About I26.9
I26.9 is the ICD-10-CM diagnosis code for pulmonary embolism without acute cor pulmonale. It belongs to category I26 (pulmonary embolism), block I26-I28 (pulmonary heart disease and diseases of pulmonary circulation) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.
Within I26, choose I26.9 (without acute cor pulmonale) only when documentation doesn't support a more specific option: with acute cor pulmonale (I26.0).
To report this condition, pick the subcode that matches the documentation: I26.90 (pulmonale), I26.92 (pulmonale), I26.93 (pulmonale), I26.94 (pulmonale), I26.95 (pulmonale), I26.96 (pulmonale) and I26.99 (pulmonale).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
