Low‑Dose CT Lung Cancer Screening: Understanding the CPT Code and Clinical Use
Lung cancer remains the leading cause of cancer‑related death worldwide. Early detection through imaging can shift the stage at which the disease is diagnosed, offering a better chance for curative treatment. Low‑dose computed tomography (LDCT) of the chest is the only screening modality that has demonstrated a mortality benefit in high‑risk populations. This article explains what LDCT screening entails, the specific CPT code used for billing, who qualifies, the proven benefits, potential drawbacks, and practical considerations for patients and providers.
What Is Low‑Dose CT Screening?
Low‑dose CT uses a reduced radiation dose compared with standard diagnostic chest CT while still providing sufficient detail to detect small pulmonary nodules. The technique employs specific scanner settings—lower tube current (m
