Patient Info

Insurance and Billing

Dr. Parnell participates with Medicare and accepts Medicare fees.  If Medicare is your primary insurance, we will submit claims directly to them on your behalf.  Billing of any supplemental insurance claims is the responsibility of the patient, but Medicare will forward claims to your secondary if prior arrangements have been made.

 We are in-network providers for both Aetna and Cigna PPO insurance plans.

We are “out-of-network” providers for all other private health insurance companies. We will gladly provide you a copy of your itemized, coded bill that you can submit to your insurance company for out-of-network reimbursement.


If you have a high deductible, insurance often does not kick in to cover routine physician visits. Healthy patients with a high deductible often end up paying out of pocket for dermatology visits, regardless of whether their doctor is in-network or not. Therefore, you may choose to see the dermatologist of your preference. Additionally, you can use your health savings account (HSA) card to pay for your medical visit at our office.


Payment is due at the time of service for non-insurance-contracted patients. Please note that cosmetic procedures are generally not covered by any insurance carriers.


For your convenience, our medical history form is linked below if you would like to fill it out and bring it to your first appointment. We have also provided a copy of our HIPPA notice of privacy practices both in English and Spanish. This is provided for your review and to inform you how we comply with the privacy of your medical information.
