Why MAS?

Billing & Coding

Two of the greatest causes of financial loss for a practice are poor documentation and poor accounts receivable follow-up.
Documentation guidelines have become more complicated. Poor documentation can result in denials, undercoding, and audit penalties. This translates to lost revenue.

Accounts receivable follow-up is important if a medical practice is to maximize income

Customer service makes the difference. Today's patient wants clear and concise answers to their billing questions.
In this world of ever-changing standards, an efficient billing department is a necessity if you want to remain competitive in the medical environment.
