Lung Cancer Screening ICD-10 Codes & Coverage Info

Lung cancer screening is one of the most effective ways to detect lung cancer early—when treatment can make the biggest difference. For healthcare providers, using the correct ICD-10 codes ensures accurate documentation, billing, and smooth insurance reimbursement.

This guide from Best Writes Links explains the right ICD-10 codes, how to document smoking history, and what to know about insurance coverage for lung cancer screening in 2025.

🩺 What Is Lung Cancer Screening?

Lung cancer screening is a preventive test that helps doctors find early signs of cancer in the lungs before symptoms appear. The screening uses Low-Dose Computed Tomography (LDCT), a special type of CT scan that uses very low radiation.

Early detection through LDCT can reduce lung cancer deaths by catching cancer at an early, more treatable stage.

👥 Who Qualifies for Screening?

According to the U.S. Preventive Services Task Force (USPSTF) and American Cancer Society (ACS), the 2025 screening guidelines recommend annual lung cancer screening for:

• Adults aged 50–80 years

• Individuals with a 20 pack-year or greater smoking history

• Those who currently smoke or quit within the past 15 years

Screening is not needed if the person stopped smoking more than 15 years ago or has a serious health issue that limits life expectancy.

🧾 Correct ICD-10 Codes for Lung Cancer Screening

The main ICD-10 code for preventive lung cancer screening is:

➡️ Z12.2 — Encounter for screening for malignant neoplasm of respiratory organs

This code is used when the purpose of the visit is to screen for lung cancer, not to diagnose symptoms or follow up on an existing condition.

Example:

A 62-year-old patient with a long smoking history visits for a routine LDCT scan.
ICD-10 Code: Z12.2

💡 Supporting ICD-10 Codes for Smoking History

Since smoking history is key to eligibility, supporting ICD-10 codes are needed to show medical necessity. Commonly used codes include:

• Z87.891 — Personal history of nicotine dependence

• F17.210 — Nicotine dependence, cigarettes, uncomplicated

• F17.211 — Nicotine dependence, in remission

Using these codes with Z12.2 helps insurance providers verify eligibility for coverage and ensures accurate records.

💼 Billing and Procedure Code

For billing the actual screening, the procedure code used is:

➡️ G0297 — Low-Dose CT (LDCT) scan for lung cancer screening

To file a clean claim:

• Use Z12.2 as the primary diagnosis code

• Add a smoking history code (Z87.891 or F17.210)

• Include G0297 as the procedure code

• Document a shared decision-making discussion before the test (required by Medicare)

Following these steps ensures compliance and helps avoid claim denials.

💰 Insurance Coverage Details

Medicare and most private insurers cover one annual LDCT screening for eligible patients who meet USPSTF criteria. To qualify for coverage, providers must document:

• Age (50–80 years)

• Smoking history (20+ pack-years)

• Current or former smoker status

• A shared decision-making conversation

• A written physician order for the LDCT scan

When these criteria are met and codes are accurate, screenings are usually covered with no out-of-pocket cost for the patient.

⚠️ Avoid These Coding Mistakes

To prevent billing issues or claim rejections, avoid:

• ❌ Using diagnostic codes (like C34.x) instead of Z12.2 for preventive screenings

• ❌ Missing a smoking history code

• ❌ Forgetting to record the shared decision-making visit

• ❌ Using incorrect or outdated procedure codes

Accurate coding helps ensure timely payment and compliance with 2025 billing standards.

🌿 Final Thoughts

Accurate ICD-10 coding for lung cancer screening is essential for proper billing and preventive care. Providers should always:

• Use Z12.2 as the main screening code

• Add a smoking history code such as Z87.891 or F17.210

• Bill the procedure using G0297

• Document shared decision-making for coverage

Following these steps ensures accurate claims, supports early detection, and keeps patients healthy.
