- 012Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CCsurgical
- 013Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCCsurgical

- malignant neoplasm of aryepiglottic fold or interarytenoid fold, marginal zone (C13.1)
- malignant neoplasm of aryepiglottic fold or interarytenoid fold NOS (C13.1)

Excludes1 — never code together — inherited from C30-C39
The conditions below can never be reported together with C32.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- mesothelioma (C45.-)
