We do not accept walk-ins or same day appointments.

Missed Appointment/Cancellation Policy

When an appointment is missed, our first concern is the patient’s safety, well-being and that nothing unfortunate has occurred. However, failure to show up and same day cancellations prevent other patients from being seen. As a result of same day cancellations and no shows, TPMG Coastal Endocrinology will assess the following fees for same day cancellations and no show appointments:

Follow up appointments: $25             

Fees are assessed per occurrence and must be paid at least 48 hours prior to the patient’s next scheduled appointment or that appointment will be cancelled.

After Hours Care

We have an on-call line where patients can reach the provider on call for pressing matters.


If you have questions regarding insurance plans accepted at TPMG Coastal Endocrinology, please contact our office at (757) 963-1488.


Copayments are due at the time of service.


Please allow up to 48 hours for prescription refills.
