In short

Yes. You can file an internal appeal within 180 days.
Say why no in-network doctor could give this care.
If the plan still says no, you may ask for outside review within 4 months.

What this means

HealthCare.gov says you must file your internal appeal within 180 days (6 months) after you get the denial notice [1]. The plan must finish within 30 days for care you have not had yet, or 60 days for care you already got [1].

A strong appeal explains why no in-network doctor could give this care well. A federal rule gives an example. A plan pays for out-of-network care only when the care "cannot effectively be provided in network." It denies a claim because the provider is out of network. That denial involves medical judgment, so it can go to an outside review [2]. A denial based only on eligibility terms cannot use the federal outside review [3].

Outside (external) review: ask in writing within 4 months after you get the final denial. A standard review is decided within 45 days after the request [4].

Your next step

Ask your doctor for a letter on why no in-network specialist could give this care, and file the internal appeal with it.

Deadline: 180 days after you receive the denial notice; then 4 months for external review.

Check it yourself

Your plan's evidence of coverage says when it pays for out-of-network care. Your state may run its own external review — the final denial letter names who handles it. Whether a pure "provider is out of network" denial with no medical question qualifies is not clear from these sources — "Don't know yet".
