How often is Plan of Care revised?

Mom moved into AL in June and 2 weeks later was sent to hospital for pain, diagnosed with terminal illness sent back with hospice care. We needed plan of care for additional agency hired to help through nights. The plan of care still lists escort to dining room, showers, grooming; none of the listed have actually been happening. Mom is actively dying and has been bed bound since. Hospice care took over all hands on care but actually administering comfort meds. Our bill has not changed.
