Who reviews prior authorization requests for Performing nuclear imaging of the salivary gland using a series of images (CPT 78231)?

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 Performing nuclear imaging of the salivary gland using a series of images (CPT 78231)?

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.
