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. Mak. 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 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. Mak uses this holistic approach to develop a personalized care plan.
- 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. Mak'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.

- What typically happens during a first consultation?
- During your initial visit, Dr. Mak will conduct a thorough review of your medical history, symptoms, and medications based on your referral and the information you provide. She will likely perform a relevant physical examination. Following this assessment, she will discuss her findings, potential diagnoses, recommended further investigations (if any), and a proposed management plan. There will be time for you to ask questions.
