An external review is an independent review of a health plan’s decision to deny addiction treatment after the plan has completed its own internal appeal process. Instead of the insurance company making the final decision, an outside review organization evaluates whether the denied service should be covered. External review can be especially relevant when a denial involves medical necessity, the appropriate treatment setting, or level of care.
When can an addiction-treatment denial go to external review?
CMS explains that external review can apply to denials involving medical judgment, including medical necessity, appropriateness, health-care setting, level of care, or effectiveness of a covered benefit. In many cases, you first complete the plan’s internal appeal process and receive a final internal adverse benefit determination.
Some urgent situations may allow an expedited external review at the same time as an expedited internal appeal.
How is external review different from an internal appeal?
An internal appeal asks the health plan to reconsider its own denial. An external review asks an independent organization outside the plan to review the decision.
If the external reviewer overturns a denial that is subject to the federal external-review rules, the health plan is generally bound by that decision and must authorize or pay for the covered service as required.
What types of rehab denials may qualify?
External review may be available when an insurer denies residential treatment, PHP, IOP, detox, or another addiction-treatment service based on a clinical judgment such as medical necessity or level of care. A denial involving an experimental or investigational treatment may also qualify under applicable rules.
Coverage rights depend on the type of health plan, whether state or federal external-review rules apply, and the reason for denial.
Do I always have to finish the internal appeal first?
Usually, yes. CMS explains that a final internal adverse benefit determination commonly comes before external review. However, urgent situations and certain procedural failures can allow earlier access to external review.
Read the denial notice carefully because it should explain the applicable appeal path and deadlines.
How long do I have to request external review?
Deadlines vary by plan and review system. For the HHS-administered federal external-review process, CMS states that a request generally must be filed within four months after receiving the applicable adverse benefit determination or final internal adverse benefit determination. Other state or plan processes can use different timeframes.
Do not rely on a general deadline if your denial notice gives a specific date. Follow the notice that applies to your plan.
Who performs the external review?
An independent review organization or another outside reviewer handles the case. Depending on the plan, the review may follow a state external-review process, a federally approved independent-review process, or the HHS-administered federal process.
The reviewer is separate from the insurer that issued the denial.
What should I submit with the request?
Useful materials can include the final denial notice, the treatment provider’s clinical documentation, the treatment plan, relevant medical records, the insurer’s medical-necessity criteria, and any records that explain why the requested level of care is appropriate.
Under federal claims rules, patients and authorized representatives may be entitled to relevant claim documents without charge. For mental health and substance use disorder claims, plans must also make medical-necessity criteria and reasons for denial available as required by MHPAEA and related rules.
What happens if the external reviewer overturns the denial?
If the reviewer decides the denied service should be covered under the applicable external-review process, the plan generally must follow that decision. The practical result may be authorization of treatment, payment of a previously denied claim, or another coverage action required by the decision.
What if the external review upholds the denial?
Additional options depend on the plan and applicable law. You may be able to contact the relevant state insurance regulator, the U.S. Department of Labor for an ERISA-covered employer plan, or obtain legal advice about other rights or remedies.
How does this connect with an addiction-treatment insurance appeal?
External review is usually one later step in the broader appeal process. Trinity has a separate guide on appealing an insurance denial for residential rehab. For people using private PPO coverage, Trinity also provides a benefits verification option, but verification does not guarantee authorization or final payment.
Frequently asked questions
Is external review the same as a peer-to-peer review?
No. A peer-to-peer review usually involves a clinician from the treatment side speaking with a clinician working for or on behalf of the insurer. External review is performed by an independent organization outside the insurer.
Can a provider request external review for me?
Often, an authorized representative can act for the patient, but the plan’s authorization requirements should be followed.
Can external review be expedited?
Yes, in certain urgent situations where waiting for the standard process could seriously jeopardize health or the ability to regain maximum function.
Does external review guarantee approval?
No. The independent reviewer may uphold or overturn the denial based on the record and applicable coverage rules.
