2026 ICD-10-CM Diagnosis Code C63.12 – Malignant neoplasm of left spermatic cord
What it is
This code identifies a malignant tumor arising in the left spermatic cord. Use it when the record clearly documents cancer of that specific anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a palpable scrotal or inguinal mass, local swelling, pain, or imaging and pathology confirming malignancy.
When to use this code
Use C63.12 when the provider documents primary cancer of the left spermatic cord, including biopsy or operative reports that specify this location. You should also use it when the final diagnosis names the left spermatic cord as the malignant site. If laterality is not stated, check documentation.
Do not use for
Do not use this code for benign spermatic cord tumors, infection, hernia, or nonspecific scrotal masses. If the cancer site is different or unclear, choose the documented diagnosis instead.
Coding tip
Verify laterality and the exact anatomic site in the pathology or provider note before assigning C63.12.
