How is a nursing facility Medicaid audit different from a Medicare audit?

A Medicaid audit of a nursing facility is run by the state Medicaid agency and looks at the MDS assessments, cost reports and resident trust fund records tied to that state's payment rules. A Medicare audit is a federal review of Medicare Part A claims, run by a Medicare contractor under rules CMS sets for the program. A facility can face both at once, on different timelines, over the same records.

What happens to a nursing facility's Medicaid rate after an MDS audit finding?

Where a state ties its Medicaid rate to case-mix data, an MDS audit finding that overstates a resident's care needs lowers the case-mix index used to calculate that rate. The state then applies the corrected, lower rate retroactively to the period the assessment covered and recovers the difference between what it already paid and what the corrected rate allows. The facility can contest the finding through its state's audit appeal process.

Can a nursing facility appeal a Medicaid cost report audit finding?

Yes. A nursing facility that disagrees with a Medicaid cost report audit adjustment has a right to an administrative appeal, but the window to file and the procedure for doing so are set by each state and differ from state to state. A facility should read its audit notice for the specific deadline and process rather than assume another state's timeline applies, and should involve counsel promptly given how narrow some of these windows are.

Nursing Facility Medicaid Audits: MDS Reviews and Cost Reports

Skilled nursing facilities enrolled in Medicaid answer to several kinds of review at once. A state Medicaid agency can examine the Minimum Data Set (MDS) assessments behind a resident's case-mix classification, audit the facility's Medicaid cost report, and check how the facility safeguards resident trust funds. Any one of these reviews can end in a retroactive rate adjustment and a recoupment demand, and the review methods differ by state. These state-agency reviews also run on a separate track from the plan-level audits that Medicaid managed care organizations conduct under capitated contracts, a distinction covered in our analysis of Medicaid Managed Care Plan Audits Versus State Audits. What stays constant is the exposure: a minor documentation gap can become a facility-wide repayment obligation with a narrow window to respond.

MDS Assessments Behind Case-Mix Rates

The Minimum Data Set (MDS) is the resident assessment instrument that the Centers for Medicare & Medicaid Services (CMS) requires every certified nursing facility to complete, under the current RAI Manual, to document a resident's medical, functional and psychosocial status. CMS built the MDS for care planning and quality reporting, and the same data also feeds payment. Not every state ties its Medicaid nursing facility rate to MDS-based case-mix data; how states pay nursing facilities varies, according to the Medicaid and CHIP Payment and Access Commission (MACPAC). Where a state uses a case-mix system, its Medicaid agency or an outside contractor reviews a sample of MDS assessments against the resident's clinical record to confirm the reported acuity level. A finding that an assessment overstated a resident's care needs lowers the case-mix index, applied retroactively to the per diem rate for the period covered.

Medicaid Cost Report Audits

Separately, a state Medicaid program that pays on a cost-based or hybrid methodology requires an annual cost report, and the agency audits a sample of those reports, on-site or by desk review, to verify the costs and statistics reported are accurate and allowable. An audit adjustment that removes an unsupported cost lowers the rate the report supports, applied retroactively across the period the report covered. Because a cost report is the facility's certification to the state, a pattern of inflated entries can raise exposure under the False Claims Act that goes beyond a civil rate correction.

An MDS assessment, a cost report entry and a resident trust fund ledger are each a separate certification to the state, and each can generate its own audit finding and its own recoupment.

Resident Trust Fund Reviews

Federal nursing home regulations, at 42 CFR 483.10(f)(10), require a facility holding a resident's personal funds to act as fiduciary: keep a full, separate accounting that precludes commingling with facility funds, purchase a surety bond or equivalent protection, and convey the funds, with a final accounting, within 30 days of discharge, eviction, or death. State survey agencies and Medicaid program integrity units check trust fund ledgers against this requirement. A shortfall found in that review is a resident-rights violation, and it can trigger a provider-agreement action separate from any rate dispute.

Rate Adjustment, Recoupment and the Appeal

Across all three review types, the state's remedy follows the same two steps: the agency recalculates the rate retroactively for the period the finding covers, then issues a recoupment for the difference between what it already paid and what the corrected rate allows. A facility may challenge an audit finding through an audit appeal; the appeal window and procedure vary by state. A facility that assumes its deadline matches another state's rule risks losing the appeal before it is heard, so the notice itself is the only reliable source for the specific deadline.

Why Early Legal Counsel Is Critical. It is critical that nursing facilities promptly retain experienced healthcare defense counsel upon receiving an MDS audit notice, a cost report audit finding, a resident trust fund citation, or any other Medicaid program integrity inquiry. Early legal intervention can protect the facility's rights, help shape an accurate and complete response to the state's request, preserve the facility's defenses on appeal, and allow counsel to communicate with the state agency on the facility's behalf. Delaying legal representation can affect the outcome of the audit and the rate dispute that follows.
