Saddle embolus of pulmonary artery w/o acute cor pulmonale

This code signifies a large blood clot (embolus) lodged at the bifurcation of the main pulmonary artery, resembling a saddle, without evidence of acute right heart failure. This type of pulmonary embolism obstructs blood flow to both lungs, leading to significant hemodynamic compromise.

Apply this code when documentation clearly states "saddle embolus of pulmonary artery" and explicitly denies the presence of acute cor pulmonale. This diagnosis is typically made via imaging studies such as CT pulmonary angiography (CTPA).

• Ensure documentation specifically excludes acute cor pulmonale; otherwise, a different code may be more appropriate.
• Do not confuse with other types of pulmonary emboli (e.g., peripheral, massive) that are not specifically described as saddle emboli.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter.
