About C62.0

C62.0 is the ICD-10-CM diagnosis code for malignant neoplasm of undescended testis. It belongs to category C62 (malignant neoplasm of testis), block C60-C63 (malignant neoplasms of male genital organs) and chapter 2 (neoplasms).

To report this condition, pick the subcode that matches the documentation: C62.00 (testis), C62.01 (testis) and C62.02 (testis).

Use an additional code to identify any functional activity.
