Common questions
FAQs for O’Fallon patients.
What kinds of concerns should I come in for?
If something on your skin is bothering you — persistent, painful, changing, or simply uncertain — it’s reasonable to have it checked. We can evaluate it and guide you on the next steps, whether that’s treatment, monitoring, or reassurance.
What if I’m coming for a second opinion?
Second opinions are welcome. If you have prior records, biopsy results, or photos, bring them along and we’ll incorporate that information into your visit.
How should I prepare for my appointment?
Bring your ID, insurance card (if applicable), a list of your medications, and any relevant history. If you’re concerned about a specific area, note when it started and any changes you’ve observed.
Do you accept insurance?
We accept Medicare and work with many major insurance plans for medical dermatology. Coverage varies, so the best next step is to call — our team can help verify your specific plan details. Cosmetic procedures are typically self-pay.
