Summary & Overview
HCPCS Level II C8936: Magnetic Resonance Angiography, Upper Extremity
HCPCS Level II code C8936 represents a magnetic resonance angiography (MRA) study of the upper extremity performed first without contrast and then with contrast. This two-part imaging protocol provides both non-contrast vascular assessment and contrast-enhanced visualization to improve diagnostic accuracy for arterial and venous pathology. Nationally, documenting and coding dual-phase MRA studies affects imaging utilization, payer coverage determinations, and facility billing workflows.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical purpose of this MRA protocol, the typical sites of service where it is delivered (outpatient imaging centers and hospital outpatient radiology departments), and the relevance to payer policy and billing operations. The publication reviews common modifiers associated with imaging services, outlines expected documentation elements, and summarizes how this service is positioned in payer coverage frameworks.
This analysis provides benchmarks for coding practice, highlights policy considerations affecting coverage and claims processing, and situates the procedure within clinical workflows for vascular imaging of the upper extremity. Data not available in the input are noted where applicable.
Billing Code Overview
HCPCS Level II code C8936 describes magnetic resonance angiography without contrast followed by with contrast, upper extremity. The service type is diagnostic imaging (magnetic resonance angiography) performed as a two-part study that includes an initial non-contrast MRA followed by contrast-enhanced imaging. The typical site of service is an outpatient imaging center or hospital outpatient radiology department where MRI/MRA scanners and contrast administration capability are available.

Clinical & Coding Specifications
Clinical Context
A 62-year-old right-hand–dominant patient with progressive ischemic rest pain, cold intolerance, and diminished radial pulse presents to vascular clinic after a duplex ultrasound was inconclusive for arterial stenosis of the upper extremity. The vascular surgeon orders magnetic resonance angiography (MRA) of the upper extremity performed without contrast followed by with contrast (C8936) to evaluate arterial anatomy from the subclavian artery through the distal forearm, identify focal stenosis, occlusion, or embolic disease, and plan revascularization.
Clinical workflow:
-
Referral from vascular clinic for diagnostic vascular imaging.
-
Pre-procedure screening for contraindications to MRI and gadolinium contrast (e.g., pacemaker, severe renal impairment, prior contrast reaction).
-
Patient arrives at outpatient imaging center or hospital radiology department (typical site of service: outpatient imaging center or hospital outpatient department).
-
Technologist performs non-contrast MRA sequences to assess baseline flow and vessel patency, followed by IV gadolinium-enhanced sequences to better delineate stenosis, collateral circulation, and vessel wall pathology.
-
Radiologist interprets combined non-contrast and contrast-enhanced images, generates a report describing location and severity of lesions, and provides findings for the referring vascular specialist to guide intervention or medical management.
-
Images and report are transmitted to the electronic medical record and the referring provider; typical clinical next steps include planning for angiography with possible endovascular intervention or surgical bypass if significant stenosis or occlusion is confirmed.
