Complication of mesent art following a procedure, NEC, init

This code identifies an adverse event affecting the mesenteric artery that occurs as a direct result of a medical or surgical procedure. It covers complications such as injury, thrombosis, or stenosis of the mesenteric artery that are not classified more specifically elsewhere, and it signifies the initial treatment or evaluation of this complication.

Use this code when a patient presents with a newly identified complication of the mesenteric artery, such as an iatrogenic dissection or occlusion, following any type of surgical or interventional procedure. This applies to the initial encounter where the complication is diagnosed and treatment is initiated.

• Requires an external cause code (V00-Y99) to indicate the circumstances of the procedure that led to the complication.
• Do not use for complications of the mesenteric vein; a different code series would apply.
• Ensure the documentation clearly links the mesenteric artery complication to a preceding procedure and specifies it as an initial encounter.
