About Z89
Z89 is the ICD-10-CM diagnosis code for acquired absence of limb. It belongs to 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 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z89.0 (finger(s)), Z89.1 (wrist), Z89.2 (wrist), Z89.4 (ankle), Z89.5 (knee), Z89.6 (knee) and Z89.9 (unspecified).
Don't report Z89 together with the conditions in its Excludes1 note: acquired deformities of limbs (M20-M21) and congenital absence of limbs (Q71-Q73).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
