The Missing Piece Solution


Implementing a new behavioral health medical billing system can be overwhelming. Missing Piece leads you through this process and helps you to get started with our ABA billing software for a smooth transition so that your work isn’t disrupted by the change.

Credentialing & Contracting

Our Contracting Team's knowledge and payer relationships establish a strong foundation for your revenue cycle, allowing you to receive maximum reimbursement from your ABA insurance billing.

Eligibility & Benefits

Navigating patient benefits is challenging and time-consuming. With our knowledge of the history of ABA therapy in the United States and expertise in current regulations, we manage this process on your behalf. By ensuring that the correct applied behavior analysis (ABA therapy) billing codes are used, we enable your patients to better understand their benefits and your billing to be accurate.


Most payers require pre-authorization for ABA services. Missing Piece works with payers to obtain ABA authorization for the full recommended and uninterrupted treatment of your patients, in addition to ensuring consistent Revenue Cycle Management.

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.
