PDPM NTA Upcoding: Diagnoses, Treatments and the First Three Days of Payment

PDPM NTA upcoding inflates Medicare Part A payments by putting unsupported conditions or services into a skilled nursing facility’s assessment. The assessment supplies the payment classification, so a change on the Minimum Data Set assessment can become a change in what Medicare pays. The inflated assessment leaves Medicare paying for care needs the chart does not support.

If you work in nursing, assessment or billing, you may see the gap between the resident’s care and the condition entered for reimbursement. That gap is where we start: what the chart supported, what the facility submitted and who chose the entry.

How NTA Points Become Medicare Payments

NTA means nontherapy ancillary. Under the Patient Driven Payment Model, qualifying conditions and extensive services carry weighted points that determine the resident’s NTA payment group. A diagnosis entered on the MDS can therefore affect money as well as the care record.

The Patient Driven Payment Model replaced RUG-IV for covered Medicare Part A skilled nursing stays on October 1, 2019. The older system tied therapy classification to minutes. PDPM uses resident characteristics and clinical needs across physical therapy, occupational therapy, speech-language pathology, nursing and NTA, with a separate payment component for costs outside those resident-specific groups.

The CMS assessment manual places NTA scores into six bands: zero, one to two, three to five, six to eight, nine to eleven, and twelve or more. The payment question is which group the supported points actually produce. We compare the group’s calculation with and without the disputed entry, then follow the result to the claim.

The fourth character of the HIPPS code represents the NTA group. That code appears on the Medicare claim. The connection is specific: the clinical entry feeds the assessment, the assessment feeds the group, and the group feeds the billed rate.

The PDPM First Three Days NTA Multiplier

The PDPM first three days NTA multiplier magnifies the payment effect of an unsupported diagnosis that raises the NTA group. For those covered days, Medicare pays three times the ordinary NTA base amount adjusted for the resident’s group. The ordinary NTA amount applies afterward.

The factor applies to the NTA component of the daily rate. The facility’s full payment combines the other components and applicable adjustments, including geographic wage adjustments.

That puts the admission record and early assessment at the center of the inquiry. A condition entered near admission can affect the most heavily weighted NTA days. We connect the clinical support, assessment date, submitted code and payment before putting a value on the disputed entry.

What Are the Documentation Requirements for Skilled Nursing Facilities?

The health care record must support the resident’s condition, care needs and services represented in the assessment used for payment. The Minimum Data Set brings that information together. The underlying hospital records, practitioner orders, nursing observations and treatment documentation explain why an entry belongs there.

The assessment is a shared clinical task. A registered nurse conducts or coordinates it and certifies completion. Each contributor certifies the accuracy of the portion completed. That division matters when the nurse who observed the resident, the person entering a condition and the person approving the assessment have different accounts of what happened.

NTA conditions added to MDS without documented treatment raise a specific records question: what supports the condition or service being claimed? For an IV-medication entry, the comparison includes the medication order and administration record. For a diagnosis-based entry, it includes the clinical notes showing whether the condition was active during the applicable lookback period.

We compare the hospital and admission material with the facility’s clinical notes, the original and changed MDS assessments, and the resulting HIPPS codes. The claim and payment history show whether the change reached Medicare and affected reimbursement. A correction trail or an instruction to change an entry can explain why the assessment departed from the care record.

The Assessment Date Determines Which Records Matter

The assessment reference date anchors the period being assessed. The initial five-day Medicare payment assessment uses a reference date within days one through eight of the stay. Its lookback rules determine which observations, diagnoses and services support particular entries.

An Interim Payment Assessment changes payment from its assessment reference date. We line that date up with the changed clinical information and the claim that used the revised classification. Coding instructions and diagnosis mappings also need to match the year of the claim.

That is why a current problem list and an older assessment can answer different questions. The relevant comparison is what the clinical record showed for the period represented to Medicare.

Pinnacle’s NTA Audit Example Turned on the Need for IV Medication

In its November 2025 Pinnacle audit, the Department of Health and Human Services’ Office of Inspector General found unsupported NTA classifications in 31 sampled claims. Pinnacle Multicare Nursing and Rehabilitation Center disputed the audit’s findings.

The auditors’ example concerned a resident whom Pinnacle classified as needing IV medication. The medical record showed active multidrug-resistant bacteria, but the auditors said the corresponding treatment did not require IV medication. The reviewers concluded that the NTA classification based on that need lacked support.

The audit examined 100 claims from 2020 and 2021. The auditors found that the medical records did not support at least one HIPPS component in 95 of them. Across Pinnacle’s claims for that period, the inspector general estimated at least $31,227,884 in overpayments for coding, coverage and documentation errors.

A separate disagreement in the same audit shows why active-diagnosis support deserves close attention. Pinnacle cited a two-part test: a qualified provider had documented the diagnosis within 60 days before the assessment reference date, and the condition affected the resident’s functioning or care during the seven-day lookback period. It argued that aphasia could meet that test even without speech therapy.

The auditors agreed that the resident had aphasia but found that the clinical record did not support an active diagnosis during that period.

For an NTA concern, the question is concrete: what condition or service raised the payment, and does the chart for the assessment period back it up?

Before PDPM, the Pressure Was on Therapy Minutes

The historical RehabCare case shows what payment targets can look like inside a facility. In January 2016, the Department of Justice announced a $125 million settlement with Kindred and RehabCare over allegations of unnecessary and inflated therapy billing under the earlier payment system.

The government’s complaint alleged that managers began with the desired reimbursement category:

The alleged sequence was backward: choose the payment category, then push the care toward it. In an NTA inquiry, we examine whether someone similarly chose a desired classification and pushed unsupported conditions or services into the assessment. The payment inputs changed, but the evidence comparison carries forward.

Who Chose the Unsupported Entry?

An NTA whistleblower case connects the unsupported entry, its payment effect and the decisions behind it. The employee who entered the code may hold one part of that account. A clinician who questioned it, an assessment coordinator who approved it or a billing employee who saw the resulting claim may hold another.

We examine the original assessment alongside later versions, the clinical support available at the time and the communications behind the change. If an employee raised a contradiction, the response can show whether the decision-makers understood it and allowed the claim to go forward. This is where an insider’s knowledge of the healthcare business adds something the billing data cannot explain by itself.

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

When You Know Why the NTA Score Changed

If you have seen unsupported conditions added to assessments or clinical objections overridden, speak to one of our whistleblower experts about why the NTA score changed. We work beside you to turn that inside knowledge into a case grounded in the care records, payment classifications and people controlling them. We bring in Medicare fraud whistleblower lawyers who understand skilled nursing assessment and billing, and stay with you through the case.
