California secures guilty plea and prison sentence in $400,000 Medi-Cal fraud case
Sep 27, 2026 edition · GC-2026-0131 · Published 2026-09-27 · Version 2 · Final
California announced a guilty plea and two-year prison sentence in a $413,643.30 IHSS and respite-care fraud case involving false claims about a disabled family member's care.
What happened
California's Attorney General announced September 21, 2026 that Maki Martinez-Gruninger pleaded guilty to one felony count of Medi-Cal false claims and would serve two years in state prison. The investigation identified $413,643.30 in false IHSS and respite-care claims. The case involved a disabled family member whose actual caregiver reported discovering the scheme. This is a criminal resolution, rather than an unresolved civil allegation or an administrative audit.
According to the release, the complainant discovered in December 2019 that Martinez-Gruninger had secretly applied in November 2007 to act as the family member's IHSS provider. The resulting false claims continued for more than a decade. The Attorney General reports that investigators found intentional taking of Medi-Cal funds and presentation of false claims. Those details point to service-provider identity, enrollment and verification of who actually delivered care. Family relationships should not substitute for independent confirmation of provider status and delivered services.

Why it matters
Long-running personal-care fraud can depend on inaccurate provider enrollment and weak confirmation of the actual caregiver, even within a family.
Recommended action
Review IHSS or respite provider enrollment, beneficiary/caregiver confirmation and service documentation. Escalate conflicting caregiver identities or claims inconsistent with actual care and preserve an independent reporting route.
