What is the difference between durable power of attorney and medical power of attorney?

A general (or limited or specific) power of attorney gives the attorney in fact the power to handle the financial affairs (but not medical decisions for) of the grantor.

A medical (or health-care) power of attorney gives the attorney in fact the power to make medical decisions for (but not handle the financial affairs) of the grantor.

The word "durable" on any power of attorney means that the power of attorney will not become invalid if the grantor is mentally or physcially incapacitated.

Although a medical power of attorney is also usually durable (since it would most often be needed when the grantor is incapacitated) the phrase "durable power of attorney" usually is used to describe a financial rather than a medical POA.
