  • The 2021 edition of ICD-10-CM F45 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of F45 - other international versions of ICD-10 F45 may differ.
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (F45) and the excluded code together.
