Residential and level-of-care denials
Behavioral health and substance-use disorder denials often turn on level-of-care decisions, residential vs. partial hospitalization vs. intensive outpatient. Carriers frequently deny residential placement using internal criteria that have been ruled inadequate in landmark litigation, including Wit v. United Behavioral Health.
The rule that controls this: Generally accepted standards of care (ASAM Criteria, LOCUS/CALOCUS) plus MHPAEA parity control level-of-care determinations.

How we approach the appeal
Cite generally accepted standards of care, ASAM Criteria for SUD, LOCUS / CALOCUS for MH, APA practice guidelines. Reference Wit v. United Behavioral Health for the principle that plans must use criteria consistent with generally accepted standards, not internally restrictive ones. Pair with a federal MHPAEA parity argument. Document acute risk factors (suicidality, self-harm history, prior treatment failures) precisely.
