Medicaid Pending Resident Accounting on Cost Reports

Medicaid pending status, the condition of a resident admitted to a skilled nursing facility while an eligibility determination is still working its way through the state agency, is an accounting condition that touches the receivable, the revenue recognized against it, and the patient-day statistics that feed the cost report, all at once. This article walks through each of those touchpoints in order: how the receivable should be valued, how patient days should be classified before eligibility resolves, what the redesigned CMS-2540-24 form changes about visibility into these errors, how the errors flow into per-diem rates and settlement, what facilities can do during the pending window itself, and finally how auditors and lenders test all of it.

Why Medicaid pending residents create an accounting problem that runs through the entire cost report

A resident admitted while a Medicaid application sits unresolved creates an immediate mismatch between the service delivered and the payer who will eventually be billed for it. But the economic substance of that admission, assuming the application is approved, is a Medicaid resident from day one. The amount the facility can actually expect to collect is the Medicaid rate, regardless of the rate printed on the invoice.

That mismatch does not stay contained to a single line item. Amounts earned but not yet received have to land in the correct period. Applied to a pending resident, this means revenue must be accrued at the net amount expected from Medicaid, not deferred until the determination letter arrives, and not recorded at the gross private-pay rate just because that is the number on the bill. Get that accrual wrong and the error does not stay on the balance sheet. It travels into revenue, into net assets, and, because patient days are the basis for per-diem calculations, into the statistical side of the cost report as well.

If eligibility is ultimately denied, the facility faces a second and separate risk: the entire balance becomes potentially uncollectible, since there is no Medicaid payer standing behind it after all. CUT

How receivables for pending residents should be classified and valued on the balance sheet

The receivable for a Medicaid pending resident belongs on the balance sheet at the expected Medicaid rate, not at the private-pay rate the claim was billed under. Carrying the full billed amount as an asset, without that allowance, overstates both revenue and net assets starting from the resident's first day in the building, because the facility was never realistically going to collect the private-pay rate from a resident whose Medicaid application is expected to succeed.

Two distinct reserves do two distinct jobs here, and conflating them is where a lot of the trouble starts. A facility with a low historical denial rate and a population of pending accounts that are relatively recent needs a different reserve than one with a much higher denial rate and accounts that have been aging far longer.

Accounts that age past the point where a determination was reasonably expected start to look less like Medicaid pending and more like unresolved private-pay balances heading into the 90-day-plus bucket, and incomplete patient-day reconciliation paired with AR discrepancies of this kind are among the most common triggers for audit concern.

The two possible outcomes each demand their own accounting response, and neither is optional. That refund obligation becomes a liability the moment the approval comes through, requiring immediate action rather than later cleanup. When eligibility is denied instead, the facility should remove any Medicaid contractual allowance from the books. The full balance has to be re-evaluated as a private-pay account, and in many cases the allowance for doubtful accounts needs to increase materially to reflect the real collection odds on what is now a private-pay receivable.

Reporting patient days by payer when eligibility is unresolved at year-end

The same uncertainty that forces a contractual allowance onto the receivable also forces a decision about how to classify the resident's patient days while no determination exists. A Medicaid pending resident at fiscal year-end has no confirmed payer column to sit in, and how the facility handles that gap in the interim has a direct effect on the per-diem cost calculation and on reimbursement settlement down the line.

Mississippi Medicaid's cost report instructions define a resident as Medicaid-only when Medicaid is the primary payer for that specific day. A pending resident, by definition, does not meet that test yet, which leaves a genuine classification gap in the patient-day statistics rather than a clean answer either way. How exactly should a facility treat a day of care for a resident it reasonably expects Medicaid to approve, but hasn't yet?

The practical risk runs in one direction more than the other. If pending days get parked in a catch-all "Other" or private-pay column simply because that is where they fit administratively, the Medicaid patient-day total for the period ends up understated. Since many states derive the Medicaid per-diem rate from exactly this kind of patient-day data, an understated total can suppress the rate the facility is working to justify and can undercount Medicaid utilization in the models state agencies use for rate-setting. The error is not symmetric. A facility that misclassifies pending days almost always does so toward understatement, because the default administrative path is to put undetermined residents wherever the "no payer confirmed yet" bucket happens to be.

Retroactive approval compounds the problem further. None of this is manageable without a record. Facilities need a running log of pending residents that tracks admission date, expected determination date, and payer classification as of each reporting cutoff. Without that log, there is no defensible basis for the classification used at year-end, and no reliable way to go back and restate correctly once a determination finally arrives.

What CMS-2540-24's payer-segregated reporting structure means for pending-resident misclassification

The redesigned SNF Medicare cost report, Form CMS-2540-24, applies to cost reporting periods ending on or after September 30, 2025. Its structure matters here because it takes the exact classification gap just described, the one that used to be absorbable into a loosely defined "Other" category, and removes the place where it could hide.

Worksheet S-3, Part I now requires Medicare Advantage and Medicare HMO days, admissions, and discharges to be reported separately from Medicaid HMO statistics. Worksheet G-2 separates revenue for room and board and ancillary services by payer type, so a facility that has been carrying pending accounts in an undifferentiated revenue column now produces a reconciliation gap that appears as a direct mismatch an auditor or the Medicare Administrative Contractor can flag without much digging.

