Modifier 25 and 59

Often it is very tempting for billing personnel to append a Modifier 25 or 59 to override or bypass the CCI edit process this is a common misuse of the 25 and 59 modifiers as this is not always the appropriate solution. It is important for billing personnel to understand that a modifier is used to modify a procedure or service but is not intended to change the definition of the CPT code.

Appending a Modifier 25 or 59 to bypass edits can be risky business potentially causing an audit for noncompliance. Because of this, it is imperative to understand both your federal and local guidelines when appending modifiers to claims based on your individual state and payer guidelines.
