It covers "Activities of Daily Living" such as feeding, bathing, toileting, dressing. The need has to be certified by the patient's MD. Unfortunately, most MD's have no idea what is being done for the patient at home.

If you hand him a blank form I guarantee his office staff (who know even less) will mess it up.
