Understanding Health Insurance: A Health Plan is a Contract [US, healthcare, Patreon]
Dec. 8th, 2025 07:42 am- Introduction
- A Health Plan is a Contract – You are here
Health Insurance is a Contract
What we call health insurance is a contract. When you get health insurance, you (or somebody on your behalf) are agreeing to a contract with a health insurance company – a contract where they agree to do certain things for you in exchange for money. So a health insurance plan is a contract between the insurance company and the customer (you).
For simplicity, I will use the term health plan to mean the actual contract – the specific health insurance product – you get from a health insurance company. (It sounds less weird than saying "an insurance" and is shorter to type than "a health insurance plan".)
One of the things this clarifies is that one health insurance company can have a bunch of different contracts (health plans) to sell. This is the same as how you may have more than one internet company that could sell you an internet connection to your home, and each of those internet companies might have several different package deals they offer with different prices and terms. In exactly that way, there are multiple different health insurance companies, and they each can sell multiple different health plans with different prices and terms.

Understanding Health Insurance: Introduction [healthcare, US, Patreon]
Dec. 8th, 2025 07:41 amPreface: I had hoped to get this out in a more timely manner, but was hindered by technical difficulties with my arms, which have now been resolved. This is a serial about health insurance in the US from the consumer's point of view, of potential use for people still dealing with open enrollment, which we are coming up on the end of imminently. For everyone else dealing with the US health insurance system, such as it is, perhaps it will be useful to you in the future.
Understanding Health Insurance:
Introduction
Health insurance in the US is hard to understand. It just is. If you find it confusing and bewildering, as well as infuriating, it's not just you.
I think that one of the reasons it's hard to understand has to do with how definitions work.
Part of the reason why health insurance is so confusing is all the insurance industry jargon that is used. Unfortunately, there's no way around that jargon. We all are stuck having to learn what all these strange terms mean. So helpful people try to explain that jargon. They try to help by giving definitions.
But definitions are like leaves: you need a trunk and some branches to hang them on, or they just swirl around in bewildering clouds and eventually settle in indecipherable piles.
There are several big ideas that provide the trunk and branches of understanding health insurance. If you have those ideas, the jargon becomes a lot easier to understand, and then insurance itself becomes a lot easier to understand.
So in this series, I am going to explain some of those big ideas, and then use them to explain how health insurance is organized.
This unorthodox introduction to health insurance is for beginners to health insurance in the US, and anyone who still feels like a beginner after bouncing off the bureaucratic nightmare that is our so-called health care system in the US. It's for anyone who is new to being an health insurance shopper in the US, or feels their understanding is uncertain. Maybe you just got your first job and are being asked to pick a health plan from several offered. Maybe you have always had insurance from an employer and are shopping on your state marketplace for the first time. Maybe you have always gotten insurance through your parents and spouse, and had no say in it, but do now. This introduction assumes you are coming in cold, a complete beginner knowing nothing about health insurance or what any of the health insurance industry jargon even is.
Please note! This series is mostly about commercial insurance products: the kinds that you buy with money. Included in that are the kind of health insurance people buy for themselves on the state ACA marketplaces and also the kind of health insurance people get from their employers as a "bene". It may (I am honestly not sure) also include Medicare Advantage plans.
The things this series explains do not necessarily also describe Medicaid or bare Medicare, or Tricare or any other government run insurance program, though if you are on such an insurance plan this may still be helpful to you. Typically government-run plans have fewer moving parts with fewer choices, so fewer jargon terms even matter to them. Similarly, this may be less useful for subsidized plans on the state ACA marketplaces. It depends on the state. Some states do things differently for differently subsidized plans.
But all these different kinds of government-provided health insurance still use some insurance industry jargon for commercial insurance, if only to tell you what they don't have or do. So this post may be useful to you because understanding how insurance typically works may still prove helpful in understanding what the government is up to. Understanding what the assumptions are of regular commercial insurance will hopefully clarify the terms even government plans use to describe themselves. Just realize that if you have a plan the government in some sense is running, things may be different – including maybe very different – for you.
On to the first important idea: Health Insurance is a Contract.

Substitution Cipher Based on The Voynich Manuscript
Dec. 8th, 2025 12:04 pmHere’s a fun paper: “The Naibbe cipher: a substitution cipher that encrypts Latin and Italian as Voynich Manuscript-like ciphertext“:
Abstract: In this article, I investigate the hypothesis that the Voynich Manuscript (MS 408, Yale University Beinecke Library) is compatible with being a ciphertext by attempting to develop a historically plausible cipher that can replicate the manuscript’s unusual properties. The resulting ciphera verbose homophonic substitution cipher I call the Naibbe ciphercan be done entirely by hand with 15th-century materials, and when it encrypts a wide range of Latin and Italian plaintexts, the resulting ciphertexts remain fully decipherable and also reliably reproduce many key statistical properties of the Voynich Manuscript at once. My results suggest that the so-called “ciphertext hypothesis” for the Voynich Manuscript remains viable, while also placing constraints on plausible substitution cipher structures.

