OIG Exclusion Screening: The Monthly Check Most Independent Practices Skip
Employing one excluded individual exposes a practice to civil monetary penalties assessed per item or service that person furnished, plus repayment of amounts the federal health care programs paid for those services -- so a single medical assistant working 6 months before anyone checks can generate a five-figure liability from a screen that takes 10 minutes. The screening obligation is continuous, not a hiring-day formality, and it reaches contractors and vendors, not just employees on payroll.

The Short Answer
Screen every employee, contractor, and vendor against the OIG List of Excluded Individuals and Entities before hire and monthly thereafter, screen against your state Medicaid exclusion list in every state where you bill, and keep dated evidence of each screen. The evidence is the part practices skip, and it is the part that matters when someone asks you to prove the screening happened.
What Exclusion Actually Prohibits
An excluded individual or entity is barred from participating in federal health care programs. The practical prohibition is broader than most practices assume: no federal health care program payment may be made for any item or service furnished by an excluded person, or furnished at the direction or on the prescription of an excluded person. That sweeps in staff who never touch a claim.
The billing clerk who posts payments, the medical assistant who rooms patients, the contracted transcriptionist, and the cleaning service that holds a facilities contract all fall inside the screening obligation, because the prohibition attaches to the payment for services the practice furnishes, not to whether the individual personally submitted a claim. The OIG Special Advisory Bulletin on the Effect of Exclusion from Federal Health Care Programs, 2013, is the authority practices should read on scope, and it is where the monthly screening cadence recommendation comes from.
Exclusion is also not the same as a licensure action, and the two lists do not mirror each other. A clinician can hold an active, unrestricted state license and still be excluded, most commonly following a program-related conviction in another state. A license verification is not an exclusion screen, and a practice that treats primary source license verification as covering this obligation has a gap it does not know about.
| List | Source | Recommended cadence | Who must be screened | Who owns it |
|---|---|---|---|---|
| LEIE (federal exclusions) | HHS Office of Inspector General | Pre-hire and monthly | Employees, contractors, vendors, volunteers, board members | Practice administrator or compliance lead |
| State Medicaid exclusion list | Each state Medicaid agency | Pre-hire and monthly, per billing state | Same population, in every state where the practice bills Medicaid | Practice administrator |
| SAM.gov exclusions | General Services Administration | Pre-hire and periodically | Vendors and contracting entities | Whoever owns vendor contracting |
| Preclusion List | Centers for Medicare and Medicaid Services | Per payer instruction | Prescribers and providers billing Medicare Advantage or Part D | Credentialing service or credentialing staff |
| State license verification | State licensing boards | At credentialing and renewal | Licensed clinicians only | Credentialing service |
Why Monthly, and Why the Evidence Matters More Than the Search
The LEIE is updated monthly. A pre-hire screen tells you about the moment of hire and nothing after it, and exclusions are frequently imposed on people already employed somewhere. Monthly screening is the cadence that matches the update frequency of the underlying data, which is why it is the recommended interval rather than an arbitrarily conservative one.
The failure mode in practice is almost never that nobody searched. It is that nobody can prove it. A screen run in a browser and closed without a saved result is operationally identical to no screen at all when the question arrives later. Retain, for each screening cycle, the date, the list searched, the exact name and identifier strings used, the result, and who ran it. For any name that returns a potential match, retain the resolution: the identifier that distinguished your employee from the excluded individual, and who verified it.
Name matching is the other quiet problem. The LEIE returns matches on common names that are not your employee, and resolving those requires a secondary identifier such as date of birth or Social Security number, verified through the OIG's own verification step rather than assumed. A practice that resolves potential matches by informal judgment and keeps no record has documented nothing.
How to Actually Run the Program
- Define the screening population in writing: list every category -- W-2 staff, 1099 contractors, locums, vendors with facility access, billing company personnel, board members. The most common gap is contractors and vendors, because they are not on the payroll report the screen is usually built from.
- Decide build versus buy on volume: manual LEIE and state-list screening is workable for a small practice at roughly 15-45 minutes per month. Above about 25 covered individuals, or in more than one billing state, a screening vendor is usually cheaper than the staff time and produces better evidence.
- Push the obligation into vendor contracts: require in writing that any vendor whose personnel touch your operations screens its own staff monthly and will attest to it annually. This does not transfer your liability, but it makes the vendor's failure a contract breach you can act on.
- Set a fixed monthly date and an owner by name: unowned recurring compliance tasks lapse first. Put it on a named person's calendar with a defined artifact to file.
- Write the hit protocol before you need it: if a screen returns a verified exclusion, the person comes off all federal program work immediately, the practice quantifies what was billed for items and services they furnished, and counsel is engaged on self-disclosure. Deciding this under pressure produces worse outcomes than deciding it in advance.
Practices that already run monthly credentialing maintenance can attach this to the same cycle rather than building a separate process. It fits alongside the recurring obligations covered in the supervision and billing rules for unenrolled providers.
What Goes Wrong
- Screening only at hire: the single most common gap. It leaves the practice blind to any exclusion imposed after the start date, which is the majority of exposure.
- Screening employees but not contractors or vendors: the screening list is built from payroll, so everyone paid through accounts payable is invisible to it.
- Federal list only, in a Medicaid-billing practice: state Medicaid exclusion lists are separate, and a person can appear on a state list without appearing on the LEIE.
- No retained evidence: the search happened and cannot be demonstrated, which for compliance purposes is the same as not having happened.
- Potential matches resolved informally: a common-name hit is dismissed without recording the identifier that ruled it out or who made the call.
- Assuming the billing company screens its own people: most contracts are silent on it. Silence is not an assurance, and the practice is the party billing the federal program.
What Should You Do?
Write down the screening population including contractors and vendors, assign a named owner and a fixed monthly date, screen the LEIE and every applicable state Medicaid list, and file dated evidence of each cycle including how potential matches were resolved. Add a screening-and-attestation clause to vendor contracts at the next renewal. If the practice covers more than about 25 individuals or bills Medicaid in more than one state, price a screening vendor against the staff hours the manual process consumes -- the vendor usually wins on cost and always wins on evidence quality.

Frequently Asked Questions
- How often does the OIG recommend screening the exclusion list?
- Monthly. The OIG Special Advisory Bulletin on the Effect of Exclusion from Federal Health Care Programs, 2013, ties the recommended cadence to the LEIE's monthly update cycle, so a monthly screen matches the frequency at which the underlying data changes.
- Must contractors and vendors be screened, or only employees?
- Both. The prohibition attaches to federal health care program payment for items and services furnished by an excluded person, regardless of how that person is paid. Contractors, locums, billing company personnel, and vendors with operational access all fall inside the screening population.
- Is checking a state license the same as an exclusion screen?
- No. The lists are maintained separately and do not mirror each other. A clinician can hold an active unrestricted license and still be excluded, most often after a program-related conviction in another state.
- What happens if a current employee turns up on the exclusion list?
- Remove them from all federal health care program work immediately, quantify what was billed for items and services they furnished during the exclusion period, and engage counsel on whether self-disclosure is appropriate. Deciding this sequence in advance produces better outcomes than improvising it.
- Does screening the federal list cover a practice's Medicaid obligations?
- Not by itself. State Medicaid agencies maintain their own exclusion lists, and a person can appear on a state list without appearing on the federal LEIE. Screen every state in which the practice bills Medicaid.
