Puncture wound without foreign body, right knee, sequela

This code signifies a past injury to the right knee caused by a sharp object penetrating the skin, but without any retained foreign material. The "sequela" designation indicates that the patient is currently experiencing a residual effect or complication directly attributable to that previous puncture wound, rather than the acute injury itself.

This code is appropriate when documenting a patient presenting with a long-term issue, such as chronic pain, scar tissue complications, nerve damage, or persistent functional limitation, that originated from a puncture wound to the right knee that has since healed. It should be used when the initial acute injury has resolved, and the current encounter addresses these lasting consequences.

• Ensure the medical record clearly links the current symptoms or condition to a previous puncture wound of the right knee.
• Do not use this code for the initial acute injury; instead, use an acute puncture wound code.
• Always code any specific sequela (e.g., chronic pain, scar contracture) in addition to this sequela code.
