Embolism and thrombosis of other arteries

This code signifies the blockage of an artery, other than those specifically classified elsewhere, due to an embolus (a traveling clot or foreign body) or a thrombus (a stationary clot). This arterial occlusion restricts blood flow to the affected tissue or organ, potentially leading to ischemia or infarction.

Use this code when documentation specifies an embolism or thrombosis in an artery not covered by more specific ICD-10-CM codes (e.g., mesenteric, renal, splenic, or other specified arteries). Clinical notes should clearly identify the affected artery and confirm the etiology as either an embolus or thrombus.

• Ensure the documentation specifies an "other" artery; avoid using this code if a more specific arterial site is identified.
• Distinguish between arterial and venous thrombosis/embolism; this code is strictly for arterial involvement.
• Consider an additional code to identify any associated underlying condition or sequelae, such as infarction, if documented.
