Man this is a hellscape.

I can quickly see something like this turning in an AI arms race between insurance and the provider with each auto-approving/denying/disputing the other. All the while locking out smaller players because they can't afford the 3rd party disputotron.

tantalor•1h ago
Hate it, thanks
Spivak•1h ago
You would have to leverage the law (if you have one) that involves the state resolving the dispute because otherwise the automated disputes would probably be dropped on the floor. The insurance company has the leverage because they're actually in possession of the money and the contract that gives them stupidly high discretion on how much to pay out.

Doing nothing but flipping the burden, doctors get paid whatever they invoice and insurance have to claw it back would make a lot of this stonewalling bullshit go away. But with an openly corrupt government paid by insurance it'll never happen.

pragmatic•1h ago
Its a terrible business.

The data is a disaster. Turnover is high, errs everywhere. Disputing is the easy part. Hard part is finding the contracts lol.

If someone invoices me, and I don’t pay the full amount in a timely manner, what do you think will happen? Late fees, reports to credit bureaus, collections agencies hounding me, maybe even lawsuits?

If insurance companies underpay, doctors should treat that no differently. Don’t appeal through the insurance company itself. Imagine I go to a store and pay less than the full amount at the register, and then the grocery store appeals to ME to decide whether I actually should have paid the correct amount. It’s absurd.

Doctors should treat the insurance companies like anyone else who owes them money and isn’t paying in full on time.

hn_go_brrrrr•2h ago
I was thinking the same thing. Would it be permissible to bring each underpayment to small claims court as a separate case? If enough doctors did this, it would very quickly be a legal DDoS attack, like we've seen happen with mandatory arbitration.
postflopclarity•2h ago
good luck suing when lawyers cost the doctor 2k/hour and the insurance companies have armies of in house counsel.
gwbas1c•1h ago
Doctors have extensive contracts with insurance companies, and often have employees dedicated to billing. I wouldn't make assumptions here, other than "downcoding" is probably just subtle enough to not be worth it to fight.

I have no problem with it being for profit. The issue is the alignment of interests and the thumb on the scales by government and vested interests. If health insurance worked like car insurance I think we'd be in a better state.

> Find some doctors, nurses, researchers, manufacturers etc etc who will work for no money and we can remove money from the problem.

Not being for profit doesn't mean you don't pay people.

Further, I wonder how the Sixth Amendment works then? So many non-profit people working for... no money?

This "work for no money argument" is so incredibly weak, I had to make sure I quoted the argument so the person wouldn't change it.

philipallstar•35m ago
Eventually everyone works for profit if they get paid. Spending time only is pure profit in money.
iamnothere•17m ago
A reasonable wage or salary isn’t usually considered “profit” in a legal sense. This is why nonprofits can still pay employees. Any money that is left over after costs (including wages/salaries) needs to be reinvested, spent on the organizational mission, or held for future use, not distributed through dividends or other distributions as in a for-profit enterprise.
some_random•40m ago
You're welcome to come up with an alternative system of aligning interests, so far all of the other ones have failed horrifically.

Sure but imagine you hire a landscaper and they send you a $40 invoice for $20 of law cutting and $20 of leaf cleanup. You go look outside and see a ton of leafs so you just send them $20.

That's the insurance companies' stance. The work you performed is this and so our agreed upon rate is this.

bshep•1h ago
but the landscaper has a photo of the clean yard after they finished. They send it to you but you ( as the insurance company) say they need to call a specific time and speak to your 12y/o who is the yard representative of the house.

The 12 y/o say ‘no you stink’ and hangs up. Then you send the landscaper a letter saying ‘sorry your peer to peer was denied’

( I know this is exaggerating a bit and made to sound funny but it mostly works like that in healthcare )

kstrauser•34m ago
But in reality, the landscaper bills you for $100, you say you’re only going to pay $90, and then you write them a check for $31.50.

(That’s because you’re a major, well-known insurer and pay an industry high 35%. The guy who mows the Medicare yard might pay 40 cents on the dollar. The person mowing the Medicaid yard has to file 87 forms to get paid his $6.)

Source: I’ve co-owned doctors offices.

pragmatic•1h ago
Insurers (payers in the industry lingo) simply don’t pay or underpay.

Proving this sucks bc smaller practices have horrible staff turnover, the EMRs are dog shit and the contracts are who knows where and in what format.

Recovery is beyond the scope of most small practices.

Its a nightmare where providers are often shorted millions of dollars and that ends up coming out of the patient’s pocket.

Everyone yammering about upcoding on this thread is blissfully clueless.

kamarg•1h ago
> Recovery is beyond the scope of most small practices.

