In ON, medical consultations with specialists like Dr. Feilchenfeld are typically covered by your provincial health insurance (Ontario Health Insurance Plan (OHIP)) when you present a valid health card and have the required referral.

Please inquire if you have questions about uninsured services.

Can I book an appointment directly or do I absolutely need a referral?

A referral from your family physician or another medical specialist is required to see Dr. Feilchenfeld. As experts in Internal Medicine and Geriatric Care, Internists and Geriatricians see patients based on specific medical questions posed by the referring doctor. This ensures continuity of care and that the consultation is appropriate for your needs. Please have your doctor forward the referral information.

How does a Geriatrician's role differ?

A Geriatrician is an Internist (or Family Physician) with additional specialized training focused on the unique health needs of older adults (often 65+). They excel at managing 'geriatric syndromes' like falls, frailty, memory loss, and polypharmacy. Dr. Feilchenfeld, with expertise in Internal Medicine and Geriatric Care, applies principles of geriatric care to optimize health, function, and quality of life for older patients. He often takes a very holistic view, considering social and functional aspects alongside medical issues.

Is the focus mainly on diseases or also on daily function?

While diagnosing and managing diseases like Nutritional Assessment & Weight Loss or Investigation of Anemia is crucial, Dr. Feilchenfeld also places significant emphasis on maintaining or improving daily function and quality of life, especially for older adults. The goal is often to help patients remain as independent and active as possible, addressing issues like mobility, self-care, and participation in meaningful activities.

What is the appointment cancellation policy?
