Summary & Overview
CPT 70548: Magnetic Resonance Angiography of the Head with and without Contrast
CPT code 70548 represents magnetic resonance angiography (MRA) of the head, performed first without contrast and then with contrast material, including further imaging sequences. This advanced radiology procedure is critical for assessing cerebral blood vessels and is widely used in the diagnosis and management of neurological and vascular conditions. The service is typically provided in outpatient hospital settings, reflecting its accessibility and importance in routine clinical care.
Major national payers covering this procedure include Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare. The publication offers a comprehensive overview of payer coverage, clinical context, and relevant billing benchmarks for 70548.

This information is essential for healthcare professionals, administrators, and policy analysts seeking to stay informed about national trends and requirements for MRA head procedures.
CPT Code Overview
CPT code 70548 describes a magnetic resonance angiography (MRA) of the head performed without contrast material, followed by imaging with contrast material and additional sequences. This procedure is a specialized radiology service used to evaluate blood vessels in the head, providing detailed images for diagnostic purposes. The typical site of service for this procedure is an outpatient hospital setting, classified as Place of Service 22. MRA of the head is essential for diagnosing and monitoring various cerebrovascular conditions and is commonly utilized in clinical practice.
Clinical & Coding Specifications
Clinical Context
A patient presents to the outpatient hospital with neurological symptoms such as sudden onset of headache, visual disturbances, or signs suggestive of cerebrovascular disease. The physician suspects a vascular abnormality in the head, such as an aneurysm, stenosis, or possible neoplastic involvement affecting cerebral blood vessels. To evaluate the cerebral vasculature, the provider orders a magnetic resonance angiography (MRA) of the head. The procedure involves initial imaging without contrast, followed by administration of contrast material and further imaging sequences to enhance visualization of the blood vessels. This workflow is typical for patients with suspected neurosyphilis, cerebrovascular syphilis, or malignant neoplasms affecting the head and lip regions, as indicated by the associated ICD-10 diagnoses.
