Concurrent Review Insurance Denial? How to Appeal

A concurrent review denial is uniquely urgent: the insurer is refusing to authorize continued coverage for treatment that is already in progress. Unlike a Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization denial (which happens before care begins) or a retrospective denial (which happens after care ends), a concurrent review denial occurs during your hospitalization or course of treatment — creating immediate pressure to discharge or stop treatment, sometimes against medical advice.

Understanding what concurrent review is, why these denials happen, and how to respond in real time is essential.

What Concurrent Review Is

Concurrent review — also called concurrent authorization or continued stay review — is the insurer's process of monitoring and authorizing continued coverage for ongoing treatment, typically inpatient hospitalization. The insurer's utilization management team periodically reviews whether the patient still meets criteria for the current level of care, and either authorizes additional days of coverage or denies continued stay.

Concurrent review is most common for:

• Inpatient hospital stays (medical and surgical)
• Inpatient psychiatric and substance abuse treatment
• Inpatient rehabilitation (acute rehab facilities)
• Partial hospitalization programs (PHP)
• Skilled nursing facility (SNF) stays
• Long-term acute care hospital (LTACH) stays

When a concurrent review is denied, the insurer is saying it will not pay for care beyond the authorized period — even though the care is already ongoing and your physician has determined continued treatment is medically necessary.

Why Concurrent Review Denials Happen

Level of care criteria not met according to insurer. The most common reason. The insurer's utilization reviewer determined that you no longer meet criteria for the current level of care — for example, that you could safely be discharged to a lower level of care or managed as an outpatient. This determination is made using InterQual or Milliman criteria, often by a nurse reviewer who has never examined you.

Documentation gap. The clinical records sent to the insurer do not adequately demonstrate continued medical necessity for the current level of care. This is sometimes a communication problem between the hospital's utilization management team and the insurer, rather than a genuine clinical disagreement.

Premature discharge pressure. Some insurers use concurrent review denials as leverage to push facilities to discharge patients earlier. The denial is issued before the treating team has determined the patient is ready — creating conflict between the insurer's utilization timeline and the physician's clinical judgment.

Psychiatric and substance abuse treatment denials. These are disproportionately common in concurrent review. Insurers frequently deny continued inpatient psychiatric stays and residential substance abuse treatment, claiming criteria for lower-level care are met. These denials are particularly vulnerable to Mental Health Parity Act challenges.

Skilled nursing facility criteria. Medicare and most commercial plans cover SNF stays only when the patient requires skilled nursing care (not just custodial care). Concurrent review denials often argue the patient has "plateaued" in progress and no longer requires skilled care. Medicare has specific rules about this, and beneficiaries have the right to a fast-track appeal.

Your Legal Rights

The ACA requires coverage of essential health benefits including hospitalization and requires that all denials — including concurrent review denials — be subject to internal appeal and External Independent Review: Complete Guide" class="auto-link">external review.

ERISA requires that employer plan denials be reasoned, written, and supported by the specific plan criteria applied. The plan must give you access to the clinical criteria used in the concurrent review.

The Mental Health Parity and Addiction Equity Act (MHPAEA) prohibits applying stricter utilization management criteria to mental health and substance use disorder admissions than to medical/surgical admissions. If your concurrent review denial involves psychiatric or substance abuse treatment, request a non-quantitative treatment limitation (NQTL) analysis to verify the insurer is applying the same standards it uses for comparable medical admissions.

Medicare fast-track appeals. Medicare beneficiaries facing hospital discharge because of a concurrent review denial have the right to an immediate (same-day) appeal to the Quality Improvement Organization (QIO). Filing this appeal allows you to remain in the hospital without financial liability until the QIO issues its decision — typically within one business day. Request the "Important Message from Medicare" document from the hospital's patient advocate; it explains this right.

PASRR for psychiatric patients. Before discharging a psychiatric patient to a nursing facility, specific federal pre-admission screening requirements apply. If your concurrent review denial involves a psychiatric patient's discharge to a lower level of care, these requirements may affect the discharge plan.

Documentation Checklist

• The concurrent review denial notice (Organization Determination or Adverse Benefit Determination) with the specific criteria cited
• The treating physician's current clinical notes documenting continued medical necessity for the current level of care
• A letter from the attending physician addressing the specific insurer criteria that were cited as not met
• Hospital utilization management team's records showing what documentation was submitted for concurrent review
• Relevant clinical guidelines supporting continued stay at this level of care (e.g., ASAM criteria for substance abuse, APA guidelines for psychiatric hospitalization)
• For Medicare: the "Important Message from Medicare" document and QIO contact information
• For mental health parity cases: documentation of how the insurer applies comparable criteria for medical/surgical admissions

Step-by-Step Appeal Strategy

Step 1: Act immediately. Concurrent review denials have short action windows. Contact the hospital's utilization management or case management team the same day you receive the denial. They should be coordinating with the insurer's medical director.

Step 2: Request an expedited peer-to-peer review. Your attending physician or the hospital's utilization management physician should request an immediate peer-to-peer review with the insurer's medical director. Many concurrent review denials are reversed in peer-to-peer conversations when the treating physician can explain the clinical picture directly.

Step 3: Request an expedited appeal. File an expedited internal appeal the same day. Concurrent review denials involve ongoing medical care and qualify for expedited timelines — typically 24–72 hours. Clearly state that continued inpatient care is medically necessary and that the denial jeopardizes your health.

Step 4: For Medicare patients, invoke QIO rights. If you are a Medicare beneficiary being told you must leave the hospital, request the Important Message from Medicare and file an immediate QIO appeal. You cannot be held financially liable for the additional days while the QIO reviews your case.

Step 5: Cite the applicable clinical criteria. Address the specific criterion the insurer cited as not met. Your physician's notes and a physician letter should directly explain why the patient continues to meet that criterion, or why the insurer's criteria are more restrictive than generally accepted clinical standards.

Step 6: Raise Mental Health Parity if applicable. If the denial involves psychiatric or substance abuse treatment, challenge the insurer to show that it applies the same criteria for comparable medical/surgical continued stays. Request the NQTL comparative analysis.

Step 7: Escalate to external review. If the expedited internal appeal fails, immediately request expedited external review. External reviewers for clinical denials are independent clinicians who evaluate the case on its medical merits without the financial incentives that influence insurer reviewers.
