- 012Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CCsurgical
- 013Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCCsurgical
Excludes2 — not included here
The conditions below are not part of C05.1, but a patient may have both at the same time. When documentation supports it, C05.1 and the excluded code may both be reported.
- malignant neoplasm of nasopharyngeal surface of soft palate (C11.3)
Excludes1 — never code together — inherited from C05
The conditions below can never be reported together with C05.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- Kaposi's sarcoma of palate (C46.2)
