The PCSP, IPW, and IHSS-R IHSS programs are administered at the county level by county welfare departments and at the State level by the Adult Programs Division within CDSS. The Medi-Cal Waiver Personal Care Services (WPCS) Program is administered through Department of Health Care Services. A portion of the costs for IHSS services are paid by federal funding through the Social Security Act Title XIX, Grants to States for Medical Assistance Programs, Section 1929.

Under the IHSS programs, qualified aged, blind, and disabled individuals hire providers to come to their homes and help with personal care, housekeeping, shopping, self-care procedures, meal preparation, and other daily activities. In most cases, the IHSS recipient is the employer of the provider and, as such, manages their activities. The State provides payroll services to pay the providers' wages. Twice monthly, the recipient or provider mails a time sheet to their county welfare office where the hours worked are input into CMIPS, a state-wide computer application and database. CMIPS calculates pay and taxes and sends the information to the State Controller's Office, which prints and mails the paychecks to the providers.

County welfare offices throughout California are responsible for determining recipients IHSS eligibility and service needs, and managing each case. A county social worker initially assesses an individual in their home to determine level of support required. If requested, the county or the county’s Public Authority can also help the recipient find a provider, but in many cases, family members provide the support services. Once a provider is identified, the information about the provider is entered into CMIPS for subsequent payroll processing. Every recipient must be re-assessed annually to ensure they continue to have the proper level of support.

so, what I have found is that you need to read your handbook first. Then, as it directs in the handbook, contact payroll if you believe there is something incorrect about your hours. If you cannot figure out how to contact payroll, contact your fathers case worker.
