Medicaid eliibility

You don’t COLLECT Medicare - you collect Social Security - 

Now if you are talking about Medicaid that covers medical cost and not Long Term Care -  If you two live together in the same household or file your taxes as married filing joint - have assets and resources together - then they are gonna count your income and her income to assess eligibility for MEDICAID. 

Check out the income/asset levels on how Medicaid works with Medicare based on the program.  This list is pretty correct although some states don’t count any assets - states are the ones that design their Medicaid programs..
