What This Code Means
C32 is the ICD-10-CM diagnosis code for malignant neoplasm of larynx. C32 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering malignant neoplasms of respiratory and intrathoracic organs (c30-c39).
Header codes like C32 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for C32 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
