Summary & Overview
HCPCS M1018: Cancer History, Heavy Smoker, Lung Cancer Screening
HCPCS Level II code M1018 denotes patients with an active diagnosis or history of cancer (excluding basal and squamous cell skin carcinoma), heavy tobacco smokers, and individuals undergoing lung cancer screening. This classification is used nationally to flag high-risk patients for surveillance, screening workflows, and care coordination across outpatient and specialty settings. Its use supports targeted clinical workflows, documentation consistency, and potential quality reporting tied to oncology and tobacco-related care.
Key payers considered in national coverage and utilization analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks for payer coverage practices, context on clinical populations captured by the code, and implications for service lines such as oncology, radiology, and preventive care. The publication highlights typical sites of service, common clinical scenarios where the code applies, and operational considerations for coding and billing teams. Data not available in the input are noted where applicable.
Billing Code Overview
HCPCS Level II code M1018 identifies patients with an active diagnosis or history of cancer (except basal cell and squamous cell skin carcinoma), patients who are heavy tobacco smokers, and lung cancer screening patients. This code is used to denote clinical status related to cancer history and high-risk tobacco exposure.
-
Service type: Risk stratification and monitoring for oncology-related surveillance and lung cancer screening follow-up
-
Typical site of service: Outpatient clinics, oncology clinics, radiology and screening centers, and preventive care settings
Clinical & Coding Specifications
Clinical Context
A typical patient is a 64-year-old current or former heavy smoker referred for low-dose CT (LDCT) lung cancer screening or surveillance imaging following a prior diagnosis of lung malignancy. The patient arrives at an outpatient imaging center or hospital radiology department for a screening LDCT or follow-up CT chest. Registration documents an active or historical diagnosis of cancer (excluding basal cell and squamous cell skin carcinoma) or tobacco use history. The clinical workflow includes verification of indication (screening vs surveillance), informed consent for imaging, review of prior imaging and records, performance of a low-dose non-contrast CT of the chest by an advanced imaging technologist under radiology supervision, image acquisition and reconstruction, radiologist interpretation and generation of a structured radiology report, and communication of results to the referring provider. Typical sites of service include outpatient imaging centers, hospital outpatient radiology departments, and ambulatory surgical centers when related to procedural follow-up. For active oncology patients, services may occur in multidisciplinary cancer centers or inpatient settings when clinically indicated.
