Z89.4Acquired absence of toe(s), foot, and ankle

Z89.4 is the ICD-10-CM diagnosis code for acquired absence of toe(s), foot, and ankle. It belongs to category Z89 (acquired absence of limb), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within Z89 (acquired absence of limb), Z89.4 is specifically for acquired absence of toe(s), foot, and ankle. Related codes cover thumb and other finger(s) (Z89.0), hand and wrist (Z89.1), upper limb above wrist (Z89.2), leg below knee (Z89.5), leg above knee (Z89.6) and unspecified (Z89.9).

To report this condition, pick the subcode that matches the documentation: Z89.41 (toe), Z89.42 (toe(s)), Z89.43 (foot) and Z89.44 (ankle).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
