ICD-10 Code C62.90 – Malignant neoplasm of unspecified testis, unspecified whether descended or undescended (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C62.90 – Malignant neoplasm of unspecified testis, unspecified whether descended or undescended
What it is
C62.90 identifies a malignant tumor in a testis when the side is not specified. Use it when the record confirms testicular cancer but does not state whether the testis is descended or undescended.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include a painless testicular mass, enlargement, or firmness, but the diagnosis should be supported by the provider’s assessment and pathology.
When to use this code
Use this code when documentation states malignant neoplasm of the testis without laterality or descent status. It also fits when the chart confirms testicular cancer but does not identify a more specific testicular site. Check documentation if another testis code is documented elsewhere.
Do not use for
Do not use this code for benign testicular lesions, unspecified scrotal masses, or cancers clearly documented as another male genital site. If the testis is specified as descended or undescended, choose the more specific code.
Coding tip
Before finalizing, verify whether the note specifies descended or undescended testis, because that detail can change the code selection.
