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

This code signifies a sudden blockage of blood flow in an unspecified deep vein located in the lower part of the left leg, below the knee. This blockage is caused by either an embolus (a traveling clot) or a thrombus (a stationary clot), leading to acute symptoms.

Apply this code when documentation clearly indicates an acute deep vein thrombosis (DVT) or embolism affecting the distal portion of the left lower extremity, but the specific deep vein (e.g., anterior tibial, posterior tibial, peroneal) is not identified. Supporting documentation includes physician notes detailing acute onset symptoms like pain, swelling, and tenderness in the left calf or ankle, coupled with imaging (e.g., ultrasound) confirming DVT in an unspecified distal deep vein.

• Ensure the documentation specifies "acute" and "distal lower extremity" for accurate code assignment.
• Avoid using this code if a more specific deep vein (e.g., popliteal, femoral) is identified; instead, use the appropriate specific code.
• Always query the provider if the laterality (left/right) or the specific deep vein is unclear in the documentation.
