Insurance Appeals by Condition

Step-therapy requirements and nutritional counseling exclusions for eating disorder treatment are common non-quantitative treatment limitation issues under MHPAEA. Denials typically involve residential, PHP, or IOP levels of care and turn on whether the plan applies the same criteria it uses for comparable medical/surgical benefits.

Insurers frequently deny IOP and residential substance use disorder treatment on medical-necessity or benefit-maximum grounds. Where a plan covers comparable medical/surgical care without the same restriction, that asymmetry is the core of an MHPAEA parity appeal.

Applied Behavior Analysis (ABA) therapy denials often cite medical necessity or plan exclusions, and some states impose their own autism coverage mandates that layer on top of federal parity protections. Plan type — fully-insured versus self-funded ERISA — determines which framework governs the appeal.

Intensive outpatient (IOP) and partial hospitalization (PHP) denials are among the most common behavioral health parity disputes, frequently tied to step-therapy or prior-authorization requirements not applied to comparable medical/surgical levels of care.

Depression treatment denials — whether outpatient visit limits, medication management, or higher levels of care — are evaluated the same way as any other behavioral health NQTL dispute: compare the plan's restriction on mental health benefits to what it applies for analogous medical/surgical care.

Anxiety disorder denials most often involve visit-limit caps or prior-authorization requirements for outpatient therapy. The MHPAEA parity framework applies to commercial and ERISA plans and turns on whether the same limitation applies to comparable medical/surgical benefits.

PTSD treatment denials frequently involve prior authorization for specialized therapy modalities or higher levels of care. As with other behavioral health conditions, the parity question is whether the plan's restriction is applied no more strictly than for comparable medical/surgical benefits.

OCD treatment, including intensive outpatient programs for exposure and response prevention therapy, is sometimes denied under step-therapy or medical-necessity criteria that are not applied to comparable medical/surgical programs — a pattern the MHPAEA parity framework is designed to address.

Bipolar disorder denials can involve outpatient visit limits, medication-related prior authorization, or denial of higher levels of care during an acute episode. The same MHPAEA comparative-analysis approach used across behavioral health denials applies here.
