Checked October 2026. Each line below is quoted from the practice's own pages, not written by ClinicCompass. Practices update their sites, so confirm anything that matters to you at your consultation.
Check two things first: whether your insurance plan needs a referral from your primary care doctor, and whether this practice is in your network. Cosmetic visits are paid out of pocket and need no referral. For a cosmetic treatment, ask who will perform it and how often they do it. For a skin check, a changing mole, a rash or anything that is bleeding or not healing, contact the practice directly and say what you have noticed.
