authorized care was scheduled and delivered. It may make it easier to identify missed visits, incorrect times, duplicate billing, or services recorded under the wrong worker.
EVV can also support accountability when a beneficiary or representative questions a claim. The record may help establish what was submitted, although it may not answer every question about the quality or usefulness of the care.
Beneficiaries should review notices, service records, and care documentation when available. If a visit is recorded inaccurately, the beneficiary or representative should notify the provider promptly and ask how to request a correction. Concerns about fraud, abuse, neglect, or unsafe care may require a separate report through the appropriate state or program channel.
What are the challenges and risks of EVV?
EVV can create operational challenges. Workers may have difficulty using a new application, beneficiaries may have privacy concerns, and providers may need to reconcile multiple systems. Rural areas, shared phones, limited broadband, language barriers, disabilities, and changing service locations can also affect implementation.
Data errors are another risk. A wrong service code, incorrect worker profile, duplicate record, missed event, or inaccurate location can create a mismatch. A system record should be reviewed as business information, not treated as infallible proof.
Providers should limit access to EVV information, train staff on privacy and security, establish a correction process, and retain records as required by applicable program rules. Questions about privacy, records, and complaints should be directed to the provider, EVV vendor, managed care organization, or state Medicaid agency, depending on the issue.
What should providers do before starting EVV?
Providers can prepare by identifying every service and payer affected by EVV. They should confirm whether each service requires EVV, verify authorizations, review worker information, and ensure that beneficiary records are accurate.
A practical readiness checklist includes:
- Confirm the state’s current EVV requirements.
- Confirm the approved vendor or vendor options.
- Complete required enrollment and training.
- Test devices, telephone access, applications, and internet connections.
- Train workers on starting visits, ending visits, and reporting exceptions.
- Explain the process to beneficiaries and representatives.
- Create a written correction and outage procedure.
- Reconcile EVV data with schedules, documentation, payroll, and claims.
- Keep records of support requests, corrections, and approvals.
Providers should assign responsibility for daily review. A system can capture data, but people still need to check whether the data is accurate, timely, and consistent with the care that was authorized and delivered.
Where can you get authoritative EVV information?
Start with the state Medicaid agency because the state controls most implementation details. Providers should also review communications from managed care organizations, waiver administrators, and the approved EVV vendor. Ask for current materials because requirements and system procedures can change.
For federal background, use the official Medicaid.gov EVV resource. The CMS website provides broader information about federal Medicaid administration and related program guidance.
The most important rule is simple: confirm locally before acting. The state’s approved vendor, required data fields, correction process, claim workflow, privacy instructions, and exception rules may not match those in another state. Correct EVV compliance begins with using the right system for the right service under the right state instructions.
