ICD-10 Code C76.3 – Malignant neoplasm of pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C76.3 – Malignant neoplasm of pelvis
What it is
C76.3 identifies a malignant neoplasm located in the pelvis when the exact primary site is not specified. Use it for cancer documented as arising in pelvic soft tissues or structures without a more precise anatomic code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe a pelvic mass, pain, pressure, or symptoms from local invasion, but you should code only what is documented and confirmed as malignant.
When to use this code
Use C76.3 when the provider documents a malignant tumor of the pelvis and the chart does not identify a more specific primary site. It is also appropriate when pathology or imaging supports malignancy, but the exact origin remains unspecified. Check documentation if the lesion could be coded to a more specific site.
Do not use for
Do not use this code for benign pelvic masses, metastatic disease to the pelvis, or cancers with a clearly documented primary site elsewhere. If the neoplasm is secondary or more specifically located, choose the correct code instead.
Coding tip
Always review the pathology, operative note, and imaging report before assigning C76.3.
