Maybe it's restriction that feels like the only controllable thing. Maybe it's binges that arrive like weather, or the purging that started as "just this once," or a relationship with exercise that stopped being about health a while ago. Maybe you're the parent watching a kid disappear a meal at a time. Eating disorders thrive on the same lie at every size and presentation: it's not bad enough to count. If food and body are running your days, it counts.
The short answer: eating disorder treatment is organized in levels of care, and knowing the map changes everything — including what your insurance must pay for. From lightest to most intensive: outpatient (weekly therapist + dietitian) → IOP (intensive outpatient, ~3 hrs/day, several days/week) → PHP (day treatment) → residential → inpatient medical. California parity law requires state-regulated plans to cover the level that's medically necessary — not the cheapest one.¹
Who belongs where — and the medical gate
Weekly outpatient fits when you're medically stable and functioning: an eating-disorder-experienced therapist (CBT-E and FBT are the evidence leaders; for teens, family-based treatment is first-line²) plus ideally a dietitian and a monitoring physician. Step up when outpatient isn't holding — behaviors accelerating, medical flags, meals impossible without support. One thing that is not negotiable: a medical check comes first. Eating disorders are the deadliest psychiatric illnesses, and dangerous complications hide behind "but the labs look normal" and normal weights alike. A PCP visit this week, honest about behaviors, is step one.
Making insurance pay for the right level
The classic denial is "step down to outpatient" while your treatment team says otherwise. Your levers: California's SB 855 parity law (plans must use nonprofit clinical criteria for level-of-care decisions¹), the appeal-and-IMR machinery → — eating-disorder level-of-care denials are frequently overturned at Independent Medical Review — and your team's documentation. Ask any program's admissions office: "Will you run the insurance authorization and appeal if needed?" Good ones do it daily.
The free layer
NEDA is gone — the old hotline shut down; the current navigator is the National Alliance for Eating Disorders: 1-866-662-1235 (clinician-answered, weekdays) with free virtual support groups.³ Medi-Cal covers eating disorder treatment → including specialty levels through county systems. Parents: FBT puts you on the treatment team, not in the waiting room — ask for it by name.
