ICD-10 Code D14.30 – Benign neoplasm of unspecified bronchus and lung (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14.30 – Benign neoplasm of unspecified bronchus and lung
What it is
This code identifies a noncancerous growth in the bronchus or lung when the exact site is not specified. Use it for documented benign neoplasm of the respiratory tract without evidence of malignancy.
Clinical signs
Clinical features vary; refer to documentation. Benign lung or bronchial masses may be found incidentally on imaging or evaluated for cough, wheeze, recurrent infection, or airway obstruction.
When to use this code
Use D14.30 when the provider documents a benign neoplasm involving the bronchus or lung and does not name a more specific site. It also fits cases where pathology or imaging confirms benign behavior, but the record does not distinguish bronchus from lung. Check documentation if the lesion is described as uncertain, metastatic, or malignant.
Do not use for
Do not use this code for malignant neoplasms, carcinoma in situ, or uncertain behavior lesions. Also avoid it when the record specifies a more exact bronchus or lung site that has its own code.
Coding tip
If the chart names the exact bronchial or lung location, code that more specific diagnosis instead of the unspecified code.