The structural shift goes further than adding new lines. Medicaid and Medicaid HMO census statistics must now be reported separately under the new form, and Medicare HMO is reported on its own rather than grouped with "Other" payers. The category that used to absorb an unresolved pending-day classification simply is not available anymore in the same way.

CMS maintains all of this data in HCRIS, the Healthcare Provider Cost Reporting Information System, and the CMS-2540-24 data series is already active for fiscal years beginning in 2024 and ending through 2026. Payer-level inconsistencies that might once have blended into a facility's own internal numbers are now part of a structured data set CMS can examine across the entire sector, not just within one provider's filing history. There is no transition period to lean on, either. Facilities cannot choose between CMS-2540-10 and the new form; fiscal-year filers are already moving through the changeover, and it arrives for calendar-year operators at their next year-end. A receivable misclassification or patient-day error that the old form's broader categories might have smoothed over now lands in a specific worksheet, in a specific line, where it is far easier to trace back to its source.

Effects on Per-Diem Cost Calculations and Reimbursement Settlements

Because many states calculate Medicaid reimbursement rates directly from cost report data, the errors described in the two prior sections do not stay theoretical. They feed straight into the per-diem calculations that determine what a facility gets paid in future periods, not just what it reports for the period just closed.

The mechanism is fairly direct. Patient days sit in the denominator of the per-diem cost calculation. If the Medicaid patient-day count is understated because pending residents were left in the wrong column, that denominator shrinks, and the apparent cost per Medicaid day rises as a result, since the same total costs are now being divided across fewer days. That can trigger settlement adjustments or rate corrections that move in a direction the facility did not anticipate and would not welcome. A single pending resident misclassified for a few weeks might not move the number much. A pending population of thirty or forty residents, tracked incorrectly across an entire fiscal year, can shift the per-diem calculation by a margin that matters at settlement.

Inaccurate or incomplete cost report data can lead to payment delays, recoupments, or audit findings, and Medicare settlement data exists specifically to reconcile overpayments and underpayments after the fact. A classification error made during the pending window does not vanish once the cost report is filed. It resurfaces later as a settlement discrepancy, at which point correcting it is a far more involved process than getting it right the first time would have been.

Related-party cost allocations complicate the picture further. The pending-resident error does not just distort the Medicaid per-diem rate directly. The same pending-resident error also distorts the cost allocation math that sits underneath several other lines of the same cost report.

Requirements During the Pending Window

Every error traced through the sections above has the same root cause: pending status gets tracked loosely, or not at all, until someone has to reconcile it at year-end under time pressure. Preventing that requires treating eligibility status, payer transitions, and patient-day classification as a discipline maintained continuously from the date of admission.

The core tool is an admission-level log, and it needs to capture five specific data points for every pending resident: the date of admission, the date the Medicaid application was submitted, the expected determination timeline, the provisional payer classification currently used in the general ledger, and the date and outcome of the eligibility determination once it arrives. That log is what makes the year-end patient-day classification described earlier defensible, and it is what makes a retroactive restatement possible to execute accurately rather than reconstructed from memory months after the fact.

The contractual allowance needs updating continuously as the pending population ages. An account still unresolved well past the facility's typical determination window carries materially higher denial risk than one still within the normal range, and the allowance for doubtful accounts should move to reflect that. When a determination finally comes through, whether approval or denial, the accounting response needs to happen close to immediately: restate the receivable, adjust revenue, book or release the relevant allowance, and update the patient-day log for the affected period. Letting that work pile up only makes the eventual year-end reconciliation harder, since every delayed update becomes one more adjustment to untangle all at once instead of one handled in the period it actually occurred.

The same discipline, applied monthly to the pending-resident population specifically rather than just at the broad census level, is what keeps that reconciliation from becoming a backlog that only gets confronted once a year.

How Auditors and Advisors Evaluate Medicaid Pending Accounts

Everything built up through the pending window eventually meets outside scrutiny, and the test applied there is fairly consistent. A financial statement auditor's central question about Medicaid pending accounts is whether management's allowance methodology holds up under examination: do the assumptions about approval rates, expected Medicaid rates, and aging thresholds actually match the facility's own historical experience, and are they applied the same way across the whole pending population rather than adjusted case by case to produce a more favorable number.

Auditors also confirm that the patient-day statistics reported on the cost report tie out to the census log and the general ledger. A mismatch between how a resident is classified in the billing system and how that same resident appears on the cost report is one of the more common findings auditors raise, and the payer-segregated structure of CMS-2540-24 makes that kind of mismatch considerably harder to obscure than it was under the prior form.

The scrutiny extends past the audit itself. HUD Section 232 financing is a significant source of capital for skilled nursing facility properties, and an understated allowance on Medicaid pending accounts inflates the EBITDA and net asset figures a facility presents to its lender. That is a material representation risk, not a minor valuation quibble, and lenders along with their auditors treat the pending population as a standard part of underwriting and ongoing covenant monitoring rather than something reviewed once and set aside.

Tax advisors working with closely held SNF operators face a related but separate problem: a timing mismatch between what gets recognized for GAAP purposes and what appears on the tax return. Revenue may be recognized in one tax year at the private-pay rate, then reversed in a later year once retroactive Medicaid approval brings that revenue down to the actual Medicaid rate. That reversal widens the gap between accrual-basis financial statement income and taxable income, and it is one more reason the accounting choices made during the pending window, however administrative they may look in the moment, carry consequences that reach well past the facility's own books.
