2021 ICD-10-CM Diagnosis Code J91

Pleural effusion in conditions classified elsewhere

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • J91 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2021 edition of ICD-10-CM J91 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of J91 - other international versions of ICD-10 J91 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 (J91) and the excluded code together.
