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

In ON, medical consultations with specialists like Dr. Leitch 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. Leitch. 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.

Why is reviewing multiple medications (polypharmacy) important?

As people age or develop multiple health conditions, they often take many medications. Polypharmacy increases the risk of side effects, drug interactions, falls, confusion, and non-adherence. A careful review helps ensure each medication is truly necessary, effective, and safe, potentially leading to deprescribing (stopping unnecessary drugs) and simplifying the regimen.

What typically happens during a first consultation?

During your initial visit, Dr. Leitch will conduct a thorough review of your medical history, symptoms, and medications based on your referral and the information you provide. He will likely perform a relevant physical examination. Following this assessment, he will discuss his findings, potential diagnoses, recommended further investigations (if any), and a proposed management plan. There will be time for you to ask questions.
