Moles should be checked regularly for changes to make sure they are not becoming cancerous.  At The Dermatology Center of Newport, we perform total body mole checks and dermoscopy to give you peace of mind that your moles are not harmful.  Some moles may require further evaluation by a minor surgical procedure known as a skin biopsy.  In some cases, the assessment can be made by a non-invasive genetic test known as a pigment lesion assay (Dermtech).

What is DermTech?

DermTech is a non-invasive adhesive biopsy used for suspicious moles.  The adhesive biopsy and Pigmented Lesion Assay (PLA) can help your doctor diagnose melanoma, the most deadly form of skin cancer, without the use of a scalpel.  The PLA uses advanced genetics to identify 2 genes which are abnormal in melanoma skin cancer. DermTech’s PLA can distinguish melanoma from benign pigmented skin lesions such as nevi or moles with a negative predictive value (NPV) of over 99%, sensitivity of 91%, and specificity of 69%, without the need for a surgical biopsy. 

DermTech FAQs

Is DermTech covered by insurance?

While DermTech will submit the laboratory claim to your insurance company on your behalf, there is a chance that it may not be covered. It is best to check with your insurance company prior to treatment. Once your insurance company finalizes your claim, DermTech will send you a bill with any patient responsibility.  DermTech will send an appeal for any denials on your behalf. 

What if I don’t have insurance?

DermTech offers financial assistance to reduce out-of-pocket costs for qualified underinsured patients in the US to no more than $50. Examples of patients who are considered underinsured include: those with high deductible or out-of-pocket expenses and those with non-medical coverage due to a restrictive medical policy. 


Dr. Aszterbaum is amazing! I have had several moles removed by dermatologists and she is my favorite. After I found her, I stopped my search. First, she can stitch from the inside to not leave a scar. Second, she is a perfectionist and is careful when she performs surgery. She doesn't rush you out of the office like dermatologists at Dr. Hutton's. Lastly, she is a beautiful, caring person. I highly recommend Dr. Aszterbaum for any complicated surgery!!!!
