R91 - Abnormal findings on diagnostic imaging of lung.
Lung nodules — small masses of tissue in the lung — are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size.
For example, lung mass and multiple lung nodules are specifically indexed to code R91. 8, Other nonspecific abnormal finding of lung field.
Solitary pulmonary nodule (SPN) is defined as a single lung opacity of size less than 3 cm. It is usually discrete and does not attach to the lung border or pleura. Associated lymphadenopathy is characteristically absent.
In general, nodules that are less than 6 mm (1/4 inch) in diameter are followed with a repeat chest CT scan due to the low risk of cancer (ten percent or less), unless some other feature is felt to increase the probability of cancer. Nodules between 6 mm and 10 mm need to be carefully assessed.
A single lung lesion that is characterized by a small round mass of tissue, usually less than 1 cm in diameter, and can be detected by chest radiography. A solitary pulmonary nodule can be associated with neoplasm, tuberculosis, cyst, or other anomalies in the lung, the chest wall, or the pleura.
ICD-10-CM Diagnosis code R91.1 R91. 1 is a valid ICD-10-CM diagnosis code meaning 'Solitary pulmonary nodule'. It is also suitable for: Coin lesion lung. Solitary pulmonary nodule, subsegmental branch of the bronchial tree.
Other nonspecific abnormal finding of lung field R91. 8 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM R91. 8 became effective on October 1, 2021.
