Do You Need Prior Authorization for Out-of-Network Care?

Updated July 9, 2026 5 min read

Prior authorization rules already feel like an extra hoop when care stays inside a plan’s network. Step outside that network, and the same rules tend to get stricter rather than looser, which catches a lot of people off guard.

The short answer

Yes — out-of-network care very often requires prior authorization, and in many plan designs it requires it more strictly than the same care would in-network. Some plans that waive authorization for certain in-network services still require it once a patient goes outside the network, and a few plan types don’t cover out-of-network care at all except in emergencies, which makes the authorization question secondary to a coverage question.

Why the bar is higher out-of-network

Health plans build their networks partly to steer utilization toward providers they’ve negotiated rates and quality standards with. Out-of-network care removes both of those levers, so plans lean more heavily on prior authorization as a way to review whether the care is medically necessary and whether an in-network alternative could reasonably have been used instead. That review can ask for more clinical documentation than an equivalent in-network request, and it can take longer, since the reviewing team may have less familiarity with the specific out-of-network provider.

Plan type matters

How much this affects a person depends heavily on plan structure. Under HMO-style plans, out-of-network care is often not covered at all outside emergencies, so the more relevant question is whether an exception to see an out-of-network provider will be granted in the first place. Under PPO-style plans, out-of-network care is typically covered but at a lower reimbursement level, and prior authorization is commonly still required to get any coverage at that reduced rate. Reviewing how a plan defines its network is usually the first step before assuming authorization rules will match in-network care.

Emergencies are treated differently

Emergency care is generally an exception to out-of-network authorization requirements, since plans aren’t allowed to require prior approval before treating a true emergency. Once a patient is stabilized, though, authorization requirements can resume for any follow-up out-of-network care, which is a distinction that sometimes surprises patients admitted for emergency treatment at an out-of-network facility.

What happens without it

Going out-of-network without the required authorization doesn’t necessarily mean total non-coverage, but it commonly means a higher out-of-pocket share, a flat denial, or a slower review than a routine claim. When a denial does happen, the appeals process is generally the mechanism available to contest it, though appeals for out-of-network denials can be harder to win than in-network ones if the plan concludes an in-network option was reasonably available.

What to weigh

Before assuming a specialist or facility is covered simply because a referral exists, it’s worth confirming both network status and authorization requirements separately, since either one alone can create an unexpected bill. Whether care is covered and whether it’s authorized don’t always have the same answer, and out-of-network care is where that gap tends to show up most.
