Medi-cal (medicaid) and really crappy work insurance

57 and 58 year old couple in california. In california medicaid, is called medi-cal We had medi-cal (medicaid) during the pandemic.. and then my husband got a job. His work insurance covers me also, but i havent actually applied yet, and it has extremely high co-pays. It also does not cover my specific prescription drug at all, and id have to pay out of pocket. ($4,000-$5,000 per month) which is literally his entire income before taxes. Ive tried calling LITERALLY all day 7am-8pm yesterday… again 7am-5pm today.. and havent been able to get any answers.

Question: Can we have both medi-cal, and my husband work insurance? do i have to cancel medi-cal? If he has his work insurance, and i dont apply to his work insurance, can i keep my medi-cal? I really dont know what next steps to take. i dont want to do anything illegal, but the medication i need is extremely expensive, and i can not afford it without medi-cal at the moment.. no one im calling is giving me straight answers or what my next steps are..

please and thanks for any help.
