Do you have insurance? Usually they cover the dermatologist. You might have to schedule it as a skin check though, saying you want him to look for skin cancers on you. Because I am freckled I can always go for that. Without insurance though, you'd have to call around and ask them how much they are going to charge upfront. And you can get that cleared up so I hope you can go.
