Q71 vs Z89
Q71 (Reduction defects of upper limb) compared with Z89 (Acquired absence of limb), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Z89 carries an Excludes1 note covering Q71: “congenital absence of limbs (Q71-Q73)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
