Laceration with foreign body, left knee, initial encounter

This code signifies a cut or tear of the skin and underlying tissues on the left knee, where a foreign object (e.g., glass, gravel, wood splinter) is embedded within the wound. This is for the initial presentation and active treatment of the injury.

Apply this code when a patient presents to an emergency department or clinic with a fresh laceration on their left knee, and examination confirms the presence of a foreign body requiring removal or further management. This is appropriate for the first encounter for this specific injury.

• Ensure documentation clearly specifies "left knee" and the presence of a foreign body.
• Confirm this is the initial encounter for the injury; subsequent encounters would use a different seventh character.
• Do not use this code if the foreign body is only on the surface of the skin and not embedded within the laceration.
