Acute embolism and thrombosis of right calf muscular vein

This code signifies a sudden blockage of blood flow within a muscle vein in the right calf, caused by either an embolus (a traveling clot) or a thrombus (a stationary clot). This acute event leads to impaired venous drainage from the affected muscle.

Apply this code when documentation specifies an acute venous occlusion, such as deep vein thrombosis (DVT) or an embolism, located specifically within a muscular vein of the right calf. Supporting documentation should clearly indicate the acute nature and the precise anatomical location.

• Differentiate from I82.462 (left calf) and I82.469 (unspecified calf) based on laterality.
• Ensure the documentation specifies "muscular vein" to avoid using codes for other deep veins (e.g., popliteal, tibial).
• Confirm the acute nature of the event; chronic conditions would use different codes.
