Prior authorization for MRI

An authorization answer is not a coverage, eligibility, or payment answer. Substrate does not submit prior authorization requests.

This filters authorization rows on this page. It is not a coding dictionary.

MRI

These examples use CPT 70553 only. MRI, CT, and PET are not one requirement. The long descriptor is blank because no AMA-licensed CPT file was available to copy. The outcome in each row is the researched disposition, and the setting limits are listed with it.
