Unspecified injury of peroneal artery, left leg, sequela

This code signifies a long-term complication or residual effect stemming from an unspecified injury to the peroneal artery in the left leg. This could include chronic pain, impaired circulation, nerve damage, or other persistent issues directly attributable to the original trauma to this specific artery. The nature of the initial injury is not documented or specified.

Use this code when a patient presents with a current condition or symptom that is a direct consequence of a past, unspecified injury to their left peroneal artery. This is appropriate for follow-up encounters where the acute phase of the injury has passed, and the patient is being treated for the lasting effects. It should be applied when the specific type of peroneal artery injury (e.g., laceration, contusion) was never documented or is unknown.

• Always ensure documentation clearly links the current condition to a past peroneal artery injury.
• This "S" seventh character indicates sequela, meaning the residual effect of a previous injury, not the acute injury itself.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code from the S85.2 series.
