Which code indicates an acquired absence of the right upper limb?

• A. Z63.0
• B. Z11.8
• C. Z89.201
• D. Z74.09

Answer: (C)

Understanding how ICD-10-CM codes handle non-disease conditions helps explain this choice. Z codes include codes for acquired absence of a limb, with the decimals specifying which limb and side. For an acquired absence of the right upper limb, the code that precisely communicates both the condition (acquired absence) and the exact limb (right upper limb) is the one chosen. This code cleanly distinguishes it from other limbs or from congenital absence, which would use a different code pattern. The other options don’t describe limb loss at all—one relates to relationship problems, another to a screening encounter, and another to disability-related activity limitations—so they aren’t appropriate for this scenario.
