ICD-10 Code C75.2 – Malignant neoplasm of craniopharyngeal duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C75.2 – Malignant neoplasm of craniopharyngeal duct
What it is
C75.2 identifies a malignant tumor arising from the craniopharyngeal duct region. Use it for documented cancer in this anatomic area when the record specifies this site.
Clinical signs
Clinical features vary; refer to documentation. Patients may present with signs related to a mass in the sellar or suprasellar region, but coding should follow the confirmed diagnosis, not symptoms alone.
When to use this code
Use C75.2 when the provider documents a malignant neoplasm of the craniopharyngeal duct or clearly identifies that exact site as the primary cancer location. It is appropriate for confirmed malignancy in this region, including pathology or imaging-supported documentation. If the site is described differently, check documentation before assigning this code.
Do not use for
Do not use this code for benign craniopharyngeal lesions, uncertain masses, or symptoms without a confirmed malignant diagnosis. If the record names another primary site, code that site instead.
Coding tip
Verify the exact anatomic site and confirm malignancy before assigning C75.2; if the wording is unclear, check documentation.
