OIG Exclusion Screening: Whose Job Is It for Referrals?

Key Finding OIG exclusion screening is not just for your own staff. If you bill for a service ordered by an excluded provider, you can be liable. The billing practice carries the risk, not the outside referrer. That makes screening referring providers your job, not someone else's. This guide shows how to do it safely.

 

An outside physician refers a patient, and you bill the service. Nobody at your practice checked whether that referrer is excluded. Under OIG exclusion screening rules, that gap is your exposure, not theirs. The liability follows the claim you submitted, not the referral they sent. This feels like someone else's problem, and it is not. A credentialing and compliance gap can turn into a real penalty. The referral was routine. That claim you billed carries the risk.

 

A note on scope. Exclusion screening decisions and final determinations rest with your practice or health center. A credentialing partner like HRG supports the surrounding workflow. That work covers coordinating the screening, documenting the checks, and maintaining the files. Your organization conducts the screening and retains authority over the decisions.

What OIG exclusion actually blocks

OIG exclusion is a hard line, not a warning. An excluded provider cannot participate in federal health programs. No federal dollar may pay for what they furnish. The block extends to what they order, prescribe, or refer. Bill for a service tied to an excluded provider, and Medicare will not pay. Worse, you can face civil monetary penalties. The OIG maintains the excluded parties on its List of Excluded Individuals and Entities. That list updates every month.

The referring-provider gray zone

Most practices screen their own staff and contractors. Fewer think about outside referring providers. That is where the confusion lives. The referrer does not work for you, so it feels like their problem. Your claim, though, is a different story. OIG guidance ties the payment prohibition to ordered and referred services. If you bill it, the exposure attaches to you. The OIG Special Advisory Bulletin lays out this effect of exclusion. That gray zone is real, but the risk is not evenly shared. OIG exclusion screening has to reach beyond your own staff.

Who actually carries the risk

Here is the plain answer to the question. The billing entity carries the exclusion risk. You submitted the claim, so you own the exposure. The standard is whether you knew or should have known. Should have known is the phrase that bites. A monthly OIG exclusion screening is how you show you checked. Skip it, and you cannot claim you did not know. Screening referring providers is not optional diligence. It is how you protect the claim you already billed.

Monthly: how often the OIG updates the LEIE, and how often you should screen.

How to screen the right way

Good OIG exclusion screening is a routine, not a scramble. Screen every month, because the LEIE changes every month. Check the OIG list and the SAM.gov exclusions together. Add your state Medicaid exclusion list where it applies. Screen employees, contractors, and the providers who order or refer. Document every check with a date and a result. Keep the records, because an audit will ask for them. Routine, documented screening is what turns exposure into a defense.

How HRG handles OIG exclusion screening

Here is HRG's lane in OIG exclusion screening. HRG coordinates the screening workflow against the OIG and SAM lists. Your practice conducts the screening and owns the decisions. HRG documents each check and keeps the files audit-ready. The team screens employees, contractors, and ordering or referring providers. It runs the checks monthly, in step with the LEIE update. HRG works inside your existing systems, not a separate dashboard. No PDF reports, no offshore handoffs, no guesswork. When a match appears, HRG flags it in 24 to 48 hours. Over 26 years, HRG has kept clients' credentialing files audit-ready. U.S.-based staff run the screening, not an offshore queue. So an excluded referrer surfaces before the claim goes out.

If you are not screening your referring providers, you have a blind spot. Closing it is exactly what HRG helps you do. Talk through your exclusion process with Mellissa Harmon before an audit does. Book a credentialing review with Mellissa. No pitch, no contract pressure.

OIG exclusion screening questions practices ask

Do we have to screen outside referring providers?

You should, for any claim you bill on their order or referral. The payment prohibition extends to ordered and referred services. If the referrer is excluded, your claim is at risk. HRG coordinates screening of your referring providers so the gap closes.

How often should we run OIG exclusion screening?

Every month, because the OIG updates the LEIE monthly. A quarterly check leaves weeks of exposure between screens. Monthly screening is the OIG's own recommendation. HRG runs the checks monthly and documents each one.

Who is liable if an excluded provider refers a patient?

The billing entity carries the exposure, not the outside referrer. You submitted the claim, so the risk attaches to you. The standard is whether you knew or should have known. HRG helps you show you checked, which is your defense.

What lists do we need to check?

Start with the OIG LEIE and the SAM.gov exclusions. Add your state Medicaid exclusion list where it applies. Checking one list alone leaves gaps the others catch. HRG coordinates screening across all of them.

Does HRG make the exclusion determination for us?

No. Your practice conducts the screening and owns the final decision. HRG coordinates the workflow and documents each check. That keeps HRG a compliance partner, not the decision-maker.

What happens if we bill for an excluded provider's service?

Medicare will not pay, and you may owe civil monetary penalties. Payers can claw back the money already collected as an overpayment. Routine screening is what prevents that outcome. HRG keeps the screening current so the claim stays clean.

The answer, and the habit it demands

The question has a clear answer after all. If you bill the claim, the exclusion risk is yours. Screening referring providers is your protection, not a favor to them. Make OIG exclusion screening a monthly routine, and exposure turns into a defense. See how HRG approaches provider credentialing.
