What Is Lung Cancer Screening?
Lung cancer screening is a test that helps doctors find cancer early, before symptoms appear.
It uses a low-dose CT scan — a special kind of X-ray that takes clear pictures of your lungs using very little radiation.
Doctors suggest screening for people who:
- Are 50 to 80 years old
- Smoke now or used to smoke
- Have smoked for 20 years or more
Finding lung cancer early can make treatment easier and improve recovery chances.
🧾 What Are ICD-10 Codes?
ICD-10 means International Classification of Diseases, 10th Revision.
It’s a system doctors use to record and describe diseases, tests, and screenings with special numbers and letters called codes.
Each code stands for a specific reason for a visit, test, or illness.
These codes help:
- Keep medical records accurate
- Make sure insurance pays correctly
- Track how many people get certain tests or diseases
Using the right ICD-10 code helps doctors and insurance companies understand exactly why a screening is done.
🔢 ICD-10 Codes for Lung Cancer Screening (2025 Update)
Here are the main codes used in 2025 for lung cancer screening and smoking history:
| ICD-10 Code | Description |
| Z12.2 | Screening for malignant neoplasm (cancer) of respiratory organs — used for lung cancer screening |
| Z87.891 | Personal history of nicotine dependence — used for people who used to smoke |
| F17.210 | Nicotine dependence, cigarettes, uncomplicated — for current smokers |
| F17.211 | Nicotine dependence, in remission — used for those who quit smoking |
| Z72.0 | Tobacco use — used for people who still use tobacco occasionally |
These codes help link the reason for screening (Z12.2) with your smoking history (Z87.891 or F17 series).
That connection tells insurance companies the screening is needed for prevention.
💸 Why ICD-10 Codes Matter for Billing
When a doctor orders a lung cancer screening, they use ICD-10 codes to show why the test is being done.
Insurance companies check those codes before paying for the test.
If the right codes are used, your screening is usually covered.
If the wrong code is entered, your insurance might deny payment — even if you qualified.
That’s why accurate coding is so important. It keeps the billing clear and ensures patients don’t get unexpected bills.
🧠 How the Screening & Billing Process Works
- Doctor Visit: You discuss your health and smoking history.
- Eligibility Check: The doctor decides if you qualify for screening.
- Coding Step: Staff add the correct ICD-10 code (like Z12.2) to your medical record.
- Insurance Submission: The clinic sends your claim using the ICD-10 code and a test code (called CPT or HCPCS).
- Coverage Approval: If everything matches, insurance covers the screening.
Simple, right? It’s all about matching the right code with the right reason for care.
🗓️ What’s New in 2025
Here’s what’s changing in 2025 for ICD-10 coding and lung cancer screening:
