The only changes) to look out for is whether your State is under fed medicaid or self funded, and check with your doctors on whether or not they accept the secondary medicaid. that changes year to year and they do not always tell you. it has to do with any medicaid reimbursement rate changes.
medicare will be primary, and depending on whether or not it is a disability award, you will pay the part a and part b 80% medicare coverage cost out of your ss check, which is 107/month +/-. again, depending on the medicare award, you may have to pay the yearly deductible that everybody on medicare pays, which is about 173/year. very cheap.
the supplemental part b 20% will be paid by medicaid. also check on part d prescription coverage, which you may have to pay part of, depending on how the medicaid was awarded. i know. i know because i have been through it many times.
