SSI Medi-Cal: re-enroll only if SSI benefits are discontinued

If you continue to receive SSI benefits, you do not have to renew your enrollment. But if your SSI benefits are discontinued, the Human Services Agency (HSA) of San Mateo County will mail you an eligibility packet for County Medi-Cal. Complete the forms in the packet and return to HSA. You will be enrolled in County Medi-Cal if you are eligible.
