ICD-10 Code D14.3 – Benign neoplasm of bronchus and lung (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14.3 – Benign neoplasm of bronchus and lung
What it is
D14.3 identifies a noncancerous tumor of the bronchus or lung. Use it when the provider documents a benign neoplasm in these respiratory structures.
Clinical signs
Clinical features vary; refer to documentation. These lesions may be found incidentally on imaging or after evaluation of cough, wheeze, hemoptysis, or airway obstruction.
When to use this code
Use this code when the record clearly states a benign neoplasm of the bronchus or lung. It also fits documented pathology or imaging findings confirming a nonmalignant tumor in these sites. If the note only says “lung mass” or “pulmonary nodule,” check documentation before assigning D14.3.
Do not use for
Do not use D14.3 for malignant lung tumors, metastatic disease, or lesions documented as uncertain behavior. If the diagnosis is a nonspecific nodule or mass without confirmation, check documentation.
Coding tip
Verify the exact anatomic site and benign nature in the provider note before coding D14.3.
