  • Edema of lung with heart failure
  • Left heart failure
  • Pulmonary edema with heart disease NOS
  • Pulmonary edema with heart failure
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 I50.1. 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.
