Does Medicare Cover Lung Cancer Screening?

Yes, Medicare covers lung cancer screening once a year, but you have to meet a very specific set of criteria to qualify. If you fit the profile, Medicare Part B covers a low-dose computed tomography (LDCT) scan at 100% of the Medicare-approved amount. That means you pay nothing - no deductible, no copay, and no coinsurance - as long as your doctor accepts assignment.

The rules are strict because this screening is targeted at those with the highest risk. To get Medicare to pay for your annual lung cancer screening, you must meet all of these conditions:

First, you must be between the ages of 50 and 77. Second, you must be asymptomatic, meaning you don't have any signs or symptoms of lung cancer. Third, you must have a tobacco smoking history of at least 20 "pack-years." A pack-year is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years you've smoked. For example, smoking one pack a day for 20 years equals 20 pack-years. Smoking two packs a day for 10 years also equals 20 pack-years.

Finally, you must either be a current smoker or have quit within the last 15 years. And before your first screening, you are required to have a lung cancer screening counseling and shared decision-making visit with your doctor or other qualified healthcare provider. During this visit, they will discuss the benefits and risks of the screening, and you'll receive a written order for the scan.

If you have Original Medicare (Part A and Part B), this is how the coverage works. But remember, the Medicare system offers two paths, not two products. You can stay on the Traditional Medicare path, where you might add a Medigap policy to cover the out-of-pocket costs for other services, or you can choose the Medicare Advantage path.

If you are on a Medicare Advantage plan, your plan is required by law to cover the same preventive services as Original Medicare. That means your lung cancer screening will also be covered at 100% if you meet the criteria and see an in-network provider. However, the rules for which doctors or facilities you can use will depend on your specific Advantage plan's network.

It's important to note that while the screening itself is fully covered, if the scan finds something that requires further testing - like a biopsy or additional imaging - those follow-up procedures are considered diagnostic, not preventive. For diagnostic tests, the standard Part B rules apply: you'll owe your Part B deductible and a 20% coinsurance. If you have a Medigap plan, it will step in to cover that 20% gap.

We know the rules around Medicare can feel like a maze designed to trip you up. But when it comes to your health, you need straight answers, no surprises. You've paid into this system your whole working life, and you deserve to know exactly what you're entitled to. We're on your side of the table, making sure you get the facts without the fluff.

To keep getting the screening covered every year, you'll need a new written order from your doctor each time. The facility where you get the scan must also participate in the Medicare lung cancer screening registry. Your doctor will handle this part, but it's good to be aware that not every imaging center is approved for this specific Medicare benefit.

If you're unsure whether you meet the pack-year requirement or if your smoking history qualifies, the best first step is to schedule a visit with your primary care doctor. They can run the numbers with you and determine if you're eligible for the screening.

Protect what you've earned by understanding your coverage before you walk into the clinic. Whether you're on Traditional Medicare with a supplement or a Medicare Advantage plan, knowing the rules puts you in control of your healthcare decisions.
