What should be in the clinical notes before requesting Nuclear imaging study using SPECT with a CT scan for at least two areas or multiple days (CPT 78832)?

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.
