No.  Although your husband now qualifies for Medicare, you will not qualify for Medicare until you turn 65.  If you do not have health insurance now, you can consider signing up for health insurance coverage through a Marketplace plan.  If your household income is at least 100% of the federal poverty level ($17,420 for a couple in 2022), you may qualify for premium tax credits to reduce your cost of a Marketplace policy.  If your household income is at or below 138% of poverty (about $2,000 per month for a couple in 2022), you might be eligible for Medicaid if you live in a state that has expanded its Medicaid program.
