In addition to numerous code changes in the ICD-10-CM code set, there are 22 Excludes1 notes that will be changing to Excludes2 notes. The Cooperating Parties* had issued interim guidance in October, 2015 acknowledging that some modifications were required to the Excludes1 notes within the system.
First, a couple definitions from the ICD-10-CM Official Guidelines for Coding and Reporting FY 2017.
“A type 1 Excludes note is a pure excludes note. It means “NOT CODED HERE!” An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.”
“A type 2 Excludes note represents “Not included here.” An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.”
For FY2018, a significant attempt has been made to determine if an Excludes1 note is always appropriate in the current location, resulting in these 22 changes. Many of the Excludes1 note changes for FY2018 not only change these to an Excludes2 note, but also change the location of the Excludes2 to more specific code locations within the category. These changes will now provide specific guidance on additional code assignment to only some codes within the category, rather than the entire category.
This is a significant and truly beneficial effort on the part of CMS and the Cooperating Parties*. I encourage you to explore these changes and understand their implications.
