ICD-10 Code C62.02 – Malignant neoplasm of undescended left testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62.02 – Malignant neoplasm of undescended left testis
What it is
This code identifies a malignant tumor arising in the left testis when that testis remains undescended. It is used for cancer documented specifically in an undescended left testicle.
Clinical signs
Findings may include a painless testicular or inguinal mass, enlargement, or a nonpalpable testis with imaging or operative confirmation of malignancy. Clinical features vary; refer to documentation.
When to use this code
Use C62.02 when the record clearly states malignant neoplasm of the undescended left testis. This applies whether the diagnosis is made by pathology, imaging, or operative findings, as long as the left side and undescended status are documented. If the side or location is unclear, check documentation.
Do not use for
Do not use this code for benign testicular disease, unspecified testicular cancer, or malignancy of a normally descended testis. If the documentation does not specify the left undescended testis, check documentation.
Coding tip
Confirm both laterality and undescended status in the note before assigning C62.02.
