Congenital absence of unspecified limb(s)

This code signifies the complete congenital absence of one or more limbs, where the specific limb(s) affected are not documented. This is a birth defect characterized by the failure of a limb or limbs to develop during gestation.

Apply this code when medical records clearly state the congenital absence of a limb but do not specify whether it's an upper or lower extremity, or which side. Documentation supporting its use would include genetic reports, neonatology notes, or imaging studies confirming aplasia without further anatomical detail.

• Only use this code when the specific limb is truly unspecified in the documentation.
• Avoid using this code if the documentation specifies an upper limb (e.g., Q71.-) or lower limb (e.g., Q72.-).
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, such as for initial evaluation or prosthetic fitting.
