2021 ICD-10-CM Diagnosis Code J09

Influenza due to certain identified influenza viruses

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • J09 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 J09 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of J09 - other international versions of ICD-10 J09 may differ.
Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as J09. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
