Oth injury of brachial artery, left side, sequela

This code signifies a long-term complication or residual effect stemming from a previously sustained injury to the brachial artery in the left arm. These sequelae can include chronic pain, nerve damage, impaired circulation, or functional limitations that persist after the initial injury has healed.

Apply this code when documenting a patient presenting with a current condition directly attributable to an old, healed injury of the left brachial artery. This is appropriate for follow-up encounters addressing the lasting consequences, rather than the acute injury itself.

• Requires a seventh character "S" to indicate sequela, meaning the patient is seen for the residual effects of a past injury.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, nerve palsy).
• Ensure documentation clearly links the current condition to a previous left brachial artery injury.
