Acquired absence of other organs

This code signifies the complete or partial absence of an organ or body part that was present at birth but subsequently lost due to disease, trauma, or surgical removal. It applies to situations where the missing organ is not specifically classified elsewhere in the Z90 category.

Use this code for patients who have undergone an amputation of a limb not specified as an acquired absence of a single limb. It is also appropriate for the absence of an internal organ, such as a kidney or spleen, removed due to a medical condition or injury, when a more specific Z90 code is not available.

• Always sequence this code as a secondary diagnosis, following the code for the underlying condition or reason for the organ's absence.
• Ensure the medical record clearly documents the acquired nature of the absence, distinguishing it from congenital absence.
• Avoid using this code if a more specific Z90 code exists for the absent organ (e.g., acquired absence of breast, eye, or limb).
