ICD-10 Code C63.1 – Malignant neoplasm of spermatic cord (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C63.1 – Malignant neoplasm of spermatic cord
What it is
This code identifies a malignant tumor arising in the spermatic cord, the structure that carries vessels, nerves, and the vas deferens to the testis. Use it when the record clearly documents primary cancer of this site.
Clinical signs
Clinical features may include a palpable scrotal or inguinal mass, swelling, or local pain. Diagnosis is usually confirmed by imaging and pathology; clinical features vary, so refer to documentation.
When to use this code
Use C63.1 when the provider documents primary malignancy of the spermatic cord, including confirmed cancer in this anatomic location. It may also apply when the tumor is described as arising from the spermatic cord or when pathology specifies this site. Check documentation if the record only says “scrotal mass” or “inguinal tumor.”
Do not use for
Do not use this code for benign spermatic cord lesions, inflammatory conditions, or unspecified scrotal disorders. If the cancer is metastatic to the spermatic cord rather than primary there, check documentation.
Coding tip
Code the primary site only when the chart clearly states spermatic cord origin; otherwise, query for clarification.
