Find in-network specialists by insurance plan, before you send the referral.
Search by specialty and insurance plan, see referral and prior-authorization rules, and see where public sources disagree.
Now serving colorectal surgery and neurosurgery practices in Maricopa County; other specialties by inquiry.
Why referrals bounce
A specialist's address, phone number or plan network can be listed differently in the national NPI registry, CMS data and each health plan's directory. When sources disagree, referrals can go to the wrong office or to a specialist who isn't in the patient's network. Verinex puts those sources side by side.
How it works

See specialists listed in that plan's network, with the plan's referral and prior-authorization rules where we have them on file.
Open any specialist to compare what each public source says, with dates.
Who it's for
