Most lung nodules seen on CT scans are not cancer. They are more often the result of old infections, scar tissue, or other causes. But tests are often needed to be sure a nodule is not cancer. Most often the next step is to get a repeat CT scan to see if the nodule is growing over time.
• The full definition for Rt. Infrahilar nodule can be broken down to its four parts, some, where quoted, described by medilexicon.com, an online medical dictionary. • 'Rt.' is an abbreviation of right, as in the position sense i.e. To the right. • 'Infra' means "a position below the part denoted by the word to which it is joined."
The nodule is small. A benign lung tumor is an abnormal growth of tissue that serves no purpose and is found not to be cancerous. Benign lung tumors may grow from many different structures in the lung. Determining whether a nodule is a benign tumor or an early stage of cancer is very important.
ICD-10-CM Code for Solitary pulmonary nodule R91. 1.
A lung (pulmonary) nodule is an abnormal growth that forms in a lung. You may have one nodule on the lung or several nodules. Nodules may develop in one lung or both. Most lung nodules are benign (not cancerous). Rarely, pulmonary nodules are a sign of lung cancer.
For example, lung mass and multiple lung nodules are specifically indexed to code R91. 8, Other nonspecific abnormal finding of lung field.
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.
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.
A lung nodule (or mass) is a small abnormal area that is sometimes found during a CT scan of the chest. These scans are done for many reasons, such as part of lung cancer screening, or to check the lungs if you have symptoms. Most lung nodules seen on CT scans are not cancer.

Diagnosis. The most common cause of multiple lung nodules is metastatic cancer.
ICD-10-CM Diagnosis code R91.1 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.
A pulmonary nodule is a rounded or irregular opacity, which may be well or poorly defined, measuring ≤3 cm in diameter (6). A pulmonary nodule is considered small if its largest diameter is 10 mm or less. A micronodule is considered a pulmonary nodule <3. mm (6,7).
A CT scan usually isn't enough to tell whether a lung nodule is a benign tumor or a cancerous lump. A biopsy is the only way to confirm a lung cancer diagnosis. But the nodule's characteristics as seen on a CT scan may offer clues.
However, your doctor may suspect a lung nodule is cancerous if it grows quickly or has ridged edges. Even if your doctor believes the nodule is benign or noncancerous, he or she may order follow-up chest scans for some time to monitor the nodule and identify any changes in size, shape or appearance.
If the CT scan shows small nodules (less than a centimeter wide, or about the size of a green pea), the probability of them being cancerous is low. Larger nodules are more worrisome. Rounded nodules are less likely to be cancerous than spiculated (having jagged edges) ones.
Nodules between 6 mm and 10 mm need to be carefully assessed. Nodules greater than 10 mm in diameter should be biopsied or removed due to the 80 percent probability that they are malignant. Nodules greater than 3 cm are referred to as lung masses.
The most common causes of lung nodules are inflamed tissue due to an infection or inflammation (called granulomas) or benign lung tumors (such as hamartomas). Less common, malignant lung nodules are typically caused by lung cancer or other cancers that have spread to the lungs (metastatic cancer).
Growth: Cancerous lung nodules tend to grow fairly rapidly with an average doubling time of about four months, while benign nodules tend to remain the same size over time.
