Acute embolism and thrombosis of other specified veins

This code signifies the sudden blockage of a vein, other than those specifically classified elsewhere, by an embolus (a traveling clot) or a thrombus (a stationary clot). It represents an acute vascular event affecting venous structures not covered by more specific ICD-10-CM codes.

Apply this code when documentation specifies an acute venous embolism or thrombosis in a location not otherwise specified, such as a mesenteric vein, splenic vein, or portal vein, and the provider explicitly states "acute." Supporting documentation should clearly identify the affected vein and the acute nature of the event.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Always attempt to find a more specific code if the vein is clearly identified (e.g., I82.3 for cerebral venous thrombosis).
• Do not use for pulmonary embolism (I26.-) or deep vein thrombosis of the lower extremities (I82.4-).
