About C63

C63 is the ICD-10-CM diagnosis code for malignant neoplasm of other and unspecified male genital organs. It belongs to block C60-C63 (malignant neoplasms of male genital organs) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C63.0 (epididymis), C63.1 (cord), C63.2 (scrotum), C63.7 (organs), C63.8 (organs) and C63.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
