Ac emblsm and thombos unsp deep veins of r dist low extrm

This code signifies the sudden blockage of an unspecified deep vein in the right lower leg, below the knee, due to a blood clot. This condition, often referred to as a deep vein thrombosis (DVT), is acute in onset and affects the distal portion of the extremity.

Use this code when documentation clearly indicates an acute DVT in the right distal lower extremity, but the specific deep vein (e.g., anterior tibial, posterior tibial, peroneal) is not identified. Supporting documentation includes physician notes detailing acute symptoms like sudden pain, swelling, and tenderness in the right calf or ankle, along with diagnostic imaging (e.g., ultrasound) confirming a DVT in an unspecified distal deep vein.

• Ensure the documentation specifies "acute" and "distal lower extremity" for accurate coding.
• Do not use this code if a specific deep vein (e.g., popliteal, femoral) is identified; instead, use a more specific code from the I82.4- series.
• Always review for laterality (right vs. left) and acuity (acute vs. chronic) as these are crucial for correct code selection.
