    Clinical & Coding Specifications

    Clinical Context

    A 64-year-old current smoker with a 35 pack-year history presents for annual low-dose CT lung cancer screening. The patient has no acute respiratory complaints and is asymptomatic; screening is performed after shared decision-making and documentation of eligibility (age 50–80 with ≥20 pack-year history and currently smoking or quit within 15 years). The workflow: pre-authorization or benefit verification is completed when required by the payor; the patient is screened for contraindications (pregnancy, inability to lie supine); technologist confirms identity and screening indication; a low-dose, non-contrast chest CT protocol is obtained and transmitted to the radiology PACS; a radiologist interprets the study, documents Lung-RADS assessment and recommended follow-up; the professional component (interpretation) and technical component (scanner use, technologist) are coded separately when applicable; results are communicated to the referring clinician and the patient with follow-up plans for surveillance, diagnostic evaluation, or smoking cessation counseling as indicated.

    71270Computed tomography, thorax; without contrast followed by contrastUsed when both non‑contrast and contrast sequences are performed in a single encounter following screening abnormalities.
    74177 is not chest-specific and therefore not includedData not applicableData not applicable
    88305Level IV surgical pathology, gross and microscopic examinationMay be used later if tissue obtained after a positive LDCT requires pathologic evaluation.
