ICD-10 Code C32.9 – Malignant neoplasm of larynx, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C32.9 – Malignant neoplasm of larynx, unspecified
What it is
C32.9 identifies a malignant tumor of the larynx when the exact subsite is not documented. Use it for laryngeal cancer that is confirmed, but not further specified.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include persistent hoarseness, throat discomfort, dysphagia, or a visible laryngeal mass, but you should code only what is confirmed.
When to use this code
Use this code when the provider documents primary laryngeal cancer without naming the exact laryngeal site. It is appropriate for unspecified supraglottic, glottic, or subglottic malignant neoplasm when no more specific code is supported. Check documentation if laterality or subsite is available.
Do not use for
Do not use C32.9 if the record identifies a specific laryngeal subsite, such as glottis or supraglottis. Also avoid it for benign lesions, dysplasia, or metastatic disease to the larynx.
Coding tip
If the pathology or operative note names the exact laryngeal site, code that more specific C32 category instead of the unspecified code.
