Other specified injury of left renal artery, sequela

This code signifies a long-term complication or late effect resulting from a previously sustained, specific injury to the left renal artery, excluding those classified as lacerations or punctures. These sequelae can include chronic conditions such as renal artery stenosis, aneurysm formation, or persistent arteriovenous fistula, directly attributable to the initial trauma.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of an old, specified injury to their left renal artery. This applies when the acute phase of the original injury has passed, and the current clinical problem is a residual effect. Examples include follow-up for chronic hypertension due to post-traumatic renal artery stenosis.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., I70.1 for renal artery atherosclerosis).
• Ensure documentation clearly links the current condition to a past, specified left renal artery injury.
• Verify that the original injury was not a laceration or puncture, as those have different sequela codes.
