How is payment handled for appointments with Dr. Gross? Is it covered by Ontario Health Insurance Plan (OHIP)?
In ON, medical consultations with specialists like Dr. Gross 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. Gross. 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 should I do if I have an urgent medical problem?
Dr. Gross's office provides specialist consultations and is not equipped for emergency care. If you have an urgent medical issue or emergency, please contact your family doctor, go to the nearest hospital Emergency Department, or call 911.
Is Dr. Gross affiliated with a specific hospital?
Hospital privileges can vary. Dr. Gross may have admitting privileges or provide consultation services at Toronto hospitals. This affiliation allows for coordinated care if hospitalization is required. If you are admitted, the hospital team may consult Dr. Gross 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.
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 Chronic Liver Disease or Investigation of Anemia), 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 (Polypharmacy & Medication Optimization). Your family doctor can best determine if a specialist consultation is needed.
What happens after the initial consultation?
After your assessment, Dr. Gross will typically send a detailed consultation report with findings and recommendations to your referring physician. Depending on your specific situation and the reason for referral, Dr. Gross may arrange follow-up appointments, order further tests, or transition care management back to your family doctor with specialist guidance. The plan will be discussed with you.