Seems like a business opportunity. Could probably work very similar to other collections agencies where they either buy the debt for pennies on the dollar or take a percentage of the collected amount.

spiffytech•1h ago
Insurance companies hold tremendous leverage over care providers, up to and including the power to effectively put them out of business on a whim. Care providers don't like picking fights with insurance companies.
kotaKat•2h ago
Ah yes, this is a fight between the practices (sometimes not the doctors!) upcoding their visits and the insurance companies wanting to push back and downcode the visits to what they actually entailed.

Healthcare practices want to maximize revenue and push up the “level” of a doctors visit and they can do it with just adding one or two extra little questionnaires or an extra test or two that you might not pay attention to so they can get an extra several hundred dollars a day for billing higher level cases daily.

polski-g•1h ago
There is immense pressure on insurance companies to lower costs, as they get blamed for the "American health care system". The only one on the side of the payer is the insurance company, they're the only one who wants to keep costs down for the consumer. Given the massive amounts of fraud in government health insurance (medicare) it would of course be prevalent in the private insurance market.

https://www.azcentral.com/story/news/local/arizona-health/20...

vjvjvjvjghv•1h ago
“ they're the only one who wants to keep costs down for the consumer.”

They don’t. They want to increase profits by pushing more and more cost to the patient while squeezing providers. The patient is always the loser in this system. One reason is that most patients don’t even have a choice of insurance because their employer picks the insurance that’s best for the employer.

arealaccount•1h ago
I never understood why insurers get all the flack while the providers get a pass.
cogman10•1h ago
Because the common interaction people have with their insurers is "We are denying this because of <REASON>" which they have to fight to get healthcare.

When a provider rips off an insurer it's invisible to the general public.

Also, incidentally, when people talk about fraud in Medicare/Medicaid, the providers are almost always where that happens (yet that's often not pointed out).

walkabout•1h ago
FWIW I hate most medical billing departments (and hospitals are the worst) about as much as I hate insurance.

They're at least as likely to fuck something up (curiously, always in their favor, not yours) as insurers, from what I've seen. And they're almost as unpleasant to deal with—at least they don't generally keep you on hold for literal hours, but it's still not great.

And one of the ugliest public-facing roles in all of American medicine has to be the insurance-vultures whose job is to hover about emergency rooms pestering very-sick people for their billing information. Fucking gross.

potato3732842•1h ago
Every party at every point in the system is various shades of complicit in fleecing us. That's the magic of the system. It's all divided up in so many ways and so many of the feedback loops touch through the people getting screwed that it's impossible to build a "these guys might not be wholly responsible, but they're responsible enough things will get better if we push them off a cliff or legislate them into poverty or whatever" consensus you need to build to change things

17% of the US GDP is healthcare, now obviously there's a lot of nurses and random courier drivers and all sorts of other stuff in there, but they would all need to take some amount of haircut for us to get fleeced less.

The GDP contribution of slavery was ~13% just preceding the civil war and credible moves (i.e. electing Lincoln) to make them take a haircut caused, you know, the civil war.

There is likely no "clean" way to fix this problem other than a century long frog boiling exercise

daoboy•1h ago
For what it's worth, this sort of gaming works both ways.

Many medical administrations do everything they can to upcode in order to bill for more money.

The whole system is a mess.

Other countries are making efforts to keep things in check though https://www.npr.org/2025/01/04/nx-s1-5246231/potential-fraud.... The US for some reason can’t even address blatant fraud. One example is the stuff insurers do with Medicare Advantage. There is fraud and Congress knows about it but besides some hearings nothing is happening.
jasonlotito•59m ago
It does.

And having lived 10 years in Canada and 10 years in the US and used both their healthcare systems quite a bit, I have seen both sides. Let me just say I moved to the US for healthcare 10 years ago and we do not regret it one bit. The US is easy to point and laugh at, but that just comes from ignorance.

bluGill•1h ago
IT is beyond our control because we have setup a system where the people who are paying don't want to control things.

My boss wants insurance to be expensive - if I could afford it I would be more willing to quit (retire early).

Finding cheaper services isn't in my interest - I'm not paying any bills anyway.

Insurance companies like the complexity because it means I can't understand the system and so I have to use them.

Doctors don't really care as they just have administrators play the game for them. Once in a while they look at the game and say something, but really this is just they don't understand how the game is played (they shouldn't - they are doctors, they should be looking at medical issues not administrative ones).

potato3732842•1h ago
There's an old mechanics saying "if X was covered by insurance it'd cost what Y does" where X is some routine thing (tires/brakes/etc) and Y is autobody or glass services typically covered by insurance.

This proverb seems to also apply to health insurance and the things they do/don't cover.

