ICD-10 Code D14.4 – Benign neoplasm of respiratory system, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14.4 – Benign neoplasm of respiratory system, unspecified
What it is
D14.4 identifies a noncancerous tumor of the respiratory system when the site is not specified. Use it for a benign neoplasm documented in the airway, lung, or related respiratory structure, but not named more precisely.
Clinical signs
Clinical features vary; refer to documentation. Benign respiratory tumors may be found incidentally or after cough, wheeze, dyspnea, hemoptysis, or airway obstruction prompts evaluation.
When to use this code
Use D14.4 when the provider documents a benign neoplasm of the respiratory system and does not identify a more specific site. It also fits when the record confirms benign behavior but the exact respiratory location remains unspecified. Check documentation if laterality or organ site is available.
Do not use for
Do not use this code for malignant neoplasms, carcinoma in situ, or uncertain behavior tumors. If the lesion is coded to a specific respiratory site, select the more precise code instead.
Coding tip
Code the documented anatomic site whenever possible; use D14.4 only when the respiratory location is truly unspecified.
