Which code represents absence of the right eye?

• A. Z90.01
• B. Z90.02
• C. Z85.01
• D. Z99.89

Answer: (A)

The concept being tested is how ICD-10-CM codes capture absence of a body part. When a body part is absent, the Z90.0x block is used to indicate an acquired absence, and the final digits specify the part and the side. For the right eye, the code with .01 is used, so Z90.01 precisely communicates an acquired absence of the right eye. The other options don’t describe absence of the right eye: Z90.02 would indicate acquired absence of the left eye; Z85.01 relates to a personal history of malignant neoplasm of the eye; Z99.89 doesn’t pertain to absence of a body part.
