PDPM Interrupted Stays: When the Payment Clock Starts Over

PDPM interrupted stay fraud can involve falsifying discharge dates, return dates or facility identity to restart Medicare’s payment schedule. A resident who resumes covered care at the same skilled nursing facility within the interruption window continues the previous schedule. A false restart makes Medicare pay for a fresh start that never happened.

The Patient Driven Payment Model replaced therapy-minute groups with classifications based on resident characteristics and clinical needs. Some payment components also change with the day of the stay. That makes the date on a discharge record financially important: a new beginning can bring back higher rates. For an MDS coordinator, nurse or billing employee, the question is whether the dates and facility on the claim match what actually happened to the resident.

Does SNF Readmission Within Three Days Restart PDPM Payment?

SNF readmission within three days does not restart PDPM payment when the resident resumes Part A-covered care at the same skilled nursing facility inside the interruption window. The window starts on the calendar day of Part A discharge, the first non-covered day, and includes the next two calendar days. It ends at 11:59 p.m. on the third day.

The assessment manual from the Centers for Medicare & Medicaid Services treats that return as a continuation for both the payment schedule and the assessment schedule. No new five-day payment assessment is required. The variable per diem schedule, which adjusts selected daily payment components as a stay progresses, resumes where it stopped.

The manual gives a useful example. A resident enters the skilled nursing facility on November 7, 2019, transfers to a hospital on November 20 and returns to the same facility on November 22. Payment continues from day 14, the day of discharge. The hospital trip has interrupted the stay without creating a fresh payment schedule.

In another example, the resident returns to the same facility on November 25 after the same hospital-transfer date. That return falls outside the window and starts a new payment stay, with a new five-day assessment and day-one rates. Admission to a different skilled nursing facility also starts a new payment stay, even when it occurs within the window.

Part A discharge also has a meaning beyond leaving the building. A resident can stop receiving Part A-covered services, remain in the facility and resume covered care within the window. The interruption rule applies to that situation too. The decisive facts are the end and resumption of covered care, the timing and the same-facility requirement.

Which Discharge Assessment Marks an Interrupted Stay?

An interrupted stay does not require a Part A PPS Discharge assessment. When the resident physically leaves the facility and returns within the window, the separate OBRA Discharge assessment records that departure. If covered care stops and resumes within the window while the resident stays in the building, neither discharge assessment is required. An OBRA discharge on the record therefore does not, by itself, mean the Medicare payment stay ended.

Does an Interim Payment Assessment Reset the PDPM Day Count?

No. An interim payment assessment can change the payment classification, but it does not reset the PDPM day count or the variable per diem adjustment schedule. Its payment effect begins on the assessment reference date, the endpoint of the assessment’s observation period.

The interim payment assessment is optional. The manual allows clinicians to complete one after an interrupted-stay return while continuing the existing payment schedule. A resident’s changed condition can therefore reach the payment calculation without making the return a new stay.

That distinction matters when a billing explanation points to a new assessment. The assessment can support a different classification from its reference date. The discharge and return records still determine whether the day count continues. Calling the assessment new does not make the payment clock new.

PDPM Interrupted Stay Versus Medicare Benefit Period Reset: Separate Clocks

An interrupted stay and a Medicare benefit period run on separate clocks. The interruption rule decides whether the payment schedule continues or starts over. The benefit period governs the resident’s available Medicare-covered nursing facility days.

Medicare covers up to 100 skilled nursing facility days per benefit period, with coverage requirements applying throughout. The benefit period ends after at least 60 consecutive days outside inpatient hospital care and skilled care in a nursing facility. Remaining in a nursing home for custodial care alone does not keep the benefit period open.

A new PDPM payment stay does not create another allotment of benefit days. A return can restart the facility’s payment schedule while drawing on the resident’s remaining days in the existing benefit period. The billing record needs to account for both.

Nursing Home Discharge and Readmission to Restart NTA Payment

A nursing home discharge and readmission restarts NTA payment only when it creates a new payment stay under the interruption rules. An interrupted stay resumes the previous schedule. A qualifying new stay begins again at the early-stay factors.

The nontherapy ancillary component pays three times its ordinary case-mix amount on covered days one through three, then uses the ordinary amount. Physical and occupational therapy components also vary with time: their factors begin declining after day 20. A false restart can therefore change payment even when the resident’s underlying classification stays the same.

The early NTA factor applies to that component, not to the whole Medicare daily payment. PDPM combines physical therapy, occupational therapy, speech-language pathology, nursing and nontherapy ancillary components with a non-case-mix amount. Only selected components receive the day adjustment.

NTA classification asks which conditions and services the assessment supports. Interrupted-stay timing asks which day factor applies to that classification. Both reach the payment, but they leave different evidence. The clinical notes and orders support the condition or service. The discharge, return and facility records support the clock.

What Evidence Is Needed to Prove Fraud?

Evidence of a false restart connects the resident’s actual discharge and return with the assessment, day count and paid claim. The strongest comparison also shows who chose the disputed information and what they knew when the facility used it.

We examine the transfer and discharge records beside the hospital and nursing facility claims. The dates show when covered care stopped and resumed. The certified provider’s identity shows which facility furnished it. That comparison matters because a same-facility return and admission to another facility can receive different treatment even on the same dates.

The MDS versions and any IPA then show the assessment inputs and reference dates behind the classification. Contemporaneous nursing notes, therapy notes, diagnoses and orders supply the clinical comparison. The HIPPS code carries the payment classification into the claim. The payment record shows which classification and day factors Medicare actually paid.

Original and changed records matter together. A date that moved, a changed facility identifier or an assessment revised after a transfer needs to be connected to the claim that used it. We examine who made the change, the reason given and any correction to the resulting payment. That is how a discrepancy in the chart becomes a specific question about money paid by Medicare.

What Is a Red Flag for Health Care Fraud?

A return date that contradicts the transfer records and moves the claim into a fresh payment schedule is a specific red flag. So is a different facility identity used to obtain new-stay treatment when the resident actually resumed care at the same SNF.

The question is whether someone knowingly made the claim describe a new stay that the resident’s records do not support. A healthcare employee who understands the change can connect the billing result to the decision behind it.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

Pinnacle Shows Why the Paid Claim Must Match the Chart

The Department of Health and Human Services Office of Inspector General published its audit of Pinnacle Multicare Nursing and Rehabilitation Center in November 2025. Reviewing claims from 2020 and 2021, the Inspector General found unsupported HIPPS codes in 95 of 100 sampled claims.

One NTA example concerned a classification based on a need for intravenous medication. The Inspector General found that the medical records described treatment that did not require it. The diagnosis, treatment and paid classification had to support the same account of the resident’s needs.

The Inspector General extrapolated its sample findings and recommended a $31,227,884 refund. Pinnacle disputed the findings.

For an interrupted-stay concern, the comparison adds another payment input: the day of the stay. A supported diagnosis can still sit beside a disputed restart date. The useful evidence connects both to the amount paid, then to the people who supplied or changed the information.
