All licensed nursing homes within the Commonwealth shall be under the supervision of an administrator licensed by the Board. If a licensed nursing home administrator dies, becomes ill, resigns or is discharged, the nursing home that was administered by him at the time of his death, illness, resignation or discharge may continue to operate until his successor qualifies, but in no case for longer than is permitted by the licensing authority for the nursing home. The temporary supervisor or administrator shall immediately notify the Board of Long-Term Care Administrators and the Commissioner of Health that the nursing home is operating without the supervision of a licensed nursing home administrator.
