Obsessive-compulsive disorder (F42) ICD-10-CM
The F42 code range covers obsessive-compulsive disorder with 6 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
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.
