What does the Medicare cost report certification actually require a signer to attest to?

The chief financial officer or administrator who signs the cost report certifies, to the best of their knowledge and belief, that the report is true, correct, complete, and prepared from the provider's books and records, and that the services identified in the report were provided in compliance with applicable laws and regulations. The form also warns that misrepresentation or falsification of any information in the cost report may be punishable by criminal, civil, and administrative action under federal law.

Can a former employee file a qui tam complaint over a Medicare cost report?

Yes. A relator with inside knowledge of how a cost report was prepared, such as a former compliance officer, billing consultant, or finance employee, can file a qui tam complaint naming the cost report certification as the false statement. The complaint is filed under seal while the government investigates and decides whether to intervene. A hospital, home health agency, or nursing facility named in such a complaint should retain healthcare defense counsel before responding to any related document request.

Cost Report Errors as False Claims Act Exposure

Q: Can an honest mistake on a Medicare cost report lead to False Claims Act liability?

No. Civil False Claims Act liability under 31 U.S.C. Section 3729 requires that the certifying officer acted knowingly, meaning with actual knowledge of the false information, deliberate ignorance of its truth or falsity, or reckless disregard of its truth or falsity. The statute does not reach ordinary negligence or a good-faith error in a cost allocation methodology. The government or a relator still has to prove the certifying officer's state of mind when the cost report was signed.

A hospital, home health agency, or nursing facility submits a Medicare cost report every year, and the chief financial officer or administrator who signs it is certifying far more than arithmetic. The Centers for Medicare & Medicaid Services requires that signer to attest, under a warning of criminal, civil, and administrative penalties, that the report is true, correct, and complete. When that certification turns out to be knowingly false, the cost report becomes a potential predicate for civil False Claims Act liability.

The Cost Report Certification

Worksheet S of the hospital cost report, Form CMS-2552-10, and the equivalent certification page on the home health agency cost report, Form CMS-1728-20, carry the same warning: misrepresentation or falsification of any information in the cost report may be punishable by criminal, civil, and administrative action, fine, or imprisonment under federal law, and the same consequences apply to kickback-tainted or otherwise illegal services. The certifying officer then affirms, to the best of their knowledge and belief, that the report is true, correct, complete, and prepared from the provider's books and records, and that the reported services complied with applicable laws and regulations. A False Claims Act theory attaches to that affirmative statement, not to the underlying cost data alone.

Common Errors That Create Exposure

The errors that turn a cost report into an enforcement target are substantive, not clerical: misallocating costs across cost centers to inflate reimbursable expense, omitting related-party transactions from the home office cost statement, overstating bad debt, or miscounting the statistics used to apportion costs each misstate figures the certifying officer represented as true and correct. Cost reports sit alongside risk adjustment submissions as another filing that can carry False Claims Act exposure. Contractors check the filed report against claims data, audited financial statements, and prior-year filings before CMS finalizes it through the Notice of Program Reimbursement.

The Knowing Standard Under the False Claims Act

Civil liability under the False Claims Act, 31 U.S.C. Section 3729, attaches only when the certifying officer acted knowingly. Section 3729(b)(1) defines knowing to mean actual knowledge of the false information, deliberate ignorance of its truth or falsity, or reckless disregard of its truth or falsity, with no proof of specific intent to defraud required. The Act does not reach ordinary negligence or a good-faith error in a complex cost allocation methodology. The government or a relator still has to show the certifying officer's state of mind when the report was signed, and that the false statement was material to CMS's payment decision under the Section 3729(b)(4) definition of material.

A cost report that is wrong is not automatically a false claim. False Claims Act exposure turns on what the certifying officer knew, or recklessly disregarded, when the certification was signed, not on whether the cost allocation later proves incorrect.

From Certification to Qui Tam Claim

A cost report certification can become the basis of a qui tam complaint filed by a relator with inside knowledge of the report's preparation, such as a former compliance officer, billing consultant, or finance employee. Filed under seal, the matter proceeds through the investigation stage covered in Inside an FCA Investigation: The Defense Timeline before the government decides whether to intervene. A provider that finds a misstatement and does not correct it faces a separate theory: knowingly retaining an identified overpayment can itself support a reverse false claim, addressed in Reverse False Claims Liability for Retaining an Overpayment. A cost-report resolution can also carry a corporate integrity agreement and put the certifying individual at risk of OIG exclusion from federal health care programs.

Why early legal counsel is critical: hospitals, home health agencies, and nursing facilities should retain experienced healthcare defense counsel promptly after discovering a cost report error or receiving a qui tam complaint, a civil investigative demand, or any other sign of a cost-report-based False Claims Act inquiry. Early legal intervention protects the provider's rights, guides how an error gets corrected or disclosed, preserves defenses before litigation positions harden, and lets counsel communicate with investigators and contractors on the provider's behalf. Delaying representation narrows the defenses available later and can affect how a knowing-standard dispute resolves.
