- This is the American ICD-10-CM version of I50.1 - other international versions of ICD-10 I50.1 may differ.

- Left heart failure
- Pulmonary edema with heart disease NOS
- Pulmonary edema with heart failure
Type 1 ExcludesType 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 I50.1. 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.
