ICD-10 Code D14 – Benign neoplasm of middle ear and respiratory system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14 – Benign neoplasm of middle ear and respiratory system
What it is
D14 identifies a noncancerous tumor in the middle ear or respiratory system. Use it when documentation states a benign neoplasm in one of these sites and does not specify a more exact subcategory.
Clinical signs
Clinical features vary; refer to documentation. Benign masses may cause local obstruction, hearing changes, cough, or other site-specific symptoms, but the diagnosis should be supported by imaging, endoscopy, or pathology when available.
When to use this code
Use D14 when the provider documents a benign neoplasm involving the middle ear or respiratory tract and no more specific ICD-10-CM code is given. It is appropriate for confirmed benign tumors, including cases recorded after biopsy or surgical excision. If the record only notes a mass or lesion, check documentation before assigning this code.
Do not use for
Do not use D14 for malignant neoplasms, inflammatory disease, or unspecified symptoms without a documented benign tumor. If the site is outside the middle ear or respiratory system, code the documented location instead.
Coding tip
Verify the exact anatomic site and pathology wording, because D14 is a broad category and a more specific code may apply.
