Medically necessary consultations, diagnostic tests, and surgical procedures performed by a licensed Otolaryngologist - Head and Neck Surgeon like Dr. Guertin are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when you have a valid referral from your family doctor or another referring physician.

Do I need a referral from my doctor to see Dr. Guertin, an Otolaryngologist - Head and Neck Surgeon?

Yes, for services to be covered by your provincial health plan (Régie de l'assurance maladie du Québec (RAMQ)), a referral from your family physician or another specialist is typically required to see an Otolaryngologist - Head and Neck Surgeon like Dr. Guertin. This ensures coordinated care. Some clinics may offer non-insured consultations without a referral, but this is not standard for provincially covered services. Please check with the clinic or your referring doctor.

How should I prepare for my appointment with an ENT specialist?

For your appointment, please bring your provincial health card, your referral letter (if applicable), a list of your current medications (including over-the-counter drugs, vitamins, and herbal supplements), and any relevant medical records, imaging studies (X-rays, CT scans, MRIs on a disc if possible), or test results you may have (such as previous hearing tests or allergy reports). Be prepared to discuss your symptoms, their duration, and your medical history in detail. It's also helpful to write down any questions you have beforehand.

How are allergies related to ENT problems?

Allergies can significantly impact the ears, nose, and throat. Allergic rhinitis (hay fever) can cause nasal congestion, runny nose, sneezing, post-nasal drip, and itchy, watery eyes. Allergies can also contribute to chronic sinusitis, eustachian tube dysfunction (leading to ear pressure, popping, or fluid), recurrent ear infections, and exacerbate conditions like asthma or voice changes. An ENT specialist may investigate and help manage the ENT-related symptoms of allergies, often by recommending nasal sprays, antihistamines, or discussing options like immunotherapy, sometimes working in conjunction with an allergist.
