Fat embolism of pulmonary artery without acute cor pulmonale

This diagnosis code signifies the presence of a fat embolism obstructing a pulmonary artery, specifically when there is no associated acute right-sided heart failure (cor pulmonale). A fat embolism occurs when fat globules enter the bloodstream and travel to the lungs, often following trauma, orthopedic surgery, or pancreatitis.

Use this code when documentation clearly indicates a fat embolism in the pulmonary artery without any mention of acute cor pulmonale. This typically applies to patients presenting with respiratory distress, hypoxemia, or neurological changes after a precipitating event. Supporting documentation would include imaging reports (e.g., CT angiography showing emboli) and clinical notes confirming the absence of acute right heart strain.

• Differentiate from I26.0x codes which specify acute cor pulmonale. The absence of this condition is key.
• Always review the entire medical record for any mention of acute cor pulmonale before assigning this code.
• Consider sequencing this code after the underlying cause of the fat embolism (e.g., fracture, surgery) if applicable.
