How Often Should You Screen for OIG Exclusions?

Monthly. That is the answer, and it is not arbitrary — it is the cadence OIG publishes on, the cadence CMS directed state Medicaid programmes to require, and the cadence most payer contracts name. Everything below is why, and what the alternatives actually cost.

Where monthly comes from

The convergence is not a coincidence. OIG republishes the complete file monthly, so a monthly check is the shortest interval at which anything can actually have changed in the source. Checking weekly against a file that is republished monthly does not find anything a monthly check would have missed — it just finds the same thing three weeks earlier if you happen to run it after a republication.

What a longer gap costs

The cost of a gap is not theoretical, and it is not a fine for the gap itself. The exposure is that every item or service an excluded person touches during the gap is unpayable — and the remedy is repayment of what was already paid, potentially with penalties on top. A quarterly screening cycle means that in the worst case an exclusion sits undetected for nearly three months of billing.

• The payment prohibition starts on the exclusion date, not on the date you discover it.
• Amounts already paid for services furnished during that period are subject to recovery.
• Civil monetary penalties attach where the organization knew or should have known — and an organization screening annually has a harder time arguing it could not have known.
• Self-disclosure is available and is the right course when something is found, but the amount at stake scales with how long the gap was.

When more often makes sense

A monthly baseline covers most organizations. Three situations justify checking more often.

• At hire and at contracting, always. Screening a new person on their start date rather than waiting for the next monthly cycle is the single highest-value check there is — it is the moment before any billing has happened.
• When a contract says so. Some payer and state Medicaid agreements specify a shorter interval, or require screening against state lists on their own cadence. The contract governs.
• For SAM.gov, which is not monthly. SAM is updated continuously rather than republished on a cycle, so a more frequent check against it genuinely finds things sooner. That is why NPISignal queries SAM live rather than holding a copy.

What monthly does not mean

It does not mean screening the same list of names every month and filing an identical result. A monthly cycle only produces value if three things are true.

• The roster is current — people who joined since the last run are in it, and people who left are marked as such rather than silently screened forever.
• The result is recorded with the date of the source data, not just the date of the run. 'Screened in August' is meaningless without 'against the file published August 10'.
• A source that could not be checked is recorded as unchecked. A month in which a source failed and was reported as clean is worse than a month that was skipped, because it looks like evidence.

NPISignal's monitoring product exists for those three properties in particular. The screening itself is the easy part; keeping a year of it defensible is what takes a system.
