How is payment handled for appointments with Dr. Dhillon? Is it covered by Ontario Health Insurance Plan (OHIP)?

In ON, medical consultations with specialists like Dr. Dhillon 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. You generally do not pay directly for the consultation service itself. Some specific procedures, forms, or administrative tasks might not be covered by Ontario Health Insurance Plan (OHIP) and may incur a separate fee according to provincial guidelines. 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. Dhillon. 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.

What should I do if I have an urgent medical problem?

Dr. Dhillon's office provides specialist consultations and is not equipped for emergency care. If you have an urgent medical issue or emergency, please contact your family doctor, go to the nearest hospital Emergency Department, or call 911.

When should someone be referred to an Internist or Geriatrician?

Referrals are typically appropriate for adults with complex diagnostic challenges, poorly controlled chronic diseases (like advanced Management of Select Rheumatologic Conditions or Investigation of Anemia), multiple interacting medical conditions, or unexplained symptoms. For older adults, referrals are common for geriatric syndromes such as falls, memory decline, frailty, or complex medication management (Chronic Liver Disease). Your family doctor can best determine if a specialist consultation is needed.

What is involved in a Comprehensive Geriatric Assessment (CGA)?

A CGA is a detailed evaluation specifically designed for older adults. It goes beyond standard medical checks to assess multiple domains including: medical conditions, medication review (polypharmacy), functional status (ability to perform daily tasks), mobility and fall risk, cognitive health (memory and thinking), mood (screening for depression/anxiety), nutrition, and social support systems. Dr. Dhillon uses this holistic approach to develop a personalized care plan.
