If employers wanted it, insurers would be happy to offer health plans that fully paid every claim with zero denials. This would be enormously profitable for the insurers because they could run those health plans with minimal work. But instead, most employers are constantly looking for ways to cut employee health benefit costs. This means incentives aren't aligned.
The person at the insurer who denies a claim is not making more money because they denied it. The company as a whole might, but not the person denying it.
There are numerous stakeholders who setup the rules - the government, insurance companies, hospitals, doctors, billers, etc.
All of them profit from the current system, but there is no single stakeholder who decides the overall rules.
Fixing it is another matter. Of course that’s not easy.
Medicare per-capita spending is more than NHS per capita spending, but the NHS covers everyone.
Of course healthcare is denied in any system (in other systems this is triage), but nowhere to the level United Health does it: over 30%, it's on a completely different scale.
Plenty of treatments are denied in other countries. Not to mention most other countries have private insurance layered on top of public and it’s the same issue - private insurers denying a treatment through their own process.
If US insurers are guilty of murder than most of the worlds insurers are too.
In the US it’s insurance companies (or the government through Medicare or Medicaid) but in the UK it’s NICE, in Canada it’s CADTH and the provincial health authorities.
Since there are finite resources spent on healthcare, trade offs are made all the time. If spending $10M on treatment A saved 10,000 lives and $10M on treatment B saves 1,000 lives, then treatment A gets funded and treatment B doesn’t.
The difference is that patients in the US have an up close and personal experience with denial.
In Canada and the UK they don’t because doctors knows what is covered and what isn’t so never bring up life saving options if they aren’t paid for.
In rare circumstances like cystic fibrosis in the UK, patients become aware that they are being denied a life saving drug and protest, but generally it’s pretty rare because patients just don’t know the option exists.
