Puncture wound without foreign body, unsp knee, sequela

This code indicates a past injury to the knee, specifically a puncture wound that did not involve a foreign body, and the patient is now experiencing a residual effect or complication from that previous wound. The exact knee (left or right) is not specified, and the wound itself has healed, but its lasting impact is being addressed.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained puncture wound to an unspecified knee. This applies to follow-up encounters where the initial injury is no longer acute but has left a chronic issue, such as scarring, nerve damage, or persistent pain.

• Ensure the medical record clearly links the current complaint to a past puncture wound of the knee.
• Confirm there is no foreign body currently present or that was present at the time of the original injury.
• This "S" seventh character indicates a sequela; do not use for the initial treatment of the acute wound.
