ICD-10 Code D14.31 – Benign neoplasm of right bronchus and lung (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D14.31 – Benign neoplasm of right bronchus and lung
What it is
This code identifies a noncancerous tumor in the right bronchus or right lung. It is used when documentation clearly states a benign neoplasm on the right side.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an incidental imaging finding, cough, wheeze, or airway obstruction if the lesion affects bronchial flow.
When to use this code
Use D14.31 when the provider documents a benign neoplasm specifically involving the right bronchus or right lung. Apply it for pathology-confirmed or clearly diagnosed benign tumors on the right side. If the record only says “lung mass” or does not specify laterality, check documentation.
Do not use for
Do not use this code for malignant lung or bronchial tumors, metastatic disease, or unspecified masses. If the lesion is not documented as benign, this code is not appropriate.
Coding tip
Verify both benign behavior and right-sided location before assigning D14.31.
