A Note About Insurance

As discussed in her Office Policy, Dr. McCarthy does not process insurance claims. Nonetheless, This information will expedite the processing of prior authorization requests for medications, so please complete that section.

A Note About Messaging

Please note that messaging within the portal is not available. Instead, please contact Dr. McCarthy as follows:


  • Portal issues:

  • Billing issues:

  • All other issues: until the transition is fully complete, patients should call Dr. McCarthy directly at her office number (703-288-3535). This includes issues like scheduling, school forms, letters for college, and, as always, ALL medical clinical matters.


Notes About the Credit Card Billing System


  • To ensure continuity of treatment, activate your portal as soon as possible. Dr. McCarthy is already using this new billing system and your credit card is required to charge fees directly to your credit card at the time of service. Your active portal is also required for Dr. McCarthy to submit prescriptions.

  • To complete the transition to the new system, your outstanding balance from the old system must be cleared (note: these balances must still be paid the old-fashioned way, by check). As part of the initial portal set-up, we will send a statement for your outstanding balance to your portal rather than mailing a physical statement. Additionally, to simplify things just this once, although email is not secure like the portal, the billing administrator can also send your balance information via email if you prefer. Just send your request to

  • Please note: Dr. McCarthy recognizes that the old billing system causes the accrual of outstanding balances through no fault of the patient. Thus, even as the new credit card billing system becomes active, you may receive a statement for past visits under the old system. Please understand that this dual billing situation is only temporary, pending clearance of your outstanding balance.



Thank you again, and don’t hesitate to reach out with any questions!
