Frequently Asked Questions (FAQs)

What is a FHO in Ontario2019-12-06T14:13:18-05:00

A Family Health Organization (FHO) is an initiative of the Ontario Medical Association and the Ontario Ministry of Health and Long-Term Care. An FHO is a group of family physicians who are working together to give you and your family better access to quality primary health care services.

Can I go to another walk-in clinics if I am part of your FHO?2019-11-13T13:00:18-05:00
The preference is that you DO NOT go to another walk-in clinic outside of uMedical.
If you belong to uMedical FHO, your doctor will be billed by OHIP if you visit a different clinic.
Additionally, if you go to a different walk-in clinic, that clinic DOES NOT FORWARD YOUR RECORDS to uMedical, so our records of your health will not be complete.
The government compensates uMedical for remaining open extra hours and into the evening many times per week to ensure you have access to urgent medical care.
What services are not covered by OHIP for patients that are part of a FHO?2019-11-13T13:01:34-05:00
The Ontario Health Insurance Plan (OHIP) pays for most of your medical visits to our office.
There are, however, uninsured services, which OHIP does NOT COVER, such as:
  • prescription refills by phone
  • medical forms for insurance
  • legal or employment purposes
  • photocopying, faxing and transferring medical records
While you can pay for these services on an as-needed basis, Family Physicians at uMedical Station offer a Block fee program ( link) as a more convenient and cost-effective way to manage these charges.
Please speak to a receptionist to enquire about this plan.

I recently did a blood test but I haven’t heard from my doctor yet?2022-11-20T14:18:03-05:00

Your family doctor receives blood work and diagnostic imaging reports within a week. MRI’s/ CT Scans/ Mammograms within 2 weeks.  Some doctors will ask you to book a visit a few weeks after you have done your tests, others will say that you will be called only if you have an abnormal result. Others will book a follow-up appointment a few months after your first visit for both follow-up and results review. This plan should be discussed with your doctor during your visit. If you want to have a discussion with your doctor about your results, please let us know and your physician will decide how the results are relayed to you. It could be a simple message from them or it could be an appointment for discussion. For any abnormal results, your physician will always communicate with you to let you know and discuss results directly with you. We ask patients to avoid multiple calls for results relaying.
