Unsp injury of axillary artery, unspecified side, sequela

This code indicates a long-term complication or residual effect stemming from an initial, unspecified injury to the axillary artery. The specific nature of the original injury and the affected side of the body are not documented. This diagnosis signifies that the acute phase of the injury has passed, and the patient is now experiencing ongoing issues directly attributable to that past trauma.

Use this code when documentation clearly states a sequela (e.g., chronic pain, functional impairment, pseudoaneurysm, stenosis) resulting from a previous axillary artery injury, but the initial injury type (e.g., laceration, contusion) and the specific side (left or right) were not specified in the original encounter or are unknown. This code is appropriate for follow-up encounters where the sequela is being treated or evaluated.

• Always attempt to obtain more specific information regarding the original injury type and affected side if possible, as more specific codes exist.
• This code should be used as a secondary diagnosis, following the code for the specific sequela being treated (e.g., I71.2 for pseudoaneurysm).
• Ensure the "S" seventh character is appended for sequela, indicating a complication or condition arising as a direct result of a previous injury.
