Complication of artery following a procedure, NEC, sequela

This code signifies a long-term or residual effect stemming from a complication that occurred in an artery (other than the coronary, cerebral, or peripheral arteries) following a medical procedure. This complication is not further specified elsewhere in the classification and is no longer in its acute phase, but rather represents a permanent or chronic condition resulting from the initial complication.

Apply this code when documenting a patient presenting with a chronic or permanent condition directly attributable to a past procedural complication involving an artery not specifically categorized elsewhere. Examples include persistent arterial stenosis or occlusion, aneurysm formation, or chronic pain due to nerve damage from an arterial injury, where the original complication has resolved but left a lasting impact.

• Ensure the documentation clearly states the complication is a "sequela" or "late effect" of a previous procedural complication.
• Verify the affected artery is not a coronary, cerebral, or peripheral artery, as those have more specific sequela codes.
• Always sequence this code after the code for the specific sequela (e.g., I70.20 for atherosclerosis of native arteries of extremities, unspecified, as a sequela of an arterial complication).
