Acquired absence of limb, unspecified

This code signifies the complete or partial absence of a limb that was lost after birth due to trauma, surgery, or disease. It indicates a missing extremity that was once present, as opposed to a congenital anomaly.

Apply this code when documentation clearly states an acquired absence of a limb, but the specific limb (e.g., arm, leg) is not identified. This is appropriate for cases where the laterality or specific segment of the missing limb is also unspecified.

• Only use this code when the specific limb affected is not documented.
• Prioritize more specific codes (e.g., Z89.0-Z89.8) if the limb and laterality are known.
• Never use this code for congenital limb deficiencies; refer to codes in the Q71-Q73 range for those conditions.
