About Us

We are Gateway Billing.

Gateway Billing Services was founded by a physician for physicians.

Every day, physicians depend immensely upon the proper billing and coding of services in order to earn the reimbursement to which they are entitled. Yet, every day, physicians around the nation lose money that is owed to them because their internal billing staff, or third party billing company, is not performing at the level required.

As lesser in-house billing staff or third party billing companies make errors, those errors are compounded by following incorrect billing practices and guidelines.

That’s exactly why Gateway Billing Services was founded. The physicians we serve today are pleased in knowing that they are in good hands – the care of expert revenue cycle professionals who understand the nuances and complexity of specialty coding, proper claim submission, and treatment of clearinghouse errors.

Gateway Billing Services places particular emphasis and focus on claim rejections. We understand that many claims may be rejected inappropriately, and that others may not receive any response at all. We monitor all such claims with the level of care that physicians expect and deserve.

Significant resources have been deployed at Gateway Billing Services, including necessary financial, accounting and legal expertise, combined with professionals that represent the best of revenue cycle and medical billing.

Serving physicians for more than seven years, Gateway Billing Services is ready to help you.

Meet the team.
