Are psychiatric consultations and treatments with Ong, a Psychiatrist, covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations, diagnostic assessments, and medication management provided by a licensed Psychiatrist like Ong are generally covered by Medical Services Plan (MSP) in BC 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 Ong's office or Medical Services Plan (MSP).

Do I need a referral to see Ong, 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 Ong 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.

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

The main difference is that a Psychiatrist, like Ong, 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.

What if I experience side effects from medication prescribed by Ong?

It's common for psychotropic medications to have potential side effects, especially when starting a new medication or adjusting a dose. Ong will discuss common side effects to watch for. If you experience side effects, it's very important to communicate this to Ong or his office promptly. Do not stop taking your medication suddenly unless instructed to do so by Ong, as this can sometimes cause withdrawal symptoms or a worsening of your condition. Ong can help manage side effects by adjusting the dosage, switching to a different medication, or suggesting strategies to mitigate them.

How can I prepare for my first appointment with Ong?

For your first psychiatric appointment with Ong, 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 Ong can also ensure you get the most out of your consultation.
