How do I check the Massachusetts Medicaid exclusion list?

The Massachusetts Medicaid exclusion list is published by the Massachusetts MassHealth (EOHHS), Office of Program Integrity. Screen each provider on your roster against it by NPI and name, confirm any match at the primary source, and document the check with its date. Fonteum mirrors the Massachusetts list alongside the OIG LEIE, SAM.gov, and 21 other state lists so you can clear it in one pass with a signed attestation.

Who publishes the Massachusetts Medicaid exclusion list?

Source: Massachusetts MassHealth (EOHHS). Fonteum mirrors that list as a source-traced screening aid and links back to the authority of record; the absence of a match means "nothing found in the list Fonteum currently holds," never a guarantee that none exists.

Is screening Massachusetts enough on its own?

No. A provider excluded by Massachusetts Medicaid may not appear on the federal OIG LEIE, and a provider your Massachusetts roster shows as clean may be excluded by another state. A defensible screen covers the OIG LEIE, SAM.gov, and every applicable state Medicaid list — the "excluded-anywhere" approach — not a single jurisdiction.

How often should I re-screen Massachusetts providers?

Monthly. The OIG recommends monthly screening against the LEIE, the penalty for employing an excluded provider accrues per item or service, and state lists update on their own schedules. Re-running the Massachusetts screen monthly and keeping a dated record is the defensible cadence.

Can Fonteum screen a Massachusetts roster for free?

Yes. Upload your roster and Fonteum runs a free same-day screen against the Massachusetts Medicaid list, the OIG LEIE, SAM.gov, and every other state list it mirrors, returning a signed, hash-chained attestation PDF in which each match traces to its source file and snapshot date. Public data only; no PHI, no demo.

What does a Massachusetts exclusion mean for payment?

An in-force exclusion means the program may not pay for items or services the excluded party furnishes, orders, or prescribes. Employing or contracting with an excluded individual can expose the organization to civil monetary penalties — up to $24,947 per item or service under Section 1128A of the Social Security Act — plus repayment. Confirm every match at the source before acting.

The process

How to screen a Massachusetts provider roster

Open the Massachusetts Medicaid exclusion listThe list is published by the Massachusetts MassHealth (EOHHS), Office of Program Integrity. The primary source is at Massachusetts Executive Office of Health and Human Services. Always treat that page as the authority of record.
Match every provider by NPI, then by nameCheck each provider on your Massachusetts roster against the list by NPI where the source publishes one, and by name where it does not. Confirm any hit against the primary list before any adverse action.
Screen the federal lists tooA Massachusetts match is necessary but not sufficient. Screen the same roster against the OIG LEIE and SAM.gov, because a federal exclusion may not appear on a state list and vice versa.
Screen every other state your providers touchA provider excluded in Massachusetts can relocate and bill elsewhere — and one excluded in another state can show up on your Massachusetts roster clean. For a multi-state roster, screen all 22 state Medicaid lists Fonteum mirrors, not just Massachusetts.
Document the screen and repeat monthlyKeep a dated record of which list you checked, the snapshot date, and any match. Re-run the Massachusetts screen on a monthly cadence, aligned to how often the source republishes.
