Which ICD-10-CM code represents acquired absence of breast?

• A. Z85.3
• B. Z43.5
• C. Z90.1
• D. Z90.10

Answer: (D)

When coding conditions that describe a patient’s anatomy rather than a disease, use Z codes. An acquired absence of a breast is a permanent loss after surgery and is coded with the designation for acquired absence of breast, specifically the version that indicates the absence is present but the side is unspecified. This directly captures the patient’s current status of lacking a breast. The other options describe different concepts: a history of breast cancer, an encounter for breast reconstruction, or a general or non-breast absence. They don’t reflect the actual condition of having an acquired absence of the breast, which is why the correct code is the one for acquired absence of breast, unspecified side.