Putting routine stuff under the purview of insurance is stupid regardless of context. There are other cheaper, faster, simpler and more transparent ways of doing that.

pastor_williams•57m ago
Doctors have also spent a lot of time lobbying to make becoming a doctor harder so that the fewer doctors will be able to command better salaries. It sounds like they are attempting to reverse that and open up more spots for residencies but I imagine that there is a lot of momentum to overcome.
pnathan•1h ago
I wonder how this plays out with Kaiser and other integrated practices.
gwbas1c•1h ago
This doesn't surprise me: The "fee for service" system encourages doctors to perform as many services as they can so they can bill for more. I've certainly had my fair share of tests and procedures where I wonder if the provider was just trying to find something to bill for.

I'm also not surprised that some providers will try to figure out which codes they can use to get the most revenue. ("Hey, if I do procedure A instead of B, I get paid more, so why would I do B?")

That being said, I also wouldn't be surprised if many of these turn into lawsuits, or ultimately push to revise the whole "fee for service" system.

I went to the dentist a couple of weeks ago and had the shortest dental visit I've had. They did the X-rays, then the dental assistant spent five minutes cleaning my teeth and pronounced them good. The dentist came in and looked for about one minute and said they were fine. I was sent on my way.

They billed my insurance for over a thousand dollars.

eigencoder•1h ago
My pediatrician always charges us for an office visit + preventative care when we go in for a preventative care visit. It's obviously to get more $$ from insurance. I feel like this goes both ways...
3D30497420•49m ago
This sort of thing gets to two critical problems of the American system: 1. It is largely designed to make money, not actually help patients. So every step in the healthcare chain that can extract a bit of value will do so, largely to boost profits. 2. Insane complexity with limited transparency. How much will something cost? Hard to tell. Will it be covered? Who knows?

On the opacity, I have one informative anecdote. I had a single blood test done awhile back and no one knew if insurance would cover it, or which of the dozen or so billing codes it involved (taking the sample, delivering the sample, testing the sample, etc.) might be covered. It was an expensive test so I spent days bouncing between the doctor's billing team and the insurance company until the settled answer was: No one knows, do the test and insurance will decide. So I did it and insurance denied covering the doctor-recommended test. The salaries involved for all the billing people (and my time) would have covered the cost of the test. </rant>

hypeatei•26m ago
> No one knows, do the test and insurance will decide

Oh, someone knew but the doctors office wanted to do the expensive thing and get paid (either by you or the insurance)

Not saying the blood test was unnecessary but we have no idea what communication happened between the doctor and insurance company. Did they possibly recommend a less expensive test and the doctor decided that'd make him less money so he went forward anyway?

djoldman•48m ago
We'll never know, but:

I wonder what would happen if we moved the "medically necessary" requirement burden of proof from the doctor/patient to the insurer. So the insurer would be required to pay out a claim regardless of whether the insurer thought it was medically necessary, but their recourse could be to try to claw it back post-payment.

_boffin_•21m ago
Are you talking overnight? If so, that’s an easy predictable outcome.
hypeatei•7m ago
They'd most likely go bankrupt. There is already an incentive for them to spend on medical care due to the Medical Loss Ratio (MLR) which caps their profits on collected premiums.

If you're saying they need to be forced to pay whatever invoice comes to them and start legal battles for each suspect case then yeah... that doesn't seem feasible.

renewiltord•25m ago
People get annoyed at insurers who will deny treatment but most of the time you can just pay it yourself. The government has decided that everyone should pay for health insurance but you'll never be denied care if you pay for it yourself.

So if you think you do require some care, just ask the medical practice whether they accept self-pay and then you can decide if it's worth paying or not. If you think it's not, it's unlikely someone else will if they have to pay on your behalf.

Essentially, place yourself in the role of each participant:

- patient: wants to maximize care, money no object since it isn't theirs

- medical practice: wants to maximize money spent on care

- insurer: wants to minimize money spent on care

Normally, the first two would be happy to collude to charge the third any amount of money since they'd both get what they want. And that is indeed what happens. So you get the natural result that the insurer doesn't want to support certain payments even if they were kind and pure-hearted. That they don't want to when they're neither should then not be a surprise.

You can remove that pressure by turning the interaction into:

- patient: wants to maximize care with minimized cost

- practice: wants to minimize care with maximized cost

The pressures between the two parties are now opposite and you can find the market equilibrium. With this opposition you'll suddenly find that patients start complaining about doctors ordering unnecessary procedures and so on, just like insurers claim in the other model.

You can also work through with the other versions to model where equilibrium will set in and see if it's where it does. Most of the time you don't need to assume any moral valence for the participants. They might as well be machines. It is their roles that determine how they act, not their personalities.
