Answer: Report a pulmonary embolism (415.11, Iatrogenic pulmonary embolism and infarction) as the primary diagnosis because the physician was treating that condition with deep venous thrombosis or a blood cot in the leg using 451.11 (Phlebitis and thrombo-phlebitis; femoral vein) or 451.19 ( other) as the underlying condition. Pulmonary embolic disease, similar to thrombo-embolic disease, occurs in the pulmonary system rather than the arterial system and requires codes different from those used to report thrombo-embolic disease, which refers to blood clots in the arterial system.
