1. Need for isolation
A private room is medically necessary when isolation of a beneficiary is required to avoid jeopardizing their health or recovery, or that of other patients who are likely to be alarmed or disturbed by the beneficiary’s communicable disease. For example, communicable disease, heart attacks, cerebrovascular accidents, and psychotic episodes may require isolation of the patient for certain periods.
In establishing the medical necessity for isolation, the date of the physician’s written statement is not controlling, nor is the presence of a written statement. The crucial question is whether a private room was ordered by the physician because it was necessary for the health of the patient themself or that of other patients.
