CPT® Code 71045

What is CPT® 71045?

CPT® 71045 is used to report a single-view frontal chest X-ray. This radiologic exam captures an image of the chest primarily used to evaluate the lungs, heart, bones, and chest wall. The single frontal (posteroanterior or anteroposterior) view is often the initial imaging test ordered to diagnose or monitor various thoracic conditions.

When to Use CPT® 71045

Use CPT® 71045 when:

  • A single frontal chest radiograph is medically necessary for evaluation or follow-up of respiratory or cardiac conditions.
  • The provider requires a quick screening tool for symptoms such as cough, chest pain, shortness of breath, or trauma.
  • Follow-up imaging is needed to monitor known conditions like pneumonia, heart failure, or rib fractures.

Typical clinical scenarios include:

  • Initial assessment of suspected pneumonia or bronchitis
  • Screening for pleural effusion or pneumothorax
  • Evaluation of cardiac silhouette size in heart failure
  • Trauma evaluation for rib fractures or chest injuries

Key Billing Information

  • CPT® 71045 refers specifically to a single frontal chest image only.
  • Additional views, such as lateral chest X-rays, require separate billing with CPT® 71046.
  • When bundled with other imaging studies or procedures, ensure correct coding to avoid duplication.
  • Appropriate ICD-10 diagnosis codes supporting medical necessity must accompany the claim.

Documentation Requirements

To support CPT® 71045 billing, documentation should include:

  • Clinical indication for the chest X-ray
  • Date and time of the imaging procedure
  • Description of the findings in the radiology report
  • Provider review and incorporation of imaging results into the patient’s management plan

Why Accurate Coding Matters

Accurate use of CPT® 71045 ensures compliance with payer requirements and facilitates timely reimbursement. Precise coding helps avoid claim denials due to improper billing of imaging services and supports continuity of care through proper documentation of diagnostic testing.
