Which payers have published criteria for MRI thoracic spine without and with contrast (CPT 72157)?

The imaging guidelines used by Aetna, Anthem BCBS, Cigna, Medicare, UnitedHealthcare include criteria that apply to this study. Whether a specific patient's plan requires prior authorization depends on the plan, so confirm on the payer's portal or by phone before scheduling.

Who reviews prior authorization requests for MRI thoracic spine without and with contrast (CPT 72157)?

Most commercial payers hand imaging reviews to a radiology benefit manager. For the payers tracked here, requests are reviewed using guidelines from eviCore, Carelon, CMS, UnitedHealthcare / eviCore. The request is submitted through that organization's portal rather than the health plan's general line.

What should be in the clinical notes before requesting MRI thoracic spine without and with contrast (CPT 72157)?

Reviewers look for a recent office visit that documents the symptoms and how long they have lasted, exam findings, results of any earlier imaging, treatments already tried and how the patient responded, and the specific question the study is expected to answer. The diagnosis code on the request should match what the notes describe.

What can be done if MRI thoracic spine without and with contrast (CPT 72157) is denied?

Read the denial letter for the stated reason, then request a peer-to-peer conversation between the ordering clinician and the reviewing physician, which often resolves missing-information denials. If that fails, file a written appeal that answers the stated reason directly and attach the supporting notes. The denial letter lists the deadline and where to send the appeal.
