Executive Leadership

Deana Sewell, Founder and CEO

Deana started her career running operations in the retail industry. She then moved into banking, where she was hired as a Bank Officer at First National Bank & Trust to manage daily branch operations.

While at First National, Deana helped a friend get financial assistance from insurance for his autistic son. Despite having no experience as a medical billing consultant, she worked through the insurance company’s appeal process, and Deana was able to get the denial for coverage overturned and the child’s therapy covered. Soon after this, she realized that there was a distinct lack of medical billing experts in the industry and a need for ABA therapy billing and insurance services that had the patients’ best interests at heart.

Deana was introduced to other families seeking help navigating the ABA billing insurance process to get coverage for their children’s autism therapy. She developed a passion for helping families fight for insurance coverage for autistic children and eventually left her job to start Missing Piece Billing & Consulting.

Today, Missing Piece is the leader in outsourced billing services for ABA therapy and other behavior health providers across the U.S. Deana is nationally considered an expert in the field of ABA billing and is contacted by ABA providers, consultants and even insurance providers for her opinion on complex billing and reimbursement topics.

Deana, the medical billing experts, and the wider team at Missing Piece continue to fight for families and their children who cannot handle the substantial financial responsibility that comes with raising an autistic child. Just as she played a part in the industry’s history, there’s no doubt that Deana and the team will play a huge role in the future of medical billing in the U.S., too.

What Clients Say..

Like most small businesses, our success is predicated upon personal relationships and a consistent revenue stream.  Since opening, Missing Piece Billing has been a great partner and an essential element of both.  They guided us through the billing and authorization process and took the lead on contracting and patient invoicing, allowing us to focus on serving our families.  As our company has grown from 1 to 100, I can say with great confidence that we would not be where we are today without them.

Missing Piece delivers. Your problems are solved before you even notice, and you benefit from knowledge gained by Missing Piece via other clients’ problems even before they are yours to suffer. They are ahead of the game at every turn, be it denials for improperly reviewed claims, contracting issues, or auth utilization, they have you covered. We could not replace their services with ten full time staffers, and they cost far less than that each month.

Partnering with Missing Piece to handle our insurance and billing needs came at the perfect time for our organization.  Payment and issues with claims consumed a large portion of our week.  Once we started working with the team at Missing Piece, we experienced faster turnaround with payment, billing and authorizations were streamlined, and credentialing couldn’t be easier.  Their dedicated team is always there to support our business and has given us back the time to focus on patient care.

When we began the process to become a Medicaid and insurance provider, a friend advised us to call Missing Piece for help.  As it turns out, that was the best piece of advice we got in relation to this journey.  The folks at Missing Piece have been there every step of the way, providing us with guidance, support, and taking many hours of work onto their workload.  We are so grateful!
