Frequently Asked Questions

Can my HMO deny a specialist referral?

HMOs can require PCP referrals and can deny referrals they consider not medically necessary. However, if specialist care IS medically necessary, the denial can be appealed. If no in-network specialist exists, you may be entitled to out-of-network access.

What if I need a specialist who isn't in my network?

Request a network adequacy exception. If your plan cannot provide an in-network specialist with the required expertise within reasonable access standards, they should authorize out-of-network care at in-network rates.
