Is it possible to get a referral for an mri here on healthtap??

Maybe!: Healthtap has both Healthtap Prime, which is like a virtual urgent care for urgent healthcare issues, prescriptions can be written but an MRI could not be ordered. On Healthtap Concierge, where docs have a virtual presence in addition to their private practices, MRI referral is possible. You must sign up with that doc, & that is like joining that doc's private practice: initial in-person exam 1st

Doubt it: This public site does not offer treatments or referrals. If you want your exam covered by any 3rd party insurance you will need to go through one of the docs on their approved list. This would usually be a preferred primary care person or specialist. Referrals become legal documents & providing one without a direct patient relationship, exam & records can result in loss or restriction of license
