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

This code signifies a sudden blockage of blood flow in the deep veins of the upper part of the right leg due to a blood clot. This condition, often referred to as deep vein thrombosis (DVT), can lead to pain, swelling, and potentially life-threatening complications if the clot dislodges and travels to the lungs. The "unspecified" nature indicates that the specific deep vein (e.g., femoral, popliteal) is not documented.

Apply this code when documentation clearly indicates an acute DVT affecting the proximal portion of the right lower extremity, and the specific deep vein involved is not identified. This is commonly seen in emergency department visits or initial inpatient admissions for new onset DVT symptoms. Supporting documentation would include imaging reports (e.g., duplex ultrasound) confirming an acute thrombus in an unspecified deep vein of the right proximal lower extremity.

• Ensure the documentation specifies "acute" to differentiate from chronic DVT.
• Verify laterality (right) and anatomical location (proximal lower extremity) are clearly stated.
• If a specific deep vein (e.g., femoral, popliteal) is identified, use a more specific code from the I82.4Y- series.
