ICD-10 Code D10.6 – Benign neoplasm of nasopharynx (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D10.6 – Benign neoplasm of nasopharynx
What it is
D10.6 identifies a noncancerous growth arising in the nasopharynx, the upper part of the throat behind the nose. It is used when documentation clearly states a benign neoplasm in this location.
Clinical signs
Clinical features vary; refer to documentation. Patients may have nasal obstruction, ear symptoms, or a visible or reported mass in the nasopharynx, but the diagnosis should be supported by clinical or pathologic confirmation.
When to use this code
Use D10.6 when the provider documents a benign nasopharyngeal tumor, mass, or neoplasm. It also fits cases confirmed by biopsy or specialist evaluation as benign and specifically located in the nasopharynx.
Do not assign it for nonspecific throat complaints without a documented neoplasm. If the record only says “mass” or “lesion,” check documentation to confirm benign behavior and precise anatomic site.
Do not use for
Do not use this code for malignant, in situ, or uncertain neoplasms of the nasopharynx. It is also wrong for inflammatory, infectious, or traumatic lesions that are not true benign tumors.
Coding tip
Confirm both benign behavior and nasopharyngeal site in the provider note before coding D10.6.
