Puncture wound without foreign body, right knee, init encntr

This code signifies a penetrating injury to the right knee caused by a sharp object, where no foreign material remains embedded in the wound. It indicates that the injury is being treated for the first time.

Apply this code for patients presenting with a fresh puncture wound to the right knee, such as from a nail, needle, or thorn, where examination confirms the absence of retained foreign bodies. This is appropriate for the initial visit for this specific injury.

• Ensure documentation explicitly states "right knee" and "puncture wound without foreign body."
• Verify the encounter is the initial treatment for this injury; subsequent encounters will require a different seventh character.
• Do not use if a foreign body is present; instead, select a code that specifies a puncture wound with a foreign body.
