Billing & Insurance Get the Facts

If you do not have health insurance coverage, you are still welcome as a patient of ours. You will be considered “Private Pay” with our practice. Effective July 15, 2020, we now kindly require a credit card to be on file with our office so that your payment can be automatically drafted the day of or after your appointment. If you decline to place a credit card on file, you may pre-pay your visit in full prior to the appointment date. Please call our billing office to receive your estimate for services at (512)458-8400, option 6. For more detailed information click here

Payment Card Industry (PCI) Security Standards Council offers robust and comprehensive standards to enhance payment card data security and reduce exposure to credit card fraud. PCI Data Security Standard (DSS) provides an actionable framework for developing a robust payment card data security process, including prevention, detection, and appropriate reaction to security incidents. 

Phreesia’s secure PCI-DSS compliant system never stores sensitive credit card information in our office system or Phreesia’s, it is stored with the merchant.

We prefer that you enter your credit card information while confirming/pre-registering for your appointment through our secure platform, Phreesia. Please pay close attention to your appointment reminders sent via text & email to complete pre-registration. You can also deliver your credit card information over the phone, by mail, or in person, but the most secure way is online during pre-registration. 

We accept most major insurance plans, including Medicare. Please contact your insurance to verify that Texas Diabetes & Endocrinology is a contracted provider.

We will be happy to provide you with any procedure codes that are to be billed so that you may confirm with your insurance plan that it is covered

If your copay is not listed on your insurance card, please contact the 1-800 number on the back of your card to check your benefits.

Due to the lack of Endocrinologists in the Austin & surrounding areas, we do require a referral from your PCP in order to be seen as a new patient with Texas Diabetes & Endocrinology. Once we receive your referral electronically or via fax, a scheduler will be in contact to schedule your appointment. 

Of note: If your insurance requires a referral to see a specialist, you will need to have your referral processed before seeing a specialist. Please contact your insurance carrier to confirm if your plan requires you to obtain a referral to see a specialist. To learn more about our referral process, select the following link: Referrals

If you are an existing patient & need an extension of time or visits added to the current authorization, please contact your PCP’s office at least one week in advance of when you need the authorization. We cannot guarantee they can backdate the referral.

Please schedule an appointment with your provider to discuss if this is something we will consider filling out.

Our office utilizes an automated system to remind you of your appointment three days in advance as a courtesy. This system allows you to confirm or cancel your appointment. If you need to cancel or reschedule your appointment please call at least 24 hours in advance. This allows us to make your appointment time available to other patients who need an earlier appointment. Appointments cancelled with less than 24 hours notice will be charged a late cancellation fee of $50.

Our office understands that emergencies arise and appointments cannot always be kept. Your appointment time is reserved with your provider in advance. We do not double book patients so we ask that you give as much notice as possible if you are not going to be able to keep your scheduled appointment. This allows us to fill the appointment with another patient that needs to be seen. No shows will be charged a fee of $50.
