Pulmonary embolism (I26) ICD-10-CM
The I26 code range covers pulmonary embolism with 15 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- pulmonary (acute) (artery)(vein) infarction
- pulmonary (acute) (artery)(vein) thromboembolism
- pulmonary (acute) (artery)(vein) thrombosis
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- cor pulmonale without embolism I27.81
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the I26 range.
Pulmonary Embolism
Blocking of the PULMONARY ARTERY or one of its branches by an EMBOLUS.
About the I26 Code Range
A pulmonary embolism occurs when an embolus blocks the pulmonary artery or one of its branches.
The codes first separate embolisms with acute cor pulmonale, under I26.0, from those without it, under I26.9. Both branches distinguish septic, saddle, cement, fat, and other embolisms. The branch without acute cor pulmonale also separates single from multiple subsegmental thrombotic embolisms.
