Does Medicare pay for any home care for basic care for 85-yr-old who lives at home?

If he has less than $129,000 in assets (home and car don't count), moderately low income, and is a veteran with at least 1 day active duty during a 'war' he would qualify for VA aid and attendance. You can hire someone to get you through the process. At his age, for example, if he was in the Korean or Vietnam war he would qualify.

If they are low income they may be able to get Medicaid in home health. Your local Office of Aging should be able to help with resources.

No, unfortunately. You need to hire a private agency.
