Sing subsegmental throm pulm emblsm w/o acute cor pulmonale

This code signifies a blood clot obstructing a single, small pulmonary artery branch, specifically a subsegmental vessel, without causing immediate right-sided heart strain. It indicates a localized embolic event within the lung vasculature.

Apply this code when documentation clearly states a subsegmental pulmonary embolism (PE) and explicitly denies acute cor pulmonale. This is typically diagnosed via CT pulmonary angiography (CTPA) showing a clot in a subsegmental artery.

• Ensure documentation specifies "subsegmental" and explicitly rules out acute cor pulmonale.
• Do not use if the PE is in a larger vessel (e.g., lobar, segmental) or if acute cor pulmonale is present.
• Consider sequencing with codes for underlying conditions contributing to the PE, such as deep vein thrombosis (DVT).
