Patient Responsibility:

We need our patients to update the office with any insurance, address, pharmacy, or health changes. When you are in for an appointment, please give us your current insurance cards.


Premium Healthcare keeps our cost lower than most Concierge Services by still taking insurance. We ask that all patients keep current insurance plans. Copays, deductibles, and co-insurance still apply to your office visits. Our billing company, Health Sheild, bills out the left over after insurance for us. The billing company number is 302-352-0517 if you have any questions. The Premium is billed in the office. If you send checks directly from your bank account, make sure our address is 1941 Limestone Road Ste 218 Wilmington, DE 19808. You may send all payments to that address, and they will be processed. The billing company uses our group- Delaware Medical Group, LLC (DMG) address.
