Lung Cancer Screening: ICD-10 Coding, Criteria & Coverage
Lung cancer is one of the most serious cancers worldwide, but when detected early, treatment success rates improve significantly. That’s why lung cancer screening has become a key part of preventive healthcare.
For providers, understanding the correct ICD-10 coding, eligibility criteria, and coverage rules is essential for accurate documentation and reimbursement. This guide from Best Writes Links explains everything you need to know for 2025.
🩺 What Is Lung Cancer Screening?
Lung cancer screening is a medical test used to find signs of lung cancer before symptoms develop. The primary method used is Low-Dose Computed Tomography (LDCT), which captures detailed images of the lungs with minimal radiation exposure.
The purpose of screening is early detection — finding cancer at a stage when it’s easier to treat and the chances of recovery are higher.
🧠 Who Qualifies for Lung Cancer Screening?
According to the U.S. Preventive Services Task Force (USPSTF) and current 2025 guidelines, lung cancer screening is recommended for individuals who meet these criteria:
- Age: Between 50 and 80 years old
- Smoking history: At least 20 pack-years (one pack per day for 20 years or two packs per day for 10 years)
- Smoking status: Current smoker or quit within the last 15 years
Screening should not continue if the person has not smoked in over 15 years or has health issues that limit life expectancy.
Correctly documenting these factors is crucial for insurance approval and ICD-10 coding.
🧾 ICD-10 Coding for Lung Cancer Screening
Proper ICD-10 coding ensures that the reason for screening is clear and that claims are paid without delay.
The primary ICD-10 code for lung cancer screening is:
- Z12.2 — Encounter for screening for malignant neoplasm of respiratory organs
This code should always be used when the purpose of the visit is preventive lung cancer screening, even if no symptoms are present.
Supporting Codes for Smoking History
To show patient eligibility, one of the following should also be added:
- Z87.891 — Personal history of nicotine dependence
- F17.210 — Nicotine dependence, cigarettes, uncomplicated
- F17.211 — Nicotine dependence, in remission
Including a smoking-related code helps prove that the screening meets medical necessity.
💼 Billing & Procedure Code
When performing LDCT for lung cancer screening, providers should use the following HCPCS code for billing:
- G0297 — Low-Dose CT (LDCT) scan for lung cancer screening
This procedure code should be linked with Z12.2 and the appropriate smoking history code to ensure clean claims and compliance with payer requirements.
💰 Insurance Coverage for Lung Cancer Screening
Most major insurance companies, including Medicare and Medicaid, cover annual LDCT lung cancer screening for eligible patients. However, certain conditions must be met:
- The patient must meet the USPSTF criteria for age and smoking history.
- A written order from a healthcare provider is required.
- The provider must document shared decision-making, explaining the risks and benefits of screening.
Medicare allows one covered LDCT per year if all eligibility criteria are documented correctly. Missing documentation may result in claim denials or nonpayment.
⚠️ Common Documentation & Coding Errors
Healthcare teams should avoid these frequent mistakes:
- ❌ Using diagnostic codes (like C34.x) instead of screening codes (Z12.2)
- ❌ Failing to document smoking history or eligibility criteria
- ❌ Omitting the LDCT procedure code (G0297)
- ❌ Submitting claims without shared decision-making documentation
Following these steps helps ensure accurate records and consistent reimbursement.
🌿 Summary
Using the correct ICD-10 codes for lung cancer screening helps ensure compliance, proper billing, and accurate tracking of preventive services. Always document patient eligibility, smoking history, and provider recommendations in the record.
For 2025, remember this simple rule:
- Z12.2 is the main code for screening
- Add F17.210 or Z87.891 for smoking history
- Link to G0297 for the LDCT procedure
Staying up to date with ICD-10 and insurance guidelines is key to smooth billing and quality care.
