About C62.9
C62.9 is the ICD-10-CM diagnosis code for malignant neoplasm of testis, unspecified whether descended or undescended. It belongs to category C62 (malignant neoplasm of testis), 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 3 subcodes must be used instead.
Within C62, choose C62.9 (unspecified whether descended or undescended) only when documentation doesn't support a more specific option: undescended testis (C62.0) and descended testis (C62.1).
To report this condition, pick the subcode that matches the documentation: C62.90 (undescended), C62.91 (undescended) and C62.92 (undescended).
Use an additional code to identify any functional activity.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
