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. Marras. 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.

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 infections or dyslipidemia), 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. Your family doctor can best determine if a specialist consultation is needed.
What exactly does an Internist (Internal Medicine Specialist) do?
An Internist is a medical doctor who specializes in diagnosing, treating, and preventing complex diseases primarily in adults. They are experts in managing conditions affecting multiple organ systems, handling challenging diagnostic puzzles, and coordinating care for patients with multiple chronic illnesses. They often serve as consultants to other physicians.
