Chronic embolism and thombos unsp deep veins of r low extrem

This code signifies the presence of a long-standing blood clot within an unspecified deep vein of the right lower limb. This condition is chronic, meaning it has persisted over time, and the specific deep vein affected (e.g., femoral, popliteal) is not documented.

Apply this code when documentation confirms a chronic deep vein thrombosis (DVT) in the right lower extremity, but the specific deep vein involved is not specified. This is appropriate for patients presenting with ongoing symptoms of DVT where imaging (e.g., ultrasound) confirms a clot but doesn't pinpoint the exact vessel.

• Ensure documentation explicitly states "chronic" and "right lower extremity."
• Avoid this code if a specific deep vein (e.g., femoral, popliteal) is identified; use the more specific code.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
