Does Cigna healthcare cover removal of a nickel sized, protruding mole on the back?

If an otherwise benign mole, but it is in the way of clothing or irrtated it can be covered by insurance for removal.

Removing a mole on the back may be covered by some insurance companies.  Your insurance company would need to be contacted to find out if it would be a covered procedure or not.  You could try calling yourself or you could be seen in a doctor's office and have them check for you.  

Thanks for your question.  I would check with your insurance company to see what they consider cosmetic and what they consider necessary.  Usually we can remove a mole and send it in for a pathologist to examine, and most insurance companies consider it necessary if a board certified dermatologist deems the removal/biopsy necessary.  Each practice and insurance company can be different, so definitely have a dermatologist check your mole, and do some homework with your insurance company as well.  Best of luck!
