ICD-10 Code C63.10 – Malignant neoplasm of unspecified spermatic cord (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C63.10 – Malignant neoplasm of unspecified spermatic cord
What it is
This code identifies a malignant tumor arising in the spermatic cord when the exact site is not documented. Use it for a confirmed cancer diagnosis involving that structure, but not a more specific subsite.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe a palpable inguinal or scrotal mass, swelling, or pain, with diagnosis confirmed by imaging, pathology, or specialist assessment.
When to use this code
Use C63.10 when the provider documents malignant neoplasm of the spermatic cord and does not specify left, right, or another exact location. It also fits when the chart only states “spermatic cord cancer” without laterality or further detail. If the record identifies a more specific site, code that instead.
Do not use for
Do not use this code for benign spermatic cord masses, inflammatory conditions, or tumors clearly documented elsewhere. Check documentation if the lesion is stated as testicular, scrotal, or inguinal rather than spermatic cord.
Coding tip
Verify laterality and exact anatomic site before assigning C63.10, because a more specific malignant neoplasm code may apply.
