What is the difference between a grievance and an appeal?
A grievance is a complaint about anything other than a denial. An appeal challenges the denial itself. Filing the wrong one can cost the deadline, because an appeal must be requested within 60 calendar days of the denial notice while a grievance has no such clock.
A thin envelope lands on a kitchen table and sits there, because it looks like a bill. It is a denial. The clock printed on it has been running since the day it was typed. Two ways to complain sit in that rulebook, and only one of them can get the care back.

What counts as a denial you can appeal?#
Seven things count. A denied or limited service is one. A service already approved and then cut is another, and so is a refused payment. Care that did not arrive on time counts.
So does a plan that missed its own deadline on your grievance or appeal. So does a refusal to let you get care outside the network when your rural county has only one plan. The seventh is a bill you asked to dispute and were told no. Each one opens the appeal route, and each one has a clock.
Adverse benefit determination is the legal name, and federal rules spell out all seven triggers rather than leaving any of it to judgment. That matters. Several of the seven do not feel like denials when they land on your kitchen table.
Take a home aide who came four days a week and now comes two, and nobody sent a refusal. The hours simply changed on the page. That is a cut service under the rule.
The first item on the list is the one that gets recognised. Someone asked for a wheelchair, or a scan, and a person in an office answered no. That is the shape everybody pictures.
Six others arrive quietly, with no moment of refusal and no word that sounds like a denial. Those are the ones that are easy to leave unappealed.
There is a test that beats memorising a list. Ask one question. Did what happened change your care or your money? If it did, the appeal lane is open.
What is a grievance, and what is it not?#
A grievance covers dissatisfaction about any matter other than a denial. A rude aide. An hour on hold. A phone nobody answers. A right that was ignored in a room where you sat and waited. The rule defines it by what it excludes.
Put the two definitions side by side and the design shows itself. The appeal lane comes first, with a closed list. The grievance lane gets the remainder.
Hold on to that order, because it does the sorting for you. You never decide what a grievance is by asking whether your complaint feels serious enough. Check the seven triggers first. Nothing fits? Then it is a grievance.
Quality of care sits here, which surprises people. A rushed appointment. A home visit four hours late. A man left in a chair by the wall for a morning. Real, worth reporting, and not one of them is a denial.
Neither lane outranks the other. A grievance is not a lesser appeal. Think of it as a smoke alarm rather than a fire hose. Each is built for a different emergency, and the plan still has to answer both of them.
How long do you have to file each one?#
Sixty calendar days is the number that governs everything else. An appeal must be requested within 60 calendar days of the date on the denial notice. A grievance carries no filing deadline at all. Sixty days is two months to find the letter, read it, and act.
Miss that one and the rest stops mattering. Those are calendar days, not working days, so weekends count and holidays count. The clock starts from the date printed on the page, not the day the envelope reached the house.
Days lost to an envelope that looks like junk come straight out of the sixty. The clock does not pause for the post.
Answering clocks differ by type:
- A grievance may take up to 90 calendar days.
- A standard appeal must be resolved within 30 calendar days.
- An expedited appeal must be resolved within 72 hours.
Thirty days against ninety is the whole point. The lane that can restore care moves three times faster than the lane that cannot.
Look at the shape of that. The complaint with no filing deadline gets the longest answer window. The one with the tightest deadline gets the fastest answer. Urgency sits where the stakes sit.
You can file. So can a doctor, or a representative, with your written consent. Arrange the consent early. The week a denial arrives is the wrong week to be hunting for a signature.
Who decides your appeal inside the plan?#
Someone who had no hand in the first decision. The rule bars anyone involved in a previous level of review. It bars their subordinates too. Where the appeal turns on medical necessity, the decider must hold clinical expertise in treating the condition.
The subordinate clause is the clever part. Without it, a plan could hand the file to a junior colleague at the next desk. Same room. Same manager. A new signature on the same answer. Think of it as a second opinion the rule insists on, taken from someone who did not write the first one.
