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

Medically necessary consultations with a licensed Dermatologist like Dr. Lomaga, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. 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. Lomaga'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. Lomaga, 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. Lomaga. 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.

How often should I see a Dermatologist like Dr. Lomaga for skin cancer screening?

The recommended frequency for skin cancer screenings by a Dermatologist like Dr. Lomaga varies based on your individual risk factors. These include a personal or family history of skin cancer (especially melanoma), having many moles (e.g., >50) or atypical moles, fair skin that burns easily, a history of excessive sun exposure or tanning bed use, or a suppressed immune system. Your family doctor can assess your risk, or Dr. Lomaga can provide a personalized recommendation after an initial consultation. Regardless of professional check-ups, performing monthly self-skin exams to monitor for any new or changing lesions (using the ABCDEs of melanoma as a guide) is crucial for early detection.

What is the difference between a Dermatologist and an Esthetician?

A Dermatologist, like Dr. Dr. Lomaga, is a medical doctor (MD) who has completed medical school followed by several years of specialized residency training in dermatology. They are qualified to diagnose and treat over 3,000 diseases of the skin, hair, and nails, prescribe medications, perform surgical procedures (like skin cancer removal), and manage complex skin conditions. An Esthetician (or Aesthetician) is a skincare professional trained in cosmetic skin treatments and services that improve the appearance of the skin, such as facials, superficial chemical peels, microdermabrasion, waxing, and makeup application. They are not medical doctors and cannot diagnose skin diseases, prescribe medications, or perform medical or surgical procedures.
