Puncture wound w/o foreign body of left upper arm, init

This code signifies a penetrating injury to the left upper arm caused by a sharp object, such as a needle, nail, or thorn, that does not leave any foreign material embedded in the tissue. The wound is characterized by a small entry point and may involve varying depths of tissue damage without the presence of an object within the wound itself.

Apply this code when documenting the initial treatment for a patient presenting with a puncture wound to their left upper arm where no foreign body is identified or removed. This includes injuries sustained from stepping on a sharp object or being pricked by a tool, as long as the object did not break off and remain in the wound.

• Ensure documentation explicitly states "without foreign body" for accurate code selection.
• Verify the encounter is the initial treatment for this specific injury; subsequent care would require a different encounter character.
• Confirm the injury location is precisely the left upper arm, as laterality and anatomical site are crucial for specificity.
