A Medical Durable Power of Attorney gives one (called the attorney-in-fact) the authority to make medical decisions for the grantor if s/he is unable to make such decisions for himself/herself. Usually, it can also grant the attorney-in-fact the ability to access the grantor's accounts and assets to pay any medical bills and fees. If you were not granted that ability in the Durable Power of Attorney, you will need to either work with the designated financial attorney-in-fact, or an attorney to be able to pay his medical expenses.
