Correct Coding Modifier Indicator (CCMI)
The Correct Coding Modifier Indicator is a flag carried on every National Correct Coding Initiative procedure-to-procedure edit pair, saying whether a modifier may be used to report the two codes together at all. It is the lookup that comes before choosing which modifier to use.
Updated
A Correct Coding Modifier Indicator (CCMI) is a value assigned to each procedure-to-procedure edit in the National Correct Coding Initiative edit files. The edit itself says that two codes are not normally reported together; the indicator says whether that conclusion can ever be overridden by reporting a modifier, or whether it is absolute.
There are three values. An indicator of 0 means that the modifiers associated with these edits cannot be used to bypass the edit — the two codes are not payable together under any circumstance the modifier could describe. An indicator of 1 means those modifiers may be used to bypass the edit where the circumstances genuinely justify it. An indicator of 9 is administrative: it is used where an edit's deletion date is the same as its effective date, so the field carries a value rather than a blank.
In practice
The indicator is the first thing to check when a claim hits a bundling edit, because it decides whether there is a decision to make. Against an edit indicated 0, no modifier opens the line and the question moves to whether the codes were the right ones. Against an edit indicated 1, a modifier may be appropriate — and only then does it matter which one, and whether the record supports it.
Working in that order avoids the most common wasted effort in edit resolution: choosing and documenting a modifier for a pair that was never going to accept one. The indicator lives in the edit file itself and changes as the edits are revised, so it is a lookup against the current file rather than something to memorize alongside a code pair.
Commonly confused with
- Payment policy indicator: A payment policy indicator describes a single code's own payment treatment — its global period, whether a bilateral or multiple-procedure adjustment applies, whether it splits into components. A CCMI describes a pair of codes and whether they may be reported together. One is about a code; the other is about a relationship.
- NCCI PTP edit: The edit is the rule that two codes are not normally reported together. The CCMI is a property of that rule, recording whether it admits an exception. Every edit has one.
- Modifier: A modifier is what a practice reports to claim an exception. The CCMI decides whether the edit will accept one at all. Choosing a modifier before checking the indicator is choosing the answer before knowing whether there is a question.
