Health Insurance Premium Reimbursements in California with GHPP and HIPR

For those who live in California and have GHPP (Genetically handicapped persons program) and HIPR (Health Insurance Premiums Reimbursement), are the reimbursements from the HIPR program taxable?

 

These reimbursements are sent to me directly via check. This program reimburses me for medical premiums that are paid by payroll deduction (pre-tax).
