Are psychiatric consultations and treatments with Cusson, a Psychiatrist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations, diagnostic assessments, and medication management provided by a licensed Psychiatrist like Cusson are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when a referral from a family doctor is in place. Coverage for psychotherapy services provided by a psychiatrist can vary; some provinces cover it, while others may have limitations or it may be part of hospital-based programs. Specific medications may also require special authorization or be subject to formulary restrictions. It's crucial to discuss coverage specifics for therapy or any specialized treatments with Cusson's office or Régie de l'assurance maladie du Québec (RAMQ).

Do I need a referral to see Cusson, a Psychiatrist?

Yes, a referral from your family physician or another medical doctor (e.g., a pediatrician for child psychiatry, or an ER physician for urgent assessment) is almost always required to see a Psychiatrist such as Cusson for services covered by the provincial health plan. Mental health conditions often benefit from initial assessment by a primary care provider who can determine the need for specialist psychiatric care. The referral ensures coordinated care, appropriate triaging, and transfer of relevant medical history.

When should someone consider a referral to a Psychiatrist like Cusson?

A referral to a Psychiatrist like Dr. Cusson is typically considered when mental health symptoms are severe, persistent, complex, or not responding adequately to initial treatments provided by a family doctor or therapist. This can include: thoughts of suicide or self-harm; severe depression or mania; psychosis (hallucinations, delusions); debilitating anxiety or panic attacks; complex PTSD; severe OCD; suspected bipolar disorder or schizophrenia; treatment-resistant depression; or when medication management by a specialist is indicated. Psychiatrists are also consulted for diagnostic clarification and comprehensive treatment planning, especially for co-occurring conditions.

How can I prepare for my first appointment with Cusson?

For your first psychiatric appointment with Cusson, it's helpful to gather some information beforehand. Try to make a list of your main concerns, symptoms (including when they started, how often they occur, and their intensity), and any significant life events or stressors. Bring a list of all current medications (psychiatric and non-psychiatric), including dosages, as well as any past psychiatric medications you've tried and your experience with them. Information about your family history of mental health conditions can also be very useful. Be prepared to discuss your personal history, social situation, and coping strategies. Writing down any questions you have for Cusson can also ensure you get the most out of your consultation.

What is the main difference between a Psychiatrist like Cusson and a Psychologist?

The main difference is that a Psychiatrist, like Cusson, is a medical doctor (MD) who has completed medical school and then specialized residency training in psychiatry. Because they are physicians, psychiatrists can diagnose mental health conditions, prescribe and manage psychotropic medications, and provide various forms of psychotherapy. They can also order medical tests to rule out physical causes of psychiatric symptoms. A Psychologist typically has a doctoral degree (PhD or PsyD) in psychology and is trained in psychological assessment, diagnosis, and providing psychotherapy (talk therapy). Psychologists generally cannot prescribe medication in Canada, though they often work closely with psychiatrists or family doctors who do.

How is confidentiality handled in psychiatric care?

Confidentiality is a cornerstone of psychiatric care. Information you share with Dr. Cusson and her team is kept private and protected by law and professional ethics. This means your information will not be disclosed to anyone without your explicit consent, except in very specific situations where there is a legal obligation or an immediate risk of serious harm to yourself or others (e.g., imminent risk of suicide or homicide, child abuse, or a court order). Dr. Cusson will typically discuss the limits of confidentiality with you at the beginning of your treatment.
