How to check Washington Medicaid exclusions
Screen every provider on your Washington roster against the Washington Medicaid exclusion list — published by the Washington State Health Care Authority (HCA)— plus the federal OIG LEIE and SAM.gov, and document each check with its date. Here is the process and the source. Fonteum's free product screen covers OIG LEIE, SAM.gov, and 13 state Medicaid jurisdictions represented as of August 4, 2026, including Washington. It accepts the first 25 unique ten-digit NPI inputs and shows counts plus a matched-source breakdown on screen.

How to screen a Washington provider roster
- Open the Washington Medicaid exclusion listThe list is published by the Washington State Health Care Authority (HCA). The primary source is at Washington State Health Care Authority. Always treat that page as the authority of record.
- Match by NPI when present, then use source-supported name fieldsCheck each provider on your Washington 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 Washington 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 applicable stateA provider excluded in Washington can relocate and bill elsewhere — and one excluded in another state may not appear on a Washington-only screen. For a multi-state roster, screen every applicable state at its primary source. Fonteum's product currently checks 13 state Medicaid jurisdictions represented as of August 4, 2026, not all states.
- Document the screen and set a recurring cadenceKeep a dated record of which list you checked, the date of the copy you checked, and any match. Follow the Washington program's current rules and source cadence; OIG separately says monthly LEIE screening best minimizes potential liability.
Washington exclusion screening — common questions
- How do I check the Washington Medicaid exclusion list?
- The Washington Medicaid exclusion list is published by the Washington State Health Care Authority (HCA). 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. Washington is one of the state lists currently loaded by Fonteum, alongside OIG LEIE and SAM.gov. Stale or incomplete coverage returns indeterminate, not a clearance.
- Who publishes the Washington Medicaid exclusion list?
- Source: Washington State Health Care Authority (HCA). This guide links back to the authority of record; Fonteum currently loads this list as a screening aid; an absence is a no-match only under reconciled current coverage. Stale or incomplete loaded coverage is indeterminate and not a clearance.
- Is screening Washington enough on its own?
- No. A provider excluded by Washington Medicaid may not appear on the federal OIG LEIE, and a provider with no Washington-list match 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 Washington providers?
- Follow the WashingtonMedicaid program's current rules and the source's own update cadence. OIG separately advises checking the LEIE before employing or contracting and periodically afterward, and says monthly LEIE screening best minimizes potential liability. Keep a dated record of every applicable check.
- Can Fonteum screen a Washington roster for free?
- Yes, for the first 25unique ten-digit NPI inputs. Fonteum's on-demand screen checks the Washington Medicaid list, OIG LEIE, SAM.gov, and the other currently loaded state lists. 13 state Medicaid jurisdictions represented as of August 4, 2026. It shows counts and a matched-source breakdown on screen only, with no free artifact, email, or monitoring. Stale or incomplete coverage is indeterminate. Public data only; no PHI — start at the on-demand screen.
- What does a Washington 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. Civil monetary penalties, assessments, and repayment can apply when federal programs are billed for items or services furnished by an excluded party. Applicable amounts change over time; confirm current rules and every match at the primary source (see OIG guidance).
