call MediCal I have no idea if claiming them as a dependent would affect MediCal.
but first determine if you can claim them as a dependent.
you can claim them as a qualifying child if all these tests are met
• they have the same principal abode as you for more than ½ the tax year. Temporary absences like for school are ignored
• if they are not a full-time student, they're under 19 at the end of the tax year. If a full-time student, they're under 24 at the end of the tax year.
• they haven’t provided over ½ their own support
• they didn't file a joint return unless there was no tax liability but merely filing joint to facilitate refund of taxes withheld or estimates paid
or you can claim them as a qualifying relative if all these tests are met
• their gross income for 2022 is less than $4,400
