What is the difference between a statute, a rule and guidance?
A statute is written by Congress, a rule by an agency after public comment, and guidance is the agency explaining itself. Statutes and rules bind. Guidance usually does not, but under the Medicare Act a policy statement can still set a binding standard, so the label never settles it.
Someone hands you a page from a Medicare manual. The rule is right there, apparently. It might be. The page might also carry no legal force at all, and nothing printed on it will tell you which.
Someone is weighing whether a denial is worth fighting. Someone else has a plan policy page open at midnight, apparently settling the matter. A third holds a letter quoting a manual and no idea whether a manual counts. One test serves all three, and it takes about a minute.
Nothing on the page tells you which kind it is. There is no stamp in the corner. No line at the top saying this one binds and this one does not. The header looks official either way. The typeface is the same. The seal at the top, if there is one, is the same seal.
A page that decides your appeal and a page that only describes one arrive looking like each other. The difference is not printed anywhere on them. You work it out from where the page came from and how it was made. That is what the rest of this is for. It starts with where each kind is made.

What are the three kinds of document?#
Three, from three different rooms. Congress writes statutes. An agency writes regulations to carry a statute out, after publishing a draft and taking public comment from anyone who sends one. Then the agency writes everything else that lands on your desk.
That third pile is enormous. Manuals. Policy pages. Answers to common questions. Letters to the contractors who handle claims.
Most people land in the third pile first. It is the easiest of the three to read, because it was written to explain rather than to survive a lawsuit.
Readability is the trap. The clearest page in the stack often has the least weight behind it. A reader with no reason to suspect otherwise takes the clear page as the answer and stops there.
The wider rulebook covers where each kind sits on the shelf. This page is about which one decides.
Which one actually binds?#
Statutes bind. Final regulations bind. Guidance usually does not. That is the ordinary answer and it holds most of the time, whatever paper is in your hand.
Now the part that makes Medicare its own country. The Medicare Act carries a rulemaking requirement that reaches further than the general one.
Its own words cover any rule, requirement, or other statement of policy that establishes or changes a substantive legal standard. The subject matter is named too. The scope of benefits. The payment for services. Who is eligible.
Read that list again. A statement of policy sits inside it.
So the Medicare Act contemplates that a policy statement can establish a binding standard. Elsewhere in federal law the same words work the other way. That is why the bottom of the scale is a range and not a zero. The letterhead on the page tells you nothing about the money.
Why does the label on a document not settle it?#
The test asks what the page does. Not what it is called. An agency can title something a manual update and still have written a rule.
Under general administrative law the labels do the work. A substantive rule carries the force of law. An interpretive rule or a policy statement advises the public what the agency thinks. Those two sort themselves.
Medicare does not sort that way. The statute groups policy statements with rules and requirements. Then it asks one functional question about all three.
Does this establish or change a substantive legal standard about benefits, payment, or who qualifies?
Like a note from a doctor and a prescription from the same doctor, one explains and one instructs. Only one of them the pharmacy will act on. The handwriting looks identical.
So stop reading the header. Read the effect. Does this page change what you are entitled to, what gets paid, or who qualifies? If it does, the label is where the question starts rather than where it ends.
What did the Supreme Court say about that phrase?#
The Court took the phrase apart in 2019, in a case about hospital money. That year is worth holding on to. The reasoning matters more than the outcome, and it fits on one page.
Government lawyers argued that the Medicare Act tracked ordinary administrative law. On that reading, a policy counting as interpretive elsewhere needed no public comment.
The Court disagreed. Its first reason was textual. The Medicare Act contemplates that policy statements can establish or change a substantive legal standard. Under the general statute, policy statements sit with interpretive rules and are not substantive by definition. Two books. Two meanings. One phrase.
Then the sentence worth keeping. The opinion notes that the phrase does not seem to appear anywhere else in the entire United States Code.
One phrase. One statute. One programme. Every instinct carried in from ordinary administrative law arrives at the wrong answer, and that is why. The government lost. The policy it had adopted without public comment was struck down.
Is a local coverage determination binding on you?#
No. That answer is more dangerous than a yes.
A local coverage determination is a policy set by the contractor handling claims in your region. It is a paper written by people you will never meet. The appeal rules say plainly that judges and the Council are not bound by it.
Then, in the same breath, the same rules say those decision makers give the policies substantial deference when they apply. A judge who declines to follow one must put the reasons in writing.
Picture what you are walking into. Not a rule that settles the day against you. Not a suggestion anyone waves away. Something in between, sitting on the table before you arrive, which has to be argued down.
Between not binding and not ignorable sits most of the work in an appeal. A flat no hides that gap completely.
Is a national coverage determination different?#
Completely. The two names sit one word apart and the force runs opposite.
A national coverage determination binds. The regulation says a judge may not disregard the page, set it aside, or otherwise review it. That leaves two openings and no more.
Does it apply to your claim at all? Was it applied correctly to the facts in your file? Both are real questions worth an hour of anyone’s day. Neither one is an argument that the policy itself is wrong.
Four differences the names hide:
- Binding. National yes, local no.
- Setting aside. National never, local with reasons.
- Weight. National total, local deference.
- Challenging it. Part 426, either way.
Only the last line is shared. On every other question the two run opposite, which is a great deal of difference for one word.
Telling somebody a national determination merely gets deference sends them into a hearing to make an argument they cannot win. That is what treating the two as one thing costs a person who trusted the advice.
Which one do you cite when you appeal?#
Reach for the heaviest paper that says what you need. Then stop.
Statute first, if it reaches your situation. Then the final regulation. Then the manual page, worth citing only when nothing above it helps, and worth naming as a manual page when you do.
One more door, and almost nothing written for beneficiaries mentions it. The validity of a coverage policy cannot be argued inside your claim appeal. A separate procedure exists for that argument, aimed at the policy rather than your claim. Two doors. Two questions. Months lost if you pick the wrong one.
Think of it like a builder’s merchant. You do not cart the whole yard to the job. You take the one beam that holds the roof, and you take it from the strongest pile that has one.
A parent writing an appeal at the kitchen table on a Sunday night can do all of this. Name what the page is. Ask what it changes. Cite the heaviest thing that helps. The five parts tell you where to look, and the letter itself tells you where to start.
