Disclaimer - I consider myself a programmer, but I’ve spent my entire career (8.5 years) programming in health benefits administration.
For the record, the traditional indemnity plan is far from dead in the US (though admittedly much more common for retirees). And HSAs are getting very common among large employers, though enrollments are still fairly low.
Actually it’s a very precisely defined term. You’re confusing yourself by thinking that several separate systems are all part of an overall umbrella called “HMO”, when they’re really unrelated competitors.
Not an HMO. I’m not sure what they exact term would be in this case, probably just “clinic”.
Not an HMO. You’ve covered most of the pertinent points about this system. I quite like them, as you usually get decent access to specialists without needing a referral. I would add that these networks can often be smaller than the other types. However, it’s not uncommon these days for them to be contracted with a POS, creating a kind of hybrid (with names such as “Blue Cross Blue Shield POS (PPO Network)”.
Also not an HMO. There are some important points that you missed:
- There is usually a network involved, and coinsurance and copays will be significantly lower if you use a doctor, hospital, or specialist in-network. Many plans nowadays are “national plans”, which means that they have in-network doctors pretty much everywhere in the US.
- I think that it’s the coinsurance that you’re thinking of with the “most charge more”, but it usually doesn’t have anything to do with the price the doctor charges. Coinsurance percentages are set by your employer when they contract with the plan, and you can negotiate your own if you’re buying coverage directly. Think of it as a sort of deductible. Routine care is often completely covered. Incidentally, most PPOs work this way as well.
- Many (but not all) allow you to visit a specialist without a referral, though usually at a higher copay.
- While traditionally more expensive to purchase than an HMO, it is not uncommon anymore for the reverse to be true. For instance, my POS costs about $1000 out of pocket less a year than the HMO I could have taken.
There are dozens of minor variations (several people mentioned Kaiser), but the basic distinguishing characteristic of a traditional HMO is the gatekeeper. These are doctors who contract with the plan (and no, they are not considered employees of the HMO, they’re still their own businesses). You choose your Primary Care Physician when you enroll in the plan, and they are the one you see for any non-hospital-emergency problem. They treat what they can, and then refer you to a specialist or hospital if you need one. The basic theory behind this is that your primary doctor is perfectly capable of dealing with most problems, and are relatively cheap. If you choose to ignore the PCP’s gatekeeper role and go directly to whomever you want, the HMO will pay nothing.
What the consumer is supposed to get out of giving up their control is the low monthly cost of the coverage, low copays, and no paperwork to file. After several years of rapidly escalating costs and constant pressure from unhappy consumers to loosen their controls, HMOs are sometimes no longer the lowest cost option and have tended to drift away from the “pure” model.
