Summary & Overview
CPT 76498: Unlisted Magnetic Resonance Diagnostic or Interventional Procedure
CPT code 76498 represents an unlisted magnetic resonance (MR) procedure used when no specific CPT descriptor exists for a performed MR diagnostic or interventional service. Nationally, unlisted codes like 76498 are important because they enable billing for novel, atypical or evolving MR techniques that lack discrete codes, supporting continued patient access to advanced imaging and MR-guided interventions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise explanation of the code’s clinical scope and typical sites of service, plus an overview of payer coverage considerations. The publication outlines benchmark elements commonly reviewed for unlisted MR services — such as documentation requirements, medical necessity justification, and payer-specific prior authorization and payment pathways — and highlights policy trends affecting reimbursement for unlisted imaging procedures.
This summary is intended to inform clinicians, billing professionals and policy analysts about the role of 76498 in billing workflows, what to expect from payers nationally, and the types of documentation and coding contexts that are most relevant when reporting an unlisted MR procedure. Data not available in the input is noted where specifics are required.
Billing Code Overview
CPT code 76498 is an unlisted magnetic resonance procedure used to report magnetic resonance services that do not have a specific CPT code. This code applies when a provider performs a magnetic resonance technique either to establish a diagnosis or as part of an interventional procedure to treat a condition.
-
Service type: Magnetic resonance diagnostic or interventional procedure
-
Typical site of service: Hospital outpatient departments, freestanding imaging centers, ambulatory surgical centers, or other facilities where magnetic resonance imaging and MR-guided procedures are performed
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with a complex soft-tissue mass in the pelvis is referred for a magnetic resonance procedure that does not match a specific listed MRI CPT code. The ordering physician requests a tailored magnetic resonance study performed by an MRI-capable interventional radiologist to characterize the lesion and potentially guide a percutaneous biopsy. The patient arrives at an outpatient imaging center or hospital radiology suite, completes screening for MRI safety, and has IV contrast administered for enhanced tissue characterization. The MRI technologist performs targeted sequences directed by the radiologist, who may remain in the scanner room for real-time localization of the lesion for subsequent interventional access. Images are reviewed by the interpreting physician, a diagnostic radiologist or interventional radiologist, and a formal report is issued to the referring clinician for diagnostic or therapeutic planning.
