Shared-Decision Making References for Lung Cancer Screening
RECOMMENDATION: Medicare Requirements:
It is recommended to complete annual low-dose
computed tomography (LDCT) screening in
asymptomatic patients who exhibit all of the high
risk factors.1-3 (USPSTF Grade B)
High risk factors for lung cancer include:
ξ Age 55-80 years AND
ξ 30 pack-year smoking history AND
ξ Current smoker or smoking cessation
< 15 years ago
Reference: UW Health Preventive Health Care Guideline
Medicare provides coverage to patients aged 55-77 years who also meet the
additional high risk factors outlined on the left. In addition, Medicare requires a lung
cancer screening counseling and shared-decision making visit which includes
documentation of the following:
- Determination of eligibility criteria (age, absence of symptoms of lung cancer,
and smoking pack-years or number of years since quitting);
- Shared decision-making, including use of one or more decision aides, to
include benefits/harms of screening, follow-up diagnostic testing, over-
diagnosis, false-positive rate, and total radiation exposure;
- Counseling on the importance of adherences to annual screening, impact of
comorbidities and ability or willingness to undergo diagnosis and treatment;
- Counseling on the importance of maintaining cigarette smoking abstinence or
smoking cessation (if current smoker)

ξ Smoking cessation
ξ Adhere to annual screening (ongoing process)
ξ Impact of comorbidities
ξ Ability/willingness to undergo diagnosis and treatment
Early detection and treatment resulting in a reduction of lung cancer mortality (20%).2
ξ High false positive rate: The National Lung Screening Trial (NLST) demonstrated that over 3 years,
24.2% of all scans were positive and 39.1% of those screened had at least one positive result.2
However, the vast majority (96.4%) of lung nodules that are detected are benign. 2
ξ False negatives: A negative LDCT result does not guarantee the absence of cancer. In the NLST,
fewer that 1 in 1000 had a cancer diagnosed in the year following a negative scan. 2
ξ Over-diagnosis: Cancers which are detected may not be the ultimate cause of death.
ξ Follow-up diagnostic testing: A positive LDCT result may require additional testing including follow-
up LDCT, bronchoscopy, biopsy, or surgery.4
ξ Radiation exposure: The table below describes the level of radiation exposure during screening.

Comparable background
Additional lifetime risk of fatal cancer for patients over the
age of 50
Chest CT < 3.0 mSv 1-3 years Low (1 in 10, 000 to 1 in 1,000)
Chest Low Dose CT 1.5 mSv 6-18 months Very Low (1 in 100,000 to 1 in 10,000)
Chest X-Ray 0.1 mSv 10-30 days Minimal (1 in 1,000,000 to 1 in 100, 000)
