How does EVV work in Massachusetts?

Massachusetts uses an open EVV model for agency-based services. An agency can use the state-sponsored EVV system from Sandata, which the Commonwealth pays for, or it can buy its own EVV software, which the state calls Alt-EVV. Either way, visit data ends up in the same place: Sandata is also the state's EVV data aggregator for the Executive Office of Health and Human Services (EOHHS).

A few points matter in practice:

• Registration comes first. Providers register for EVV through the state's Provider Self-Registration Portal, and an Alt-EVV system has to be registered there too.
• Alt-EVV data is sent daily. Agencies that use their own software send visit data to the Sandata aggregator every day.
• You can mix systems by program. The state's EVV questions and answers explain that a provider can use Sandata for one program and an Alt-EVV system for another, but separate EVV accounts are required.
• The state system has been available since September 30, 2024.

The consumer-directed Personal Care Attendant (PCA) program is a separate track. It uses its own EVV app and portal provided through the fiscal intermediary, Tempus Unlimited, not the agency Sandata system.

Which Massachusetts home care services require EVV?

EVV applies to agency-based home health, Group Adult Foster Care (GAFC), certain Acquired Brain Injury (ABI) and Moving Forward Plan (MFP) waiver services, and in-home services delivered under contract with an Aging Services Access Point (ASAP). The state publishes a service code table that lists the exact billing codes in scope for each program, and that table is the place to check your own services.

• Home health: the in-scope codes are G0151, G0152, G0153, G0156, G0299, G0300, G0493, T1022, T1502, T1503 and 99509.
• Group Adult Foster Care: the GAFC per diem visit, code H0043. Adult Foster Care (AFC) providers that are not group providers are not required to use EVV.
• ABI and MFP waivers: personal care, home health aide, supportive home care aide, skilled nursing by an RN or LPN, and physical, occupational and speech therapy in the home.
• ASAP-contracted services: personal care, home health aide, supportive home health aide, homemaking, companion, complex care training and oversight, and home safety and independence evaluations, for MassHealth or State Home Care members. Council on Aging programs that provide companion services only are not required to use EVV.
• Managed care: Managed Care Entity Bulletin 137 requires Accountable Care Partnership Plans, managed care organizations, One Care plans and Senior Care Options (SCO) plans to make sure their network providers use EVV, through the state system or a registered Alt-EVV system.

Does MassHealth deny claims without a verified EVV visit?

As of our last check, we could not confirm that MassHealth is denying claims for a missing EVV match. What is confirmed is that soft edits have been running since October 2025 for fee-for-service home health, GAFC and ABI and MFP waiver claims. Under soft edits, a claim with no matching verified visit is still paid, and the remittance advice carries an informational code. Claim denials (hard edits) have been announced for these same programs, but the state had not confirmed a start date in the latest materials we found.

Until claims edits begin, MassHealth measures compliance with checkpoints based on the share of visits that are auto-verified. For home health, GAFC and the ABI and MFP waivers, the checkpoint has been 50% since April 1, 2026, up from 40% before that.

For providers paid through a managed care plan or an ASAP, the picture is different. The state's May 2026 questions and answers say soft edits have not begun for providers contracted with managed care entities or ASAPs, and the state's hard edit materials do not cover them. The state has not published claim edit dates for either group, and it tells providers to work with their plan or ASAP on what is expected.

What is changing next for Massachusetts EVV?

The state's training materials describe how hard edits are expected to work once they start. A claim with no matching verified visit would be suspended for up to 30 days and re-checked each week, which gives the agency time to fix the visit record. A claim that still has no match at the end of that period would be denied. The state's hard edits cheat sheet lists the edit codes involved (2106, 2108, 2109, and 2127 for an unregistered provider ID and service location), all of which map to claim status code 784.

Two other items are announced without firm dates:

• Managed care claim edits. Bulletin 137 names a third phase in which managed care entities put claims edits into operation. No date has been published.
• Self-directed ABI and MFP waiver services. A December 2025 state bulletin said participants who self-direct would be required to use EVV to submit timesheets to the fiscal intermediary beginning in spring 2026. We could not confirm that this has started.

The practical step for now is the same either way: review your soft edit messages and clear unmatched visits each week, so that a change in enforcement does not change your cash flow.
