Primary care physicians must decide how to pursue an evaluation of a nodule once it has been identified. The differential diagnosis for pulmonary nodules includes benign and malignant causes. Diameter of 8 mm or more, “ground-glass” density, irregular borders, and doubling time between one month and one year suggest malignancy.
There is a characteristic "volume doubling time" (VDT), the interval it takes for a nodule to double in volume. It's worth keeping in mind that because a nodule is generally spherical, an increase in the diameter by just 28% (such as a 2 mm increase from 7 to 9 mm) actually represents a doubling of the volume of a nodule.
Solitary lung nodule (SLN) is defined as a single, relatively spherical radiological opacity that measures up to 3 cm in size and is surrounded by aerated lung parenchyma. Also, there should be no other associated abnormality including atelectasis, hilar enlargement or pleural effusion.
ICD-10 code R91. 1 for Solitary pulmonary nodule is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
For example, lung mass and multiple lung nodules are specifically indexed to code R91. 8, Other nonspecific abnormal finding of lung field.
R91. 1 - Solitary pulmonary nodule. ICD-10-CM.
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.
R91. 1 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. 1 became effective on October 1, 2021.

ICD-10 | Other nonspecific abnormal finding of lung field (R91. 8)
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.
ICD-9 Code Transition: 786.5 Code R07. 9 is the diagnosis code used for Chest Pain, Unspecified. Chest pain may be a symptom of a number of serious disorders and is, in general, considered a medical emergency.
Tumors that are generally larger than three centimeters (1.2 inches) are called masses. If your tumor is three centimeters or less in diameter, it's commonly called a nodule. If the nodule forms in your lungs, it's called a pulmonary nodule. Hamartomas are the most common type of benign lung nodule.
Multiple nodules in the lungs or multiple pulmonary nodules (MPN) refer to two or more lesions in the lungs. Lung cancer such as bronchoalveolar carcinoma and lymphoma are the most common causes of MPN. These infections result in inflammation, which further forms a granuloma.
Commonly called a “spot on the lung” or a “shadow,” a nodule is a round area that is more dense than normal lung tissue. It shows up as a white spot on a CT scan. Lung nodules are usually caused by scar tissue, a healed infection that may never have made you sick, or some irritant in the air.
