- How is payment handled for appointments with Dr. MacLean? Is it covered by Ontario Health Insurance Plan (OHIP)?
- In ON, medical consultations with specialists like Dr. MacLean 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. MacLean. 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.
- Is Dr. MacLean affiliated with a specific hospital?
- Hospital privileges can vary. Dr. MacLean may have admitting privileges or provide consultation services at Winchester's local hospitals or other designated facilities. This affiliation allows for coordinated care if hospitalization is required. If you are admitted, the hospital team may consult Dr. MacLean as needed, or she might be involved in your care depending on the specific hospital and service arrangements. Please confirm details with the office if needed.
- 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.
- Will Dr. MacLean replace my family doctor?
- No, Dr. MacLean acts as a specialist consultant. Your family doctor (or primary care provider) remains responsible for your routine healthcare, ongoing prescriptions (unless specified otherwise by the specialist), and coordinating your overall care. Dr. MacLean will communicate findings and recommendations back to your family doctor.
- How does Dr. MacLean communicate with my family doctor?
- Clear communication with your referring physician is a priority. Dr. MacLean will send a comprehensive consultation letter outlining the assessment findings, diagnosis (if established), and treatment recommendations. This ensures your family doctor is fully informed and can continue to coordinate your overall care effectively.
