Resources for Clinicians
Clinical guidelines, decision-making tools, and practical resources to integrate lung cancer screening into your practice.
Screening recommendations.
Coverage requirements.
Both consider age and smoking history. Medicare's upper age limit is different from the USPSTF recommendation.
Both: at least 20 pack-years and currently smoking or having quit within the past 15 years. Age alone does not establish eligibility.

Screening Guidelines & Decision Support
Everything you need to identify eligible patients, conduct shared decision-making conversations, and manage screening workflows.
USPSTF 2021 Recommendation
The USPSTF recommends annual LDCT screening for adults aged 50–80 who have at least a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. This is a Grade B recommendation. Stop screening once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to undergo curative lung surgery.
View USPSTF recommendationShared Decision-Making
CMS requires a counseling and shared decision-making visit before a Medicare beneficiary’s first screening LDCT. Document eligibility, use a decision aid, and discuss benefits, potential harms, annual adherence, comorbidities, and willingness to undergo diagnosis and treatment. Offer cessation support to people who currently smoke.
View screening processBilling & Coding
LDCT screening is reported with CPT 71271. For Medicare, the counseling and shared decision-making visit is reported with HCPCS G0296. Verify the payer’s coverage, documentation, and billing requirements. Medicare eligibility includes ages 50–77, no signs or symptoms of lung cancer, at least 20 pack-years, current smoking or quitting within 15 years, and a provider’s order.
Lung-RADS Reporting
The American College of Radiology's Lung-RADS classification system standardizes LDCT screening reporting and management recommendations. Categories range from 0 (incomplete) to 4X (suspicious), each with specific follow-up protocols.

Identifying Eligible Patients
Proactive identification of eligible patients is critical. Many who qualify for screening are never offered it.
EHR Integration
Consider implementing clinical decision support tools in your electronic health record to flag patients who meet USPSTF screening criteria based on age and documented smoking history.
Pack-Year Calculator
Pack-years = (packs per day) × (years smoked). One pack contains 20 cigarettes. This calculation describes smoking exposure; age, time since quitting, health status, and the applicable guideline also matter.
Two packs per day for 10 years also equals 20 pack-years.
Referral Networks
Call 1-844-YES-LUNG for help locating screening resources. Coordinate referrals with local screening programs and confirm each patient’s eligibility, coverage, and follow-up plan.
A clear path from eligibility to follow-up
Build each step into the screening workflow so patients know what happens next.
-
01
Identify
Record age, smoking exposure, quit date, symptoms, and the patient’s overall health.
-
02
Discuss
Use shared decision-making to weigh benefits, harms, and the patient’s preferences.
-
03
Screen
Order the appropriate LDCT and help the patient complete the appointment.
-
04
Follow up
Communicate results, track recommended follow-up, and plan annual screening when appropriate.

Overcoming Common Challenges
Patient Reluctance
Many patients fear a cancer diagnosis or feel stigmatized about their smoking history. Use respectful, nonjudgmental language, explain the purpose of early detection, and invite questions. Frame it positively: “You’ve taken a great step by coming in today.”
False Positives
LDCT can identify nodules and other findings that need follow-up. Many nodules are not cancer. Explain this possibility before screening, use a structured reporting system such as Lung-RADS, and arrange follow-up based on the finding and clinical context.
Smoking Cessation
Screening visits are an ideal "teachable moment" for cessation counseling. Pair screening with evidence-based cessation support. Pharmacotherapy plus behavioral counseling yields the best quit rates.
Adherence
Annual screening adherence drops significantly after the first year. Implement reminder systems, patient navigators, and follow-up protocols to keep patients engaged in their screening program.
