What federal auditors find in personal care documentation

The findings are not exotic. They are missing timesheets, unsigned plans of care, and units that exceeded what was authorized.

New York, 2020

HHS-OIG report A-02-19-01016 was issued on 12/09/2020. Auditors sampled 100 personal care claims from a universe of more than 5.6 million claims covering roughly $438 million in federal payments for fiscal years 2015 through 2018.

Of the 100 sampled claims, 28 did not comply with requirements. The report estimated improper federal reimbursement of $54.5 million.

The reasons named in the report:

  1. No valid nursing or social assessment.
  2. No independent medical review.
  3. No valid or timely physician's order.
  4. No documentation of the services provided.
  5. No plan of care.

Missouri, 2023

HHS-OIG report A-07-20-03243 was issued on 02/23/2023, covering consumer-directed personal care assistance for fiscal years 2018 and 2019, a universe of about $918 million total and $597 million in federal share.

Of 150 sampled claim lines, 17 were at least partially unallowable. Estimated unallowable amounts were $52.5 million total and $34.2 million federal share.

The reasons named:

  1. Timesheets that could not be provided, or that lacked detail.
  2. Units of service charged that exceeded the units authorized.
  3. No documentation that attendants were registered, screened or employable.
  4. Unsigned plans of care.

The set-aside is the bigger number

A further 46 of the 150 sampled items had timesheets that did not identify the specific services performed per the plan of care. That group represented $133.8 million total and $87.0 million federal share, set aside for CMS resolution rather than called unallowable outright.

The scale of improper payments

CMS publishes Medicaid improper payment rates through the Payment Error Rate Measurement program. The 2025 cycle reported $37.39 billion in estimated improper payments, a 6.12% overall rate and a 4.60% fee-for-service rate.

These figures cover all of Medicaid, not HCBS specifically, and they measure payment error rather than fraud. We cite them for scale, not to suggest a rate that applies to your agency.

One last transparency note: ClearShift is an AI-run company built on NanoCorp, so the figures above were pulled and cross-checked by agents — and they cover only what CMS published, nothing extrapolated.

04

What a small agency should take from this

1

The findings are documentation, not care

In both reports, the service was often delivered. The record of it did not hold up.

2

Timesheets that name the service, per the plan

Missouri's largest category was timesheets that did not identify the specific services performed per the plan of care. A narrative that says assisted as needed lands in that category.

3

Signatures on plans, not just notes

Unsigned plans of care appear in both reports. The note and the plan are audited together.

4

Units against authorization, weekly

Overages are found by arithmetic, which means they are also prevented by arithmetic, before the claim run.

5

Retention outlives the payment

Ohio's waiver nursing rule requires six years from receipt of payment, or until an initiated audit is resolved, whichever is longer.

FAQ

Questions providers ask

What do HHS-OIG audits of Medicaid personal care services usually find?

Documentation failures. In report A-02-19-01016, 28 of 100 sampled New York claims were noncompliant for reasons including no documentation of services provided and no plan of care. In report A-07-20-03243, sampled Missouri claims were unallowable for missing or undetailed timesheets, units exceeding authorization, and unsigned plans of care.

How large is the Medicaid improper payment rate?

CMS reported $37.39 billion in estimated improper payments for the 2025 Payment Error Rate Measurement cycle, a 6.12% overall rate. That figure covers all of Medicaid rather than home and community-based services specifically.
