- How is payment handled for appointments with Dr. Leung? Is it covered by Ontario Health Insurance Plan (OHIP)?
- In ON, medical consultations with specialists like Dr. Leung 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. Leung. 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.
- Is Dr. Leung affiliated with a specific hospital?
- Hospital privileges can vary. Dr. Leung may have admitting privileges or provide consultation services at Toronto hospitals in the area. This affiliation allows for coordinated care if hospitalization is required. If you are admitted, the hospital team may consult Dr. Leung as needed, or he might be involved in your care depending on the specific hospital and service arrangements. Please confirm details with the office if needed.
- Does Dr. Felix Kai-Ying Leung handle prescription refills?
- Generally, ongoing prescription refills should be managed through your family doctor (primary care provider). Dr. Leung will make initial recommendations or adjustments, but routine refills are best handled by your family doctor who manages your overall care, unless specific arrangements are made for certain specialized medications.
