ICD-10 Code C32.3 – Malignant neoplasm of laryngeal cartilage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C32.3 – Malignant neoplasm of laryngeal cartilage
What it is
This code identifies a malignant tumor arising in the cartilage of the larynx. Use it when documentation specifies cancer of laryngeal cartilage rather than a broader laryngeal site.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include hoarseness, throat discomfort, dysphagia, or a visible laryngeal mass confirmed by examination or imaging.
When to use this code
Use C32.3 when the provider documents primary malignant neoplasm of laryngeal cartilage. It also fits pathology, imaging, or operative reports that clearly localize the malignancy to laryngeal cartilage. If the site is described only as laryngeal cancer, check documentation for a more specific location.
Do not use for
Do not use this code for benign laryngeal lesions, metastatic disease to the larynx, or cancers of other laryngeal subsites. If the record does not specify cartilage involvement, check documentation.
Coding tip
Code to the most specific laryngeal site documented; cartilage involvement must be explicit.
