Pulmonary embolism (I26)

ICD-10 code I26 and its subcategories specifically identify various types of pulmonary embolism, a condition where blood clots or other emboli block blood flow in the lungs. These codes distinguish whether the embolism causes acute cor pulmonale (right heart failure) and describe the embolism's nature, such as septic, saddle, fat, or cement embolism.

The detailed ICD-10 code for pulmonary embolism (I26) includes subdivisions like I26.0 for pulmonary embolism with acute cor pulmonale and I26.9 for cases without it. Codes such as I26.01 and I26.90 cover septic pulmonary embolism, linked to infectious clots in lung arteries. A saddle embolus; a large clot at the artery bifurcation; is coded under I26.02 and I26.92, depending on heart involvement. Other specific codes denote fat embolism or cement embolism types. Using these codes correctly helps identify the exact embolism type and associated heart strain, aiding precise diagnosis and treatment documentation for healthcare providers and coders managing pulmonary vascular emergencies.

Instructional Notations

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

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Pulmonary Embolism

Blocking of the PULMONARY ARTERY or one of its branches by an EMBOLUS.

Pulmonary Infarction

NECROSIS of lung tissue that is cause by the lack of OXYGEN or blood supply. The most common cause of pulmonary infarction is a blood clot in the lung.
