Complication of unsp artery following a procedure, NEC, init

This code signifies an adverse event affecting an unspecified artery that occurs as a direct result of a medical procedure. It covers complications such as hemorrhage, thrombosis, or pseudoaneurysm formation in an artery where the specific vessel is not documented. This is for the initial treatment of the complication.

Apply this code when a patient presents with a new arterial complication following a surgical or diagnostic procedure, and the medical record does not specify which artery was affected. Examples include a patient developing a hematoma or pulsatile mass at an unidentifiable arterial access site post-catheterization, or unexplained arterial insufficiency after a general surgical intervention.

• Ensure documentation clearly links the arterial complication to a preceding procedure.
• Only use this code when the specific artery involved is truly unspecified; otherwise, use a more precise code.
• The "A" seventh character indicates an initial encounter for active treatment of the complication.
