Systolic (congestive) heart failure

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • I50.2 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 I50.2 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of I50.2 - other international versions of ICD-10 I50.2 may differ.
Applicable To
  • Heart failure with reduced ejection fraction [HFrEF]
  • Systolic left ventricular heart failure

A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.

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 I50.2. 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.
