What this specialty covers

An internist who has special knowledge of the aging process and special skills in the diagnostic, therapeutic, preventive and rehabilitative aspects of illness in the elderly. This specialist cares for geriatric patients in the patient's home, the office, long-term care settings such as nursing homes and the hospital.

Reading the sole-proprietor share

For this specialty, 987 records, or 17.0%, are flagged as sole proprietors in NPPES. The flag is a self-reported NPPES field, so it is an imperfect proxy for private practice and does not by itself establish ownership, employment arrangement, or whether the clinician practices independently.
