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

In ON, medical consultations with specialists like Dr. Green 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. Green. 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 are typical wait times for an appointment?

Wait times for specialist appointments can vary significantly depending on the urgency of the referral, the volume of requests, and Dr. Green's availability. Our office prioritizes referrals based on medical need. We strive to see patients as promptly as possible and will contact you once the referral is processed to schedule an appointment. You can inquire about approximate wait times when booking.

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 Frailty Assessment & Management or Syncope (Fainting) Evaluation), 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 (Nutritional Assessment & Weight Loss). Your family doctor can best determine if a specialist consultation is needed.

What should I bring to my first appointment?

Please bring:

• Your provincial health card (Ontario Health Insurance Plan (OHIP) card).
• The referral letter if you have it.
• A complete list of ALL your current medications (prescriptions, over-the-counter, vitamins, herbs), including doses. Bringing the actual bottles/packaging is often very helpful.
• A list of your past medical history, surgeries, and known allergies.
• Any relevant medical reports, lab results, or imaging (X-ray, CT, MRI) reports you possess.
• A list of your specific questions or concerns for Dr. Green.
