Lung Cancer Screening (LDCT)

Preventive Care

Lung cancer screening is for people at higher risk, mainly based on smoking history and age.

Quitting smoking is still the biggest prevention step.
Ask whether you meet criteria for low-dose CT screening.
Discuss pros/cons (false positives, follow-up testing).

Medicare covers lung cancer screening with low-dose CT under Part B for eligible beneficiaries.

Eligibility and frequency limits apply.
Shared decision-making requirements may apply.

Key takeaways

LDCT screening is risk-based; confirm eligibility.
Quitting smoking remains the biggest win.
Expect counseling and criteria checks.

Good to Know

Provider Accepts Assignment

In Original Medicare, “accepts assignment” means a provider agrees to Medicare’s approved amount as full payment (with you paying any required deductible/coinsurance). For many preventive services, using a provider who accepts assignment can help keep your costs lower and more predictable.

Frequency Limits

Many Medicare preventive services have frequency limits, meaning Medicare covers them only as often as allowed (for example, once every 12 months, once every five years, or once in your lifetime). The schedule varies by service.

Eligibility Rules

Many preventive services are covered only if you meet Medicare’s eligibility rules. These rules can include your age, risk factors, medical history, lab results, diagnoses, or timing (for example, being “at risk” for a screening).
