Puncture wound without foreign body, left lower leg, sequela

This code signifies a puncture wound to the left lower leg that has healed, but the patient is still experiencing residual effects or complications directly attributable to the original injury. These sequelae could include chronic pain, nerve damage, scar tissue issues, or persistent functional limitations.

Apply this code when documenting a patient encounter for long-term complications or conditions arising from a past puncture wound to the left lower leg, where the initial injury itself has resolved. This is appropriate for follow-up visits addressing chronic issues stemming from the original trauma, not for the initial injury or acute healing phase.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to the previous puncture wound on the left lower leg.
• Verify that the "S" seventh character is appropriate, indicating a sequela, not an active injury or subsequent encounter for routine healing.
