Edit: my first response is all too detailed. The broad effect will be that employers aren't encouraged to provide health insurance, and people trying to buy coverage individually may be completely unable to do so because the combination of "no individual mandate" and "no denial for pre-existing conditions" will lead to insurance companies dying and/or premiums being raised astronomically. Or they'll bring back rejections for pre-existing conditions and then if you ever get sick you'll be actually refused insurance after that.

---my original answer:

Here's one example: If the current bill passes, every health insurance plan that offers coverage for elective abortions will stop being eligible for subsidies on December 31. Every plan in California is required to include this coverage, so effectively all subsidies for individually purchased plans in California will end this year. Another: most federal funding to Planned Parenthood will be banned, leading to the closure of almost all their facilities. About 1 million Californians visited Planned Parenthood last year, perhaps you or your partner were among them (more likely if you are lower income). Or perhaps you weren't, but any medical care you needed was better because your doctor wasn't also trying to meet the needs of all those people who did use Planned Parenthood.
