Puncture wound w/o foreign body of left breast, init encntr

This code signifies a penetrating injury to the left breast caused by a sharp object, such as a needle or a thin piece of wood, where no foreign material remains embedded in the tissue. The wound typically presents as a small, deep opening with minimal tissue disruption.

Apply this code when documenting an initial presentation of a patient with a puncture wound to the left breast, and clinical assessment confirms the absence of any retained foreign body. This is appropriate for injuries like a needle stick or a shallow stab wound without embedded debris.

• Ensure documentation explicitly states "without foreign body" for accurate code assignment.
• Verify the laterality is specifically "left breast" to differentiate from other breast injuries.
• Confirm this is the patient's first encounter for this specific injury; subsequent care would use a different seventh character.
