An out-of-network copayment is a fixed dollar amount you pay for a covered service from a provider who isn't in your plan's network. It's typically higher than the copayment you'd pay for the same service from an in-network provider.
Not all plans use copayments for out-of-network care; many use coinsurance (a percentage) instead. But when a plan does have out-of-network copays, they're noticeably more expensive. For example, your plan might charge a $30 copay for an in-network primary care visit but $75 for the same visit out-of-network.
Like out-of-network coinsurance, copayments for out-of-network care come with additional financial risks. The copay only covers a portion of the allowed amount; if the out-of-network provider charges more than what your plan considers reasonable, you could be balance billed for the rest. And out-of-network copays may not count toward your plan's out-of-pocket maximum.
HMO and EPO plans generally don't cover non-emergency out-of-network services at all, so there would be no copay; you'd owe the full amount. PPO and POS plans are more likely to have out-of-network copay or coinsurance structures.
Before seeing an out-of-network provider by choice, always call your insurance company to understand what you'll owe. The copay alone doesn't tell the full story; ask about balance billing exposure and whether the costs count toward your maximum.
Not necessarily. On top of the copay, the provider may balance bill you for the difference between their charge and your plan's allowed amount. The copay is your share of the plan's covered amount; any excess is separate.
