Out-of-Network Rehab Costs

Key takeaway

An out-of-network provider has no contract with your plan, so you usually pay more when that care is covered. Balance billing is the gap between the billed charge and the allowed amount, and it often does not count toward the out-of-pocket limit. Parity compares benefit classes. It does not cap that gap. No rehab price is printed here.

The program that can take you has no contract with your plan, and you are afraid the bill will arrive after you are already there. That fear is about money, and the words for it are specific. Out-of-network means the program has not contracted with your plan. The Uniform Glossary says you will usually pay more to see that provider if the plan covers out-of-network services at all, and that the policy explains what those costs may be. Some plans do not cover out-of-network behavioral health except in an emergency.

If you have trouble breathing, a seizure, chest pain, or a possible overdose, call 911. For a mental health crisis, call or text 988. A billing argument is not emergency care.

The allowed amount, and the part that can stick

The allowed amount is the maximum the plan will pay for a covered service. Plans also call it an eligible expense, a payment allowance, or a negotiated rate. Balance billing is the provider's bill for what remains, the difference between the actual billed amount and the allowed amount. The glossary's own example is a $200 charge, a $110 allowed amount, and a $90 balance. Those dollars define the term. They are not what a detox unit, a residential stay, or a counseling hour costs.

Balance billing happens most often with an out-of-network provider. A network provider may not bill you for covered services. "In network for medical care" is not the same sentence as "in network for this residential program." Ask the plan to check the program, not the hospital system next door. Use benefit verification to separate a covered benefit from a network hit.

Your out-of-pocket limit is easy to misunderstand here. That limit never includes the premium, balance-billed charges, or care the plan does not cover. Some plans do not count out-of-network payments, copays, deductibles, or coinsurance toward it. Once you meet the limit, the plan usually pays 100 percent of the allowed amount. A provider can still pursue the amount above the allowed amount if balance billing is permitted. A ceiling on the allowed portion is not a ceiling on the invoice.

Parity compares classes of benefits

CMS applies the parity test separately to six classifications: inpatient in-network, inpatient out-of-network, outpatient in-network, outpatient out-of-network, emergency, and prescription drugs. If a plan covers medical or surgical benefits in a classification, and it covers mental health or substance use benefits at all, it must provide those benefits in that classification too. How a plan sets out-of-network reimbursement is one of the non-quantitative limits CMS names. The processes for substance use care cannot be more restrictive than the predominant processes for medical care in the same class.

That rule can matter if a plan pays out-of-network medical care and refuses out-of-network substance use care in the same classification. It does not say the plan must pay the provider's sticker price. Visit limits, prior authorization, and network composition are spelled out in parity rules. Deductibles and Marketplace essential health benefits are in what insurance pays. Neither conversation is a quote from your plan.

Where the surprise-billing ban stops

For people in group health plans and in group or individual health insurance, CMS describes the No Surprises Act's balance-billing limits in three situations. One is emergency services at a hospital emergency department or an independent freestanding emergency department, including stabilization and, unless certain conditions are met, post-stabilization care. Another is non-emergency items from an out-of-network provider as part of a visit to an in-network hospital, hospital outpatient department, critical access hospital, or ambulatory surgical center. The third is air ambulance from an out-of-network air ambulance provider. A provider that never furnishes services in connection with a visit to those facilities would not furnish items that fall inside the balance-billing prohibitions in the emergency and non-emergency facility rules.

A residential or outpatient addiction program that is not one of those facilities is not swept in by the facility list. That is not a prediction that you will be balance billed, and it is not a promise that you are protected. The federal ban is about settings. State law can restrict bills the federal rules do not. Medicare and Medicaid sit outside the group-plan description CMS gives for these protections. CMS says its FAQ is a general summary and points readers to the full rules.

A different duty under the same act is a good-faith estimate of expected charges for uninsured or self-pay patients, including in settings beyond that facility list. An estimate is not a ban on the charge, and it is not an insurance payment. If you are uninsured, public-funding questions are on rehab cost without insurance and paying for rehab without insurance. Those pages still do not invent a cash price.

Ask before you travel

Ask the plan for the allowed amount it would use, whether out-of-network cost sharing counts toward the deductible and the out-of-pocket limit, and whether preauthorization is required. The glossary says preauthorization is not a promise of payment. Ask the program whether it will bill you for any amount the plan does not allow, and get that answer in writing before you travel. If the only answer is "insurance will cover it," you do not yet know whether you are in network.

We check your benefits before you commit. That check reports what the carrier says. It does not order a program to accept the allowed amount as payment in full. A denied claim goes to insurance appeals.

Common Questions

What is balance billing, in the glossary's words?

The Uniform Glossary says balance billing is when a provider bills you for the balance the plan does not cover, the difference between the billed amount and the allowed amount. Its illustration uses a $200 charge and a $110 allowed amount, leaving $90. Those figures teach the definition. They are not a rehab rate. The glossary says this happens most often with an out-of-network provider, and that a network provider may not bill you for covered services.

Does my out-of-pocket limit catch a balance bill?

The glossary says the out-of-pocket limit never includes your premium, balance-billed charges, or health care the plan does not cover. It also says some plans do not count out-of-network payments toward the limit. After you hit the limit, the plan usually pays 100 percent of the allowed amount, not 100 percent of whatever the provider charged. Read your Summary of Benefits before you assume a ceiling.

Does parity law force the plan to pay an out-of-network rehab bill in full?

No. CMS says that if a plan covers substance use benefits, it must offer them in each classification where it offers medical and surgical benefits, including inpatient and outpatient out-of-network care. Out-of-network reimbursement methods are a non-quantitative limit that has to be comparable. Comparable is not the same as paying the provider's full charge. A written denial can be appealed.

Does the No Surprises Act ban balance bills from every rehab?

No. CMS explains that the ban applies to emergency services at a hospital emergency department or an independent freestanding emergency department, to certain non-emergency services from an out-of-network provider during a visit to an in-network hospital, hospital outpatient department, critical access hospital, or ambulatory surgical center, and to out-of-network air ambulance. A provider that never furnishes care in connection with those facility visits is outside that ban. State law can be stricter. Read the letter for your building.

Who can tell me the number for this program?

The plan, for the allowed amount and your cost sharing, and the program, for what it will bill above that amount. We check your benefits before you commit. That check is not a promise the program will write off a balance. If the plan denies the claim, use the appeals steps. Do not sign travel against a verbal promise you cannot restate.
