State Medicaid agencies and their program integrity contractors are auditing home and community based services delivered under 1915(c) and 1915(k) waivers against whether the service billed matches what the person-centered plan of care authorized. When it does not, the state does not need to prove fraud to recover the payment. A gap between the plan of care, the level of care assessment, and the provider's service note is enough to support a recoupment across the full audit period.
Plan of Care Alignment Is the Federal Audit Standard
Federal regulation requires that HCBS furnished under a 1915(c) waiver follow an individualized, person-centered service plan reflecting the person's assessed functional needs, preferences, and identified goals. Under 42 CFR 441.301(c)(3), the plan must be reviewed and revised at least once every 12 months, whenever the individual's circumstances or needs change significantly, and at the individual's request. Community First Choice programs authorized under 1915(k) carry a parallel person-centered service plan requirement at 42 CFR 441.540, plus a continuous quality assurance system that includes mandatory reporting of abuse, neglect, and exploitation allegations under CMS guidance on the Community First Choice option. Auditors line up the plan on file against the claims submitted for the same period.
What State and Federal Audits Have Found
A 2016 OIG review of state HCBS waiver programs found at least $176.5 million in unallowable and unsupported federal Medicaid reimbursement, largely because state agencies had not excluded room and board costs from HCBS payment rates before billing the federal government. A later OIG audit of New York's Bridges to Health 1915(c) waiver sampled 100 of 105,703 beneficiary-months claimed between calendar years 2015 and 2017, covering $149 million in federal reimbursement. Eight of the sampled months were noncompliant: four because the billed services did not align with the approved plan of care, three because provider documentation did not substantiate the services claimed, and one because the services conflicted with the individual's approved level of care assessment. A separate review of 32 sampled months found services billed above the monthly allotment the plan of care authorized, which OIG estimated at $3.3 million in overpayments on top of a recommended $614,530 refund for the noncompliant months.
The Records a Waiver Provider Needs to Defend a Claim
The plan of care, the current functional or level of care assessment, and a contemporaneous service note for each billed unit are the records an auditor requests first. A note documenting the date, the duration, the specific service delivered, and the identity of the attendant or provider who delivered it is what ties a claim back to the plan of care it billed against. Providers billing under a 1915(k) Community First Choice program carry the added burden of showing that attendant care or personal care services match both the plan and the individual's assessed need, since CFC's quality assurance obligations put state reviewers on notice of any gap. Where the same waiver services are delivered through a Medicaid managed care organization rather than fee for service, the plan's own audit standards can apply on top of the state's. A documentation gap found during an HCBS audit can also trigger a payment suspension under 42 CFR 455.23 once the state agency determines it has a credible allegation of fraud, freezing payments before the underlying dispute is resolved.
A plan of care that does not match the claim becomes a recoupment before the audit ever reaches the service note.
Why Early Legal Counsel Is Critical
It is critical that HCBS providers and their compliance officers promptly retain experienced healthcare defense counsel upon receiving a waiver audit notice, a request for plan of care documentation, or a payment suspension letter. Early legal intervention can shape the initial document production, preserve the plan of care and service note records the audit will turn on, and position the provider to pursue a Medicaid fair hearing or a formal audit appeal rather than accept a recoupment finding. A pattern of unsupported claims that a state agency treats as more than an isolated billing error can also draw False Claims Act exposure or an OIG exclusion referral, both of which raise the stakes well beyond the disputed reimbursement. Delaying counsel until after the exit conference narrows the options that were available when the audit opened.
