Are consultations and dermatological treatments with Dr. Rosen, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. Rosen's office or Ontario Health Insurance Plan (OHIP) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. Rosen, a Dermatologist?

Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. Rosen. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.

If Dr. Rosen recommends phototherapy, what does that involve?

Phototherapy, also known as light therapy, is a medical treatment where your skin is exposed to specific wavelengths of ultraviolet (UV) light under strict medical supervision. Dr. Rosen might recommend it for conditions like psoriasis, eczema, vitiligo, or cutaneous T-cell lymphoma. Treatments are typically given 2-3 times a week in a specialized light cabinet or with a handheld device for smaller areas. The type of UV light (e.g., Narrowband UVB, PUVA) and treatment duration are carefully controlled. It works by reducing inflammation and slowing down the rapid growth of skin cells. You'll be given specific instructions, including eye protection.

When should someone consider seeing a Dermatologist like Dr. Rosen?

A referral to a Dermatologist like Dr. Rosen is often recommended by a family physician for: any new or changing moles or skin growths; persistent or severe skin rashes (e.g., eczema, psoriasis) not responding to initial treatments; severe or cystic acne; chronic hives; significant hair loss or scalp disorders; problematic nail conditions (e.g., persistent fungal infections, unusual changes); suspected skin infections; or for expert skin cancer screening, especially if you have risk factors like a personal or family history of skin cancer, numerous moles, or significant sun exposure. Early consultation can be key for effective management and diagnosis.

What kind of sunscreen does Dr. Rosen recommend?

While specific brand recommendations can vary, Dr. Rosen would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. Rosen can provide personalized recommendations based on your skin type and lifestyle during your consultation.
