Unsp injury of radial art at wrs/hnd lv of unsp arm, sequela

This code signifies a long-term complication or residual effect stemming from an unspecified injury to the radial artery in the wrist or hand region. It indicates that the original injury occurred on an unspecified arm, and the current encounter addresses a condition directly resulting from that past trauma.

Use this code when documenting a patient presenting with a sequela (e.g., chronic pain, diminished blood flow, nerve damage, or functional impairment) that is directly attributable to a previous, unspecified injury of the radial artery at the wrist or hand level. This applies when the specific nature of the initial injury is unknown or not documented, and the affected arm is also not specified.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past radial artery injury at the wrist/hand level.
• Avoid using this code if the specific nature of the initial injury or the affected arm is known; instead, use a more precise sequela code.
