ICD-10 Code D14.0 – Benign neoplasm of middle ear, nasal cavity and accessory sinuses (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14.0 – Benign neoplasm of middle ear, nasal cavity and accessory sinuses
What it is
D14.0 identifies a noncancerous growth in the middle ear, nasal cavity, or accessory sinuses. Use it when the record documents a benign neoplasm in one of these sites.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a visible or imaging-detected mass, obstruction, or pressure-related symptoms, but the diagnosis should be supported by the recorded site and benign nature.
When to use this code
Use D14.0 when the provider documents a benign tumor in the middle ear, nasal cavity, or paranasal sinus region. It also fits pathology, endoscopy, or imaging reports that clearly identify a benign neoplasm at one of these locations. If the site is unclear, check documentation.
Do not use for
Do not use this code for malignant, uncertain, or metastatic tumors. Do not assign it for inflammatory polyps, cysts, or nonspecific nasal/sinus masses unless the record explicitly states a benign neoplasm.
Coding tip
Verify both the anatomic site and the benign pathology wording before coding D14.0.
