You can help keep costs down by referring your patients to specialists their plan covers. Timely referrals help avoid claim reviews so you can get paid sooner.
Our guidelines for patient referrals let us authorize:
- Exact procedure code referrals: These referrals use CPT codes other than 99499. A primary care provider (PCP) should use these referrals when a member needs care for a specific health reason. We only reimburse for procedure codes that match the codes on the referral.
- Consult and treat (C&T referrals): These referrals use CPT code 99499. In most areas, C&T referrals don’t need to include the specialists’ procedures. We pay specialists for performing associated covered services in an office setting based on current claim processing guidelines.
Things to keep in mind:
- If we receive a patient referral without a code: The referral will default to a C&T referral code (99499). Authorized procedures depend on the number of visits on the referral.
- If we receive a patient referral for a procedure that requires prior authorization: We’ll return these requests and ask you to resubmit the code(s) using the prior authorization process. In some instances, we’ll grant a "modified" response where C&T code 99499 replaces the rejected procedure code.
How to submit patient referrals
You can submit an electronic referral* in one of two ways:
