State Medicaid programs are intensifying audits of personal care services (PCS) agencies, and three categories of documentation now drive most overpayment findings: timesheet documentation, aide qualification records, and electronic visit verification (EVV) compliance. Every state Medicaid program has been required to operate an EVV system for PCS claims since January 1, 2020, under the 21st Century Cures Act, and auditors now routinely cross-reference EVV data against paid claims, attendant timesheets, and personnel files. A mismatch in any one of those records can trigger a recoupment demand or a referral for OIG exclusion proceedings against the attendant or the agency.
The Electronic Visit Verification Mandate
Section 12006 of the 21st Century Cures Act requires state Medicaid programs to use EVV for Medicaid-funded personal care services delivered during an in-home visit. CMS guidance directs states to capture six data elements for every visit: the type of service, the individual receiving it, the individual providing it, the date of service, the location where it was delivered, and the time it began and ended. A record missing any element can fail validation at the state's EVV aggregator and block the claim. Agencies that rely heavily on manual entry to correct a caregiver's missed check-in draw particular scrutiny, since a high manual-edit rate is now treated by state auditors as a fraud indicator on its own.
Timesheet Documentation Requirements
An EVV timestamp alone does not satisfy a state's documentation requirements. Auditors expect the attendant's timesheet, paper or system-generated, to independently corroborate the EVV record: the same attendant, the same beneficiary, matching start and end times, and a service type consistent with the beneficiary's approved plan of care. A November 2024 audit by the New York State Comptroller found the state had paid $14.5 billion for 82 million personal care visits, 44 percent of the claims reviewed, with no matching EVV record, plus $11.6 million in claims for visits under eight minutes. Discrepancies of that scale are what trigger a full program audit rather than a single-claim denial.
A missing timesheet or an unverified attendant record turns a routine EVV mismatch into a full program audit.
Aide Qualification Records
Federal law sets no uniform training standard for personal care attendants; each state sets its own minimum qualifications, and those requirements vary widely, from training hours equivalent to a home health aide to no training requirement at all. Every state requires proof: background check results, age and education verification where the state mandates it, and confirmation the attendant was authorized to work on the date of service. In a national review of PCS claims, the HHS Office of Inspector General found 18 percent of sampled claims improper because the agency could not document that the attendant met state qualifications, most often missing background check records (5 percent), age verification (3.5 percent), or education records (1.3 percent). Employing an attendant who turns out to be excluded from federal healthcare programs carries its own exposure; see the firm's analysis of Medicaid exclusion and termination risk.
Recent Audit Findings and Enforcement Trends
State findings mirror the federal pattern. A 2026 HHS-OIG audit of Colorado's PCS program identified $8.0 million in confirmed overpayments and $45.7 million in questioned costs tied to unverified EVV visits, missing background screening documentation, and missing service and medication plans. Many states have moved from soft EVV enforcement, flagging inconsistent records for later review, to hard-edit claims processing that denies a claim automatically when the EVV record does not match the billed visit. Agencies whose EVV compliance rate falls below the threshold most states set, often around 85 percent, risk payment holds even before a formal audit begins. Agencies that dispute a finding retain the right to pursue an audit appeal.
Why Early Legal Counsel Is Critical
It is critical that personal care services agencies and their compliance officers promptly retain experienced healthcare defense counsel upon receiving a Medicaid audit notice or overpayment demand. Early legal intervention can protect the agency's rights, ensure appropriate responses to state Medicaid program requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with auditors on the agency's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the agency to unnecessary risk.
