Partial traumatic amputation of left breast, init encntr

This code signifies a traumatic injury to the left breast resulting in a partial loss of breast tissue. It indicates that the breast has been torn or severed, but not completely detached, due to an external force. This is an acute injury requiring immediate medical attention.

Apply this code for patients presenting with an open wound to the left breast where a portion of the breast tissue has been traumatically removed or is hanging by a flap. This is appropriate for initial treatment of injuries such as those sustained from machinery accidents, animal bites, or other severe lacerations with tissue loss.

• Ensure documentation clearly specifies "partial" amputation and laterality (left breast).
• Always append the appropriate seventh character for the encounter (e.g., A for initial, D for subsequent, S for sequela).
• Code any associated open wounds or other injuries separately if applicable.
