Our office hours are 8am-4pm Monday through Thursday and 8am-2pm on Friday. Inquiries regarding insurance benefits received after 12pm may not be processed until the following business day. 

What do I need to file a claim?

To ensure timely submission of insurance claims, please provide the following items for each new patient.

  • Full Name

  • Date of Birth

  • Address

  • Insurance Company Name

  • A Clear Copy of the Patient's Insurance Card (front and back)

How often must I submit my claims?

To allow for a consistent cash flow to the provider, billing must be sent to us on a monthly basis. This allows time to review any claim issues that may occur after submission.

Claims older than two months will incur an additional fee for processing.


What causes claim issues?

The primary reason for rejected claims is that something has changed with the patient's insurance and the provider was not informed. This is why we encourage providers to talk to each patient about their insurance. A quick chat regarding current insurance status can prevent a rejection from happening in the first place.


How do you ensure accurate billing?

Our medical billers are certified biannually. We utilize advanced software and web-based solutions to minimize errors and maximize approval rates.
