Acquired absence of unspecified foot

This code indicates the complete absence of a foot due to an acquired condition, such as trauma, surgery, or disease. It signifies that the patient no longer has a foot, but the specific side (left or right) is not documented or known.

Use this code when documentation clearly states an acquired absence of a foot, but the laterality is unspecified. This is appropriate for cases where a patient has undergone an amputation of a foot, and the medical record does not specify if it was the left or right foot.

• Always attempt to clarify laterality (left or right) with the provider to use a more specific code (Z89.431 or Z89.432).
• This code should be used as a secondary diagnosis to explain the patient's functional limitation or need for a prosthetic.
• Do not use this code for congenital absence of a foot; refer to codes in the Q72 category.
