- How is payment handled for appointments with Dr. Lu? Is it covered by Ontario Health Insurance Plan (OHIP)?
- In ON, medical consultations with specialists like Dr. Lu 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. Lu. 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.
- How long should I expect my appointment to last?
- Initial consultations with Dr. Lu are comprehensive and typically require more time, often ranging from 45 to 75 minutes, depending on the complexity of your medical history and concerns. Follow-up appointments are usually shorter. We recommend allowing ample time for your visit, including check-in and potential waiting periods.
- What is the appointment cancellation policy?
- We understand that unforeseen circumstances arise. If you need to cancel or reschedule your appointment, please provide at least 24-48 hours notice so we can offer the time slot to another patient waiting for consultation. Failure to provide sufficient notice may result in a missed appointment fee (if applicable per clinic policy). Please contact the office directly to make changes.
- Can a family member or friend accompany me to the appointment?
- Yes, absolutely. Patients are welcome to bring a family member, friend, or caregiver to their appointment for support, to help recall information, or to ask questions. Especially for complex discussions or if memory is a concern, having a second person present can be very beneficial.
- 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 urinary incontinence or frailty), 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 (Perioperative Medical Optimization). Your family doctor can best determine if a specialist consultation is needed.
