Malig neoplasm of left testis, unsp descended or undescended

This code signifies a primary cancerous tumor originating in the left testicle. It indicates malignancy without further specification regarding whether the testis is located in its normal scrotal position or is undescended (cryptorchid).

Apply this code when documentation confirms a malignant neoplasm of the left testis, but the physician's notes do not specify if the testis is descended or undescended. This is appropriate for initial diagnoses or when the laterality is known but the specific testicular position is not yet clarified.

• Do not use this code if the documentation specifies the testis as either descended (C62.0) or undescended (C62.1).
• Always seek clarification from the provider if the documentation is ambiguous regarding testicular descent.
• Sequence this code as the primary diagnosis when the testicular malignancy is the reason for the encounter.
