R91.1 – Solitary pulmonary nodule

R91.1 Diagnosis Code: Solitary pulmonary nodule

• A solitary pulmonary nodule (SPN) refers to a round or oval lesion that measures less than 3 centimeters in diameter and is completely surrounded by lung tissue.
• These nodules are typically found incidentally on chest imaging, such as a chest X-ray or computed tomography (CT) scan.
• Most solitary pulmonary nodules are non-cancerous (benign) and may be caused by various factors, including infections, scars, inflammation, or non-infectious granulomas.
• However, some SPNs can indicate lung cancer or other serious conditions, so further evaluation and diagnostic tests are necessary to determine their nature and potential malignancy.

Is R91.1 Billable: Yes

Yes, the ICD-10-CM code R91.1 is billable. Healthcare providers can use this code to document and bill for the diagnosis of a solitary pulmonary nodule encountered during a patient's care. Reimbursement and coverage for medical services related to evaluating and managing SPNs may vary depending on the payer, specific circumstances, and any associated procedures or tests performed.

Clinical Information

• Solitary pulmonary nodules are typically discovered incidentally during routine chest imaging.
• Diagnostic evaluation and management depend on the characteristics and size of the nodule, patient risk factors, and clinical judgment.
• Key clinical considerations for SPNs include determining the likelihood of malignancy and deciding whether further investigations or interventions are necessary.

Additional tests commonly used in the evaluation of SPNs include:

• Positron emission tomography (PET) scan
• CT-guided biopsy or needle aspiration
• Follow-up imaging at specific intervals
• Surgical excision or resection, if warranted
  

Factors that influence the evaluation and management of SPNs include:

• Nodule size
• Patient's age and medical history
• Smoking history
• Radiographic features of the nodule
• Presence of symptoms or associated findings

Synonyms Include:

• Solitary lung nodule
• Pulmonary coin lesion
• Solitary pulmonary mass
• Solitary pulmonary opacity
• Single pulmonary nodule
