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

This code signifies the presence of a long-standing blood clot within an unspecified deep vein of the right lower leg, below the knee. This condition obstructs blood flow, potentially leading to chronic pain, swelling, and skin changes in the affected extremity. It differentiates from acute events by its prolonged nature.

Apply this code when documentation clearly indicates a chronic deep vein thrombosis (DVT) or embolism affecting the right distal lower extremity, and the specific deep vein involved is not identified. This is appropriate when the physician's assessment confirms chronicity, often based on imaging studies showing organized thrombus or clinical history of symptoms lasting several weeks or months.

• Ensure documentation specifies "chronic" and "unspecified deep veins" of the "right distal lower extremity."
• Do not use for acute DVT; separate codes exist for acute events.
• Avoid using if a specific deep vein (e.g., popliteal, tibial) is documented; more specific codes are available.
