Updated ICD-10 Codes for Lung Cancer Screening
Lung cancer screening is a critical preventive measure that helps detect lung cancer early, often before symptoms appear. In 2025, accurate use of ICD-10 codes is more important than ever for correct documentation, billing, and insurance claims.
This guide from Best Writes Links explains the updated ICD-10 codes for lung cancer screening, current screening guidelines, and how to document properly to ensure compliance and reimbursement.
🩺 What Is Lung Cancer Screening?
Lung cancer screening uses a Low-Dose Computed Tomography (LDCT) scan to check for early signs of lung cancer in high-risk individuals. The scan provides detailed images of the lungs using very small amounts of radiation and can detect nodules or abnormalities long before symptoms develop.
The goal is simple: detect lung cancer early, when it’s easier to treat and survival chances are highest.
👥 Who Should Get Screened?
According to the U.S. Preventive Services Task Force (USPSTF) and American Cancer Society (ACS) 2025 guidelines, lung cancer screening is recommended for adults who:
- Are 50 to 80 years old
- Have a 20 pack-year smoking history (one pack a day for 20 years or two packs a day for 10 years)
- Currently smoke or quit within the past 15 years
Screening is not typically advised for individuals with serious health conditions that limit life expectancy or for those who quit smoking more than 15 years ago.
🧾 Updated ICD-10 Codes for Lung Cancer Screening (2025)
The main ICD-10 code for preventive lung cancer screening remains:
➡️ Z12.2 — Encounter for screening for malignant neoplasm of respiratory organs
This code is used when a patient receives an LDCT scan for routine lung cancer screening without any symptoms or existing diagnosis.
To support this primary code, providers should also include a secondary code to document smoking history or nicotine dependence, such as:
- Z87.891 — Personal history of nicotine dependence
- F17.210 — Nicotine dependence, cigarettes, uncomplicated
- F17.211 — Nicotine dependence, in remission
Including these ensures that the patient’s screening meets medical necessity criteria for insurance coverage.
💼 Billing and Procedure Code
When billing for a lung cancer screening LDCT scan, use the HCPCS code:
➡️ G0297 — Low-Dose CT scan for lung cancer screening
For accurate billing:
- Use Z12.2 as the primary diagnosis code
- Add a smoking history or nicotine dependence code (Z87.891 or F17.210)
- Document a shared decision-making visit before screening
- Include the G0297 code for the procedure itself
This combination of ICD-10 and HCPCS codes ensures correct claim submission and compliance with payer policies.
💰 Insurance Coverage for Lung Cancer Screening
Most insurance companies, including Medicare, cover annual LDCT screenings for eligible patients who meet the USPSTF criteria. To qualify, documentation must include:
- Patient’s age (50–80)
- Smoking history (20+ pack-years)
- Current or former smoker status
- A shared decision-making discussion with the patient
- A physician’s written order for the LDCT scan
When these elements are documented with correct ICD-10 codes, insurance coverage is usually approved without cost to the patient.
⚠️ Common Coding Mistakes to Avoid
To prevent denials and delays, avoid these common coding errors:
- ❌ Using diagnostic codes (C34.x) instead of screening code (Z12.2) for preventive visits
- ❌ Failing to include a smoking history code
- ❌ Missing documentation of the shared decision-making visit
- ❌ Incorrect use of procedure code (G0297 must match LDCT screening)
Following proper coding procedures ensures both compliance and payment accuracy.
🌿 Final Thoughts
Accurate ICD-10 coding is vital for effective lung cancer screening documentation and billing. The right combination of Z12.2, smoking history codes, and G0297 ensures your claims are processed correctly and your patients receive timely preventive care.
By staying current with the 2025 ICD-10 updates, healthcare providers can improve billing accuracy, maintain compliance, and help save more lives through early detection.
