New York Medicaid Exclusion List
Published by the New York State Office of the Medicaid Inspector General (OMIG) (nightly). OMIG's list of individuals and entities excluded from New York Medicaid, refreshed on a nightly cycle. Healthcare organizations screen staff and contractors against it to protect their program participation and billing eligibility.
To look up one person, start from the official data file. This page summarizes the list itself: how many records it holds, how often it changes, and what to know when screening against it. It never lists individual people.
9,169
Actively excluded parties (records without a past reinstatement date).
9,169
Records on file, including any reinstated history the source publishes.
8,047 / 1,122
Individuals / businesses and other entities.
About this list
The OMIG list names both individuals and businesses excluded from New York Medicaid, mixed together in a single provider name column with no field marking which is which. Roughly 400 rows also carry an also-known-as or doing-business-as name written inline with the primary name. At the July 2026 verification the file held 8,975 rows. The list reflects current exclusions: there is no reinstatement column, and a party who is reinstated simply leaves the file.
Each row publishes five fields: provider name, license number, NPI, provider type, and the exclusion effective date. Names appear surname first with no comma. The file contains no date of birth and no address. An NPI is present on about 26 percent of rows and a license number on about 67 percent. Because the list has no DOBs, candidate matches from it rest on name comparison, supported by a license number or NPI where one is present, and need more verification from the reviewer than a source that publishes dates of birth.
OMIG publishes the list as a tab-delimited text file, the format this page links; spreadsheet and web versions of the same data also exist. Removals are visible only by comparison: a reinstated party's row is present in one day's file and absent from the next, and no field within the file records that the removal happened.

HHS-OIG's 2013 Special Advisory Bulletin on the Effect of Exclusion leaves screening frequency to each provider, and notes that because the LEIE is updated monthly, screening each month best limits overpayment and penalty liability.
