How to appeal a weight loss treatment denial in California
A denial is a step in a process, not the end of one. In California the route runs in a fixed order: an appeal to the plan first, then an independent review once the plan has given its final answer. This page sets out that order and who hears each stage.

Start here: what was denied?
A medication
72 hours
for the plan to decide a formulary exception, or 24 hours when the circumstances are exigent. This is a different and much shorter clock than the grievance rule below.
A procedure, or care already given
30 days
for the plan to answer its own appeal. The independent review opens after that answer, on its own clock.
Once the plan gives its final answer you have 6 months to ask for an independent review, counted from any of the qualifying periods or events under Health and Safety Code section 1374.30, subdivision (j). That is the deadline you cannot get back.
Both figures come from California's own governing sections. Your notice states the limit for your case, and it is the document that decides it.
One check first: which kind of plan you have. No state rule reaches a self-funded employer plan, which is most job-based coverage, and a deadline taken from this page would be the wrong one.
The order the steps run in
Step one
Read the notice, not a summary of it
The notice you received is the document that governs your case. It names the reason for the denial, the deadline for challenging it, and where to send the challenge. Every later step depends on those three things, and no general page can replace them.
Step two
Appeal to the plan
The first challenge goes to the plan that issued the denial. It is a request for the plan to look again, and it is the step that has to be finished before anyone independent will look at the case.
Step three
Ask for an independent review
California runs its own external review program. A reader who has finished the plan's internal appeal asks that program for an independent review.
The clock
Every limit below was read from California's own governing sections, and the middle column is the one to check against your notice: two states with the same number and a different starting event do not have the same deadline.

|---|---|---|---|
| Ask the plan to look againThe internal appeal. This is the step that has to finish first. | 180 calendar daysWhat this limit depends onCalifornia's own Knox-Keene Act sets no deadline for filing the grievance itself. The 180 days is the federal floor for plans the federal claims rules reach, which is most job based and marketplace coverage.

You have to take the plan's grievance process first, but the plan cannot run the clock forever: section 1374.30 subdivision (j)(3) says you shall not be required to participate for more than 30 days, and section 1368 says the same thing from the department's side. After that you may go to the department whether or not the plan has answered.
If a medication was denied rather than a procedure
California sends this one to federal law by section number, which is why it is the clearest of the four. Section 1368.01 subdivision (c) says a plan covering outpatient prescription drugs shall comply with subdivision (c) of section 156.122 of Title 45 of the Code of Federal Regulations, and both the 30 day grievance rule and the three day expedited rule are written "except as provided in subdivision (c)". So for a denied medication the grievance clock is the wrong one to count. It does not reach every plan: the federal exception rule governs plans that must cover essential health benefits, so a self funded employer plan may run its own process instead. Read your plan documents before taking this clock.
- A standard request
- 72 hours
- From the plan's receipt of the exception request. California's own statute points at this rule by section number, so the 72 hours is the deadline a denied medication runs on rather than the 30 day grievance rule.
- 45 C.F.R. § 156.122(c)(1)(ii)
- When the circumstances are exigent
- 24 hours
- From the plan's receipt of the exception request. 24 hours where the circumstances are exigent. This is the shortest deadline anywhere on this site, and it is the one a reader denied a medication most needs to know.
- 45 C.F.R. § 156.122(c)(2)(iii)
An independent review costs you nothing in California. The statute is explicit that an enrollee pays no application or processing fees of any kind, and the Insurance Code says the same for a policy holder. Cost is a common reason people do not appeal, so it is worth knowing there is none.
Where the request goes, and who decides it
California Department of Managed Health Care, Help Center. The department contracts the review organizations and the statute requires them to be independent of any health care service plan doing business in California. You do not choose the reviewer and neither does your plan.
Both California Independent Medical Review Systems reach insurance the state regulates: a health care service plan under the Knox-Keene Act, or an insurance policy under the Insurance Code. Neither reaches a self funded employer plan, where the employer pays claims from its own funds and federal law governs the appeal instead. That is most people with job based coverage, so read which kind of plan you have before you take a deadline from this page. Medi-Cal is a third route again, with its own forum and its own clock, set out below.
What an external review is and what it can decide covers the step itself: who the reviewer has to be, what happens to the plan when they disagree with it, and how California's windows compare with the other published jurisdictions.
California publishes no standard form for this request, so the request goes in the way the forum above directs.
If the denial came from Medi-Cal
The Medi-Cal route is a different forum on a different clock, and the order matters. If the denial came from a Medi-Cal managed care plan, California section 10951 subdivision (b)(1) requires you to appeal to that plan FIRST, and then gives you 120 calendar days from the day the plan upholds its decision, or from the day your appeal is deemed exhausted, to ask for the state hearing. Filing in the wrong order is a common way to lose a right you had.
Where a fair hearing goes, how long you have, and keeping benefits meanwhile
- How long you have
- 90 days
- From the order or action complained of. The 90 days is the general rule under section 10951 subdivision (a)(1). Subdivision (a)(2) allows a late request for good cause and bars one filed more than 180 days after the action. For a Medi-Cal managed care denial the plan's own appeal comes first and the window is then 120 calendar days from its notice.
Keeping benefits while you argue
There is no number of days here, and that is the point: benefits keep running during the hearing only if the hearing is requested BEFORE the date of action on your notice. Find that date first, because it is the one deadline on this page that decides whether you keep coverage while you argue.
42 C.F.R. § 431.230(a)
You can also read what the published record shows about weight loss drugs and Medi-Cal, which is useful background for an appeal even though it is not a rule.
What an appeal file usually contains
An appeal is a documents exercise. The plan denied a request against written criteria, so the reply that works is the one that shows the criteria being met, in the plan's own terms, with records from the people who treated you. The prescriber writes it; your job is usually to make sure nothing is missing.
- The denial notice itself, including any reference or case number on it.
- The criteria the plan applied, which the notice or the plan documents name.
- The prescriber's letter, written against those criteria rather than in general terms.
- The records that evidence each requirement the criteria list.
What a plan requires varies by plan, so treat this as the shape of a file rather than a checklist for yours. Where a plan's own criteria are published, the page for that plan type quotes them.
Which rule reaches your plan
The appeal route above is the one that applies when a state or federal rule reaches your plan. If your employer pays claims out of its own funds, the plan document sets the rules and the internal appeal is run under federal plan rules instead. Reading what the benchmark plans cover, California included is a fast way to see whether a state document reaches you at all.
Common questions
Can I go straight to an independent review?
Usually not. An external review normally starts only after the plan has given its final answer on an internal appeal, and filing out of order can cost you the review. The exception is an urgent case, where the two can run at the same time. Your notice says which applies.
How long do I have?
Read the notice you received. It sets the clock for your case and it is the authority, not this page. Covered Weight does not publish a deadline for a jurisdiction until it has read the governing document and can quote it, because a wrong deadline here is a right you cannot get back.
Who decides the external review?
California runs its own external review program. A reader who has finished the plan's internal appeal asks that program for an independent review.
Is the appeal different under Medi-Cal?
Yes. A state program runs its own appeal and a fair hearing, on its own clock and in its own forum, and the order is not the same as it is for a commercial plan. Filing in the wrong forum is a common way to lose the right, so read the notice from the program rather than assuming the commercial route applies.
