Do diagnostic procedures, including CAT scans, MRIs and special X-rays need a referral?
Normally, they do not need a separate referral authorization as long as the PCP or a specialist to whom we have an authorized referral orders the diagnostic tests. Some diagnostic tests do require an authorization, such as bone mineral density studies. For a list of diagnostic procedures requiring authorization, refer to the ODS referral guidelines. Use of noncontracted providers may result in lower benefits or, in some cases, no benefits at all.