The expertise requirement is narrower than it looks at first glance. It attaches to medical necessity appeals, to a refused expedited appeal, and to anything clinical. It does not attach to every complaint you might file.
Here is the part worth knowing. The decider must consider everything you submit, whether or not it was considered the first time. New paper is allowed.
So the letter nobody asked for the first time can go in. A doctor writes a page. Somebody is obliged to read it. That is not a courtesy, it is the rule.
What happens after the plan says no again?#
A state fair hearing opens. Once the plan upholds its denial, you get 90 to 120 calendar days to ask for one, with each state setting its own figure inside those federal limits. Ninety days is the floor no state may go below. A judge who does not work for the plan hears the case.
Everything before that happened inside one company. Even the fresh reviewer sits under the same roof, on the same payroll, reading the same screen. A judge works the way a referee works, standing outside both teams and paid by neither of them.
A second door opens early. If the plan misses its own notice and timing requirements, you are treated as having exhausted the appeal and may go straight to the hearing.
That changes what silence means. A plan that goes quiet past its deadline has not built a wall. It has opened a door.
A hearing can be lost without ever being heard, when the days run out or nobody says the next step exists. I did not check any individual state’s figure, so treat 90 days as the floor and look up your own.
Does an automated denial change your appeal rights?#
No. Nothing in the grievance and appeal rules turns on whether a machine helped produce the denial. The same seven triggers apply. The same 60 day clock runs. The same requirement stands that a person holding the right expertise decides the appeal, whatever produced the first answer.
These rules were written before anyone argued about algorithms in coverage. They never mention automation. That silence gets read two ways, and one reading is wrong.
One wrong reading is that an automated denial sits outside the system. It does not. The rulebook attaches your right to what happened to you, never to how the plan reached its answer inside its own building.
Federal advisers put it plainly. In recommendation 2.1 of its June 2026 report to Congress, the Medicaid and Children’s Health Insurance Program Payment and Access Commission asked for guidance stating that all existing regulatory requirements related to adverse determinations apply whether or not automation is used. A recommendation, not law. It exists because the point is being missed.
That same commission recorded something else worth holding next to it. Stakeholders described human oversight as a necessary safeguard, and plans, vendors and states reported that they already have such policies for adverse decisions. Reported is the operative word. Nobody counted.
So the route does not change. You do not have to prove what software was involved. How a decision was made and whether it was right are two questions, and only the second one is yours to raise here.
Which one should you file first?#
Start with the lane the rule assigns. Was a service denied, reduced, stopped or left unpaid? File the appeal. Only the appeal holds the 60 day right and leads to a hearing. Save the grievance for everything else, and file both where both apply.
Filing both can be correct, because a late, rude, badly explained denial is genuinely two separate problems arriving inside one envelope. The denial belongs in the appeal. The handling belongs in the grievance. Neither weakens the other.
Order matters because only one clock expires. Sixty days for the appeal. None for the grievance. So the appeal goes first and the grievance can follow at any pace.
Why does this trip people? Because the plain meanings run backwards. Appeal sounds formal and severe. Grievance sounds like the everyday word for a complaint. In this rulebook the ordinary sounding word is the weaker tool.
The complaint system is built and run by the organisation being complained about, and the rule requires it to have one. Reading the rule yourself is how a family finds the part nobody points them toward, and it matters most for the people with least room to absorb mistakes.
A letter gets kept because it looks like nothing, and that is how a week of the sixty disappears without anybody deciding to lose it. A caregiver who opens every thin envelope the day it lands has a small habit and a real one. It is the kind of supervision a person can actually perform without a law degree.
How both lanes sit inside the wider denial picture is in Medicaid managed care denials.
The printed text of the Code of Federal Regulations (CFR) is free to read at section 438.400, the definitions, and the commission’s own report sits on its public site. Both take a minute to search.
