Acute embolism and thrombosis of right iliac vein

This diagnosis code signifies the sudden blockage of the right iliac vein by an embolus (a traveling clot) or a thrombus (a stationary clot). This condition restricts blood flow from the right lower extremity, potentially leading to swelling, pain, and other complications.

Apply this code when documentation explicitly states an acute thrombotic or embolic event affecting the right iliac vein. This is typically supported by imaging studies such as ultrasound, CT venography, or MRI, along with clinical signs and symptoms consistent with acute deep vein thrombosis (DVT) in the specified location.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Distinguish between acute and chronic conditions; this code is for acute presentations only.
• Verify if the embolism or thrombosis is spontaneous or secondary to another condition, as this may impact additional coding.
