CMS Clarifies the Proper Use of Modifier 59

The Centers for Medicare and Medicaid Services (CMS) has clarified the proper use of modifier 59 in a special Jan. 3 edition of MLN Matters®. The article describes existing policy and provides descriptors and examples of when to use modifier 59 and the X modifiers.

According to the CPT Manual, Modifier 59 identifies procedures or services, other than evaluation and management (E/M) services, that are not normally reported together but are appropriate under certain circumstances.
