Malignant neoplasm of unspecified descended testis

This code signifies a primary cancerous tumor originating in a testis that has descended into the scrotum, but the specific side (left or right) is not documented. It represents a malignant neoplasm of testicular tissue.

Apply this code when the medical record clearly indicates a primary malignant neoplasm of a descended testis, but the laterality is not specified by the provider. This is typically used for initial diagnoses of testicular cancer when further diagnostic workup is pending or when the documentation is incomplete regarding the affected side.

• Avoid using this code if the laterality (left or right testis) is documented; instead, choose the more specific code.
• Always query the provider for clarification on laterality if possible to ensure the highest level of specificity.
• This code is for a primary malignancy; use secondary malignancy codes for metastatic disease to the testis.
