PACE HOS-M Frailty Payment Evidence: From Survey Answers to Medicare Payments

Evidence of a PACE frailty payment problem connects HOS-M survey responses to the contract’s score and the Medicare payments that used it. If you work with participants, administer surveys or reconcile PACE revenue, you may know how an answer was obtained without seeing where it went next. A clinical assessment, a participant’s response and the score used for payment each tell a different part of the story.

This page follows the survey response into the payment calculation. Diagnosis submissions follow a separate path through clinical encounters, coding and risk-adjustment data. For a concern about PACE fraud involving frailty, we connect what happened during survey administration to the input Medicare used and the money the organization received.

Are Frailty Scores Simply the Team’s Clinical Assessments?

No. PACE frailty scores use contract-level HOS-M survey information about limitations in activities of daily living. The care team’s assessment, ADL notes in a chart, the survey response and the contract’s resulting score are separate records. Someone who knows a participant’s daily needs may recognize a troubling discrepancy, but following that discrepancy into payment requires the survey record too.

In its 2026 rate announcement, the Centers for Medicare & Medicaid Services explains that frailty factors account for additional costs the diagnosis-based model does not explain. The agency estimates those factors by comparing the model’s unexplained costs with counts of ADL limitations.

PACE receives prospective monthly capitation and assumes financial risk for health care across settings, including additional care the interdisciplinary team considers necessary. The care record describes what the participant needs and receives. The survey supplies a different input to what Medicare pays the organization.

The agency’s explanation also addresses dementia, which the older diagnosis model did not directly incorporate. Related conditions and demographic factors can predict some of those costs, while the frailty factors can reflect costs the diagnosis model leaves unexplained. For someone examining an organization’s payment, a participant’s diagnosis and the survey’s account of daily limitations can therefore reach different components of the calculation.

Who Administers the PACE HOS-M Survey?

The March 23, 2026 administration memorandum identifies oversight by the National Committee for Quality Assurance, sampling and support by RTI International, and two approved vendors, Center for the Study of Services and DataStat, Inc. The care team, the survey vendor and the organization receiving payment have different roles in the process.

For that administration, eligible organizations had Medicare contracts in effect on or before January 1, 2025 and at least 30 members as of February 2026 in the March enrollment file. The sample design uses 1,200 participants for larger organizations and the entire eligible enrollment for smaller ones. The selected sample and the responses returned belong beside the resulting contract score when we examine a survey concern.

The survey window runs from late July through November 2026. Vendors may not provide organizations with patient-level reports or data during collection or between administrations. If your concern involves an organization obtaining individual responses, the relevant questions include who received them, what they received and how that access compares with the applicable survey protocol.

Proxy Assistance Leaves Its Own Evidence

The Centers for Medicare & Medicaid Services allows proxy responses at the PACE participant’s discretion. In the rate announcement, the agency addresses concerns about participants with dementia completing HOS-M and describes a specific role for staff:

The participant’s choice is central to that allowance. When we examine a concern about assistance, we want to understand who answered, who requested the proxy, what staff did and which response entered the survey data. A staff member’s account and the vendor’s record can address different parts of that question.

The agency also explains why administration matters to the money. It collects survey data consistently across PACE organizations and uses self-reported ADL limitations both to calculate scores and to calibrate the factors behind them. It says that varying assistance for participants with particular conditions could disproportionately affect organizations’ scores, depending on their participant populations and which organizations provide the assistance.

That gives a survey insider a concrete issue to bring us. If you saw instructions to replace a participant’s answer with a staff assessment, we would examine those instructions, the permitted process and the response actually submitted. The payment question is what that submitted response did to the contract factor used for the affected months.

What Is the Difference Between the HOS-M Survey Year and the PACE Payment Year?

The HOS-M survey year identifies when responses were collected. The PACE payment year identifies when Medicare used the applicable frailty factor. To connect them, we need the survey administration, the resulting contract score and the payment period in which that score applied. Matching the year printed on a survey document to the year printed on a payment report skips that connection.

The administration window tells a vendor when the survey runs. The annual payment announcement tells finance staff which model and frailty factors govern a payment year. To identify which payment year a PACE HOS-M survey affects, we follow its frailty score into the payment records.

Does PACE Use the Same Risk Model as Medicare Advantage?

PACE follows its own transition to the newer Medicare Advantage risk model. For 2026 payments for participants without end-stage renal disease, the Centers for Medicare & Medicaid Services uses 90 percent of the score under its 2017 risk model and 10 percent under its 2024 model. The frailty calculation uses the corresponding blend. Other Medicare Advantage organizations use that newer model in full that year.

The final 2027 payment policy changes PACE to 50 percent of each model, with a corresponding frailty blend. For a finance employee reviewing a disputed factor, the applicable annual model belongs alongside the survey result and the payment report. The same label, frailty, can sit above calculations using different factors.

How Does the Frailty Score Enter a PACE Payment?

The 2011 PACE payment manual describes a county rate multiplied by the sum of the participant’s individual risk score and the organization’s frailty score. The applicable annual payment policy supplies the models and factors for the year under review. If a false survey input inflated the paid frailty adjustment, taxpayers would fund the difference.

The historical manual applies the frailty add-on to community and short-term institutional participants, with zero frailty adjustment for long-term institutional participants. The implementation memorandum describes updates to community versus long-term institutional status and low-income status. The participant’s payment category belongs alongside the contract score and the annual instructions when we examine the paid month.

Which Records Show That an HOS-M Input Changed Payment?

The useful evidence connects the survey process, the submitted responses, the contract factor, the applicable payment year and the paid participant-months. The vendor may know how a response was collected while finance knows which score appeared in the payment calculation.

The survey side begins with the administration and sample records, the participant or proxy response, and the data submitted for the contract. If assistance or access is the concern, the dated protocol belongs alongside the instructions and the account of what occurred. We use those records to identify the particular input in question and who controlled it.

The payment side then follows the score into actual receipts and adjustments. We examine the paid months, reconciliation and correction history with the employee who understands the organization’s revenue records.

PACE’s other funding streams need their own records. Part D drug financing has separate payment and reconciliation methods, Medicaid pays its own monthly capitation, and private payment is possible for participants without Medicare or Medicaid. A total revenue figure can combine money governed by different calculations. For an HOS-M concern, we follow the Medicare frailty component through the relevant payments.

What the Organization Did After Learning of the Survey Problem

The later decisions can matter as much as the original input. Internal warnings, investigations, correction decisions and reconciliation records can show when the organization learned of a discrepancy and what it did next. Compliance staff may know who received a warning. Finance staff may know whether an adjustment followed.

We connect those accounts to the corrected data, the payer’s adjustment and any return of money. The original response, the decision to correct it and the payment correction are separate events.

Who Holds Evidence of HOS-M Survey Manipulation?

A survey vendor employee, clinician, or finance or compliance employee may each know a different part of the response-to-payment sequence. If you encountered an instruction to supply, alter or withhold a response, we would examine who gave it, what the applicable survey process allowed, what data were submitted and whether the resulting factor affected payment.

You may know what happened to the answer without having access to the payment records. We work with that knowledge to assess the potential whistleblower case and connect it to the organization’s Medicare receipts. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
