Summary & Overview
HCPCS Level II G9347: Incidentally Detected Pulmonary Nodule — Follow-Up Not Documented
HCPCS Level II code G9347 denotes that recommended follow-up recommendations for incidentally detected pulmonary nodules were not documented and no reason was provided. Nationally, this code flags gaps in documentation and adherence to guideline-based follow-up after incidental lung nodule detection—an issue with implications for patient safety, care coordination, and quality measurement. The code is relevant across payers and settings where imaging identifies pulmonary nodules, particularly radiology departments and outpatient clinics.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical meaning and typical use, plus guidance on what the publication addresses: documentation benchmarks, administrative and policy considerations affecting national adoption, and the clinical context surrounding incidental pulmonary nodule follow-up. The report summarizes how G9347 is used to identify documentation deficiencies, potential impacts on quality reporting and payer audits, and where to look for related coding and policy updates.
Data not available in the input indicates specific payer-level rates, modifier usage patterns, ICD-10 pairings, and related code mappings are not provided here.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A 64-year-old current smoker undergoes an outpatient low-dose chest CT for lung cancer screening at a freestanding imaging center. The radiologist identifies a 6 mm incidentally detected solitary pulmonary nodule in the right upper lobe. The report documents size, location, and attenuation but does not include follow-up recommendations aligned with established guidelines (for example, Fleischner Society or Lung-RADS) and does not state a reason for omitting recommendations. The typical workflow: CT technologist performs imaging, radiologist interprets and finalizes the report, report is transmitted to the ordering primary care physician or pulmonologist and uploaded to the electronic medical record. A coding/billing specialist assigns HCPCS Level II code G9347 to denote that follow-up recommendations were not documented according to recommended guidelines and no reason was provided. Typical site of service: outpatient imaging center, hospital outpatient radiology department, or ambulatory surgery center when imaging is performed there.
