Weight loss treatment coverage in California
Which document decides your case in California depends on who pays your claims. This page routes you to the one that governs your plan: the state program, a plan measured against the state benchmark, or the appeal route once a plan has said no.

Start by finding out which document governs your plan
Everything else follows from it. A state program publishes its own rules. A marketplace plan is measured against a state benchmark. An employer plan that pays claims out of the employer's own funds sets its own rules, and no state rule reaches it.
Why this site does not answer with one word
A coverage answer is only true inside a scope: one payer, one drug or benefit, one indication, one date. The same molecule can be covered for diabetes and excluded for obesity by the same program on the same day, and a page that ignores that difference is wrong for half its readers. Every record on this site carries all four, which is why the pages are organised by who pays rather than by what you want.
The questions California does not decide
Four answers are the same in every jurisdiction, so they live on one page each rather than on fifty. Whether a state rule reaches your plan at all is the first: an employer plan that pays its own claims follows its plan document, and nothing on the California pages describes it. The body that hears an appeal is the second, because the forum is set by who pays rather than by where you live. Then what a prior authorization request has to contain, and what the treatment costs when no plan is paying.
Common questions
Does this site say whether my own plan in California covers a weight loss drug?
No. It says what a named, dated policy document requires. The same insurer sells many plans, and an employer that pays claims from its own funds sets its own rules regardless of any state document, so your plan documents are the only thing that decides your case.
Which plans do the California pages describe?
The pages describe the plan classes a state document actually reaches: Medi-Cal, California's Medicaid program and plans measured against the state benchmark. A self-funded employer plan is not one of them, because state insurance rules are preempted for those plans.
Where does an appeal go in California?
California runs its own external review program. A reader who has finished the plan's internal appeal asks that program for an independent review.
