An 89-year-old female patient is admitted to the skilled nursing facility after being

seen in the office earlier today. The daughter brought the patient to the office. As a

part of the detailed history, conducted with the patient's daughter, it is found that the

patient was diagnosed with dementia last year. The patient was moved to this city

from Anytown so that the daughter could care for her mother. The patient is

noncontributory, and the physician relies on medical record documentation brought

in by the daughter from her mother's previous physician. Of late, the patient has

become more and more withdrawn and noncommunicative. She has wandered away

from the daughter's home twice in the last week, and on the last occasion, was

found walking on the street. After a detailed history and comprehensive

examination, it is decided that the patient will be admitted to the nursing facility

today because of senile dementia. The physician spent 45 minutes with the patient

and in preparation of the medical documentation for admittance to the nursing

facility. The medical decision making was of high complexity.
