From the Guidelines

Medicare covers lung cancer screening with low-dose computed tomography (LDCT) once per year for individuals who meet specific criteria, including being between 55 and 77 years old, having a tobacco smoking history of at least 30 pack-years, and being a current smoker or having quit within the last 15 years. To qualify, individuals must also have no signs or symptoms of lung cancer and undergo a lung cancer screening counseling and shared decision-making visit with a qualified medical provider, as required by the Centers for Medicare and Medicaid Services (CMS) 1. This visit must include a discussion of the benefits and harms of LDCT screening, including false positives and unnecessary procedures, as well as the importance of adherence to screening and follow-up testing 1.

The criteria for Medicare coverage of lung cancer screening are as follows:

  • Age: 55-77 years old
  • Smoking history: at least 30 pack-years, with tobacco use within the prior 15 years
  • Comorbid conditions: no conditions that substantially limit life expectancy
  • Symptoms: no symptoms suggestive of lung cancer
  • Shared decision making: required, including a discussion of benefits, harms, follow-up testing, and importance of adherence
  • Radiologist eligibility: current certification with American Board of Radiology (or equivalent) and training in diagnostic radiology and radiation safety
  • Screening facility eligibility: accredited advanced diagnostic imaging center with training and experience in LDCT screening

It is essential to note that the CMS coverage determination requires a prescreening visit with a qualified medical provider to confirm eligibility and to engage in counseling and shared clinical decision making 1. This requirement reflects the importance of informed decision making and patient-centered care in lung cancer screening. By prioritizing shared decision making and patient education, healthcare providers can ensure that individuals make informed decisions about their care and receive high-quality, patient-centered care 1.