"mom's friend a long time ago."
Dec. 7th, 2025 10:53 pmMom and Dad told me tonight about two friends of my brother's, and one of them's mom who was the school nurse at the time so knows all of us as well as being the mom of his friend, who she's run into lately who told her they always remember Chris at this time of year.
Two of the three apparently said especially that it was twenty years this year, and my mom was surprised that they remembered that specifically. But I have a couple friends about my age who had schoolfriends die when they were in school or soon after, and they certainly remember the person and how long it's been. We are lucky enough to live in an age when child/young person death is rare enough to stand out.
The school nurse mom even told my mom about how her daughter's kids know about him because the daughter has a Christmas ornament with a photo of my brother on it which my parents had made and handed out to people the Christmas after (I got one too, in my terrible flat in West Didsbury, but I never really wanted it and lost it along the way). The kids know about all the ornaments on their tree so they know this one is for "Mom's friend who died a long time ago." I love that.
On a kinda rough day, before two days in London for work that I'm dreading, this was a nice moment.
Their mom and my brother had been friends since kindergarten, when she was one of the girls who called him Kissyfur after a cartoon of that time, and who he used to entertain by doing stuff like pretending not to notice when the girls put snow in his hat and he put it on anyway so they could all laugh.
She sang at his funeral, which is such a gift to be able to offer a peer, when you're only twenty-one.

Reading. Pain, Abdul-Ghaaliq Lalkhen. I want to be very, very clear: unless you are specifically researching attitudes and beliefs in pain clinics in early 2020s England, or similar, do not read this book. There are bad history and no references, appalling opinions on patients (
), quite possibly the worst hyphenation choice I have ever seen, stunning omissions and misrepresentations of pain science, and It's Weird That It Happened Twice soup metaphors. Fuller review (or at least annotated bibliography entry) to follow, maybe.
Some further progress on Florencia Clifford's Feeding Orchids to the Slugs ("Tales from a Zen kitchen"), which I acquired from Oxfam in a moment of weakness primarily for EYB purposes at a point when it was extremely discounted. It is primarily a somewhat disjointed memoir for which I am not the target audience, but hey, Books To Go Back In The Charity Shop Pile but that I wouldn't actually hate reading were exactly the goal, so that's a victory. Mostly. I'm a little over halfway through it, sticking book darts on pages that contain recipes for easier reference when I go back through on the actual indexing pass.
I absolutely needed something that was not going to make me furious and furthermore that was not going to be demanding, and there's a new one in the series, so I have now reread several Scalzi: Old Man's War and The Ghost Brigades completed, The Lost Colony in progress.
I've also had a very quick flick through the mentions of Descartes in Joanna Bourke's The Story of Pain, which is my next Pain Book. She does better than everyone else I've read, but I still think she's misinterpreting Treatise on Man. (Why do I have strongly-held opinions on Descartes now. CAN I NOT.)
Playing. ( Inkulinati, Monument Valley )
Cooking. SOUP.
smitten kitchen's braised chickpeas with zucchini and pesto, two batches thereof, because I had promised A burrata to go with and then (1) the supermarket was out of it and (2) the opened part-pack of feta wound up doing two days quite comfortably, so the second batch was required For Burrata Purposes.
I have also established that the pistachio croissant strata works very well in one of the loaf tins if you scale it down to 50% quantities because there were only 3 discount croissants at the supermarket (... because you had to wait and watch the person who got there JUST ahead of you taking Most Of Them...), which also conveniently used up the dregs of the cream that I had in the fridge.
Eating. Tagine out the freezer (thank you past Alex). Relatively fresh dried apple. A very plain lunch at Teras in Seydikemer, which was apparently the magic my digestive system needed to settle itself down! And I am very much enjoying my dark chocolate raspberry stars. :)

Today's News:
Digital ID: ORG warns of mission creep
Dec. 7th, 2025 02:34 pmOn Monday December 8, MPs will debate the introduction of a national digital ID card. The debate has been instigated by a UK parliament petition that has almost 3 million signatures.
In advance of the debate, Sara Chitseko, Pre-Crime Programme Manager at Open Rights Group said:
“Despite political and public opposition, the government is embarking on a digital surveillance infrastructure that could fundamentally change how we live. Once a national digital ID system is in place, mission creep is inevitable, forcing people to use it more and more in everyday life and opening the door to unprecedented tracking of our interactions with the State.
“Public trust in this scheme has been further undermined by misleading messages over how digital ID will be used.”
New research shows harms of digital ID for migrants.
Migrants in the UK are already subjected to an extensive digital ID regime through the eVisa scheme, which has been be-set with problems from the outset. Migrants have been unable to prove their right to be in the UK as a result of data errors, glitches and Internet outages. These failings have led to people being prevented from travelling, having job offers and mortgages withdrawn, and even being made homeless. New research based on indepth interviews with over 40 migrants, finds that digitalisation has left migrants stressed, confused and fearful. In addition, those with limited digital literacy, language barriers, disabilities or a lack of access to the internet experience have experience more harms and exclusion.
Chitseko added:
“The claim that digital ID is needed to enforce immigration policy is simply false: migrants in the UK are already subjected to an extensive digital ID regime through the eVisa system, and their experiences should serve as a warning. Data errors, glitches and outages have repeatedly left people unable to prove their right to be in the UK—stripping individuals of dignity and basic rights.
“No one should be exposed to a system this fragile. Instead of scaling up these harms and spending £1.8 billion on a population-wide surveillance scheme, the government should be fixing the problems we already have.”

some good things (a post)
Dec. 6th, 2025 11:28 pm- Breakfast in bed, accompanied by completing my first ever playthrough of the main body of Monument Valley. I think I wound up getting two prompts from A, who also spent a significant chunk of the afternoon attempting to get it working on two different large-format touchscreen devices -- I'd been struggling with the trackpad, and was gratified when A reported that they'd had a go at playing the very first level with a trackpad and it really was kind of wretched. (Made it to approximately halfway through Appendix 1 before deciding I needed to call it for the day...)
