Currently in the United States, health insurance is not required federally as of January 1, 2019 but some states have laws that require health insurance coverage to avoid a tax penalty. There are risks associated with not having health insurance, such as getting injured and facing medical financial hardships, or facing financial hardship due to something unpredictable like the flu. There are several tiers of health coverage: Bronze, Silver, Gold, and Platinum. Respectively these mean that the policy works out to them paying 60 and you paying 40 (Bronze); they pay 70 and you pay 30 (Silver); they pay 80 and you pay 20 (Gold), and they pay 90 and you pay 10 (Platinum). California specifically offers what is called a “minimum coverage plan” for those under thirty, which has lower premiums and protect from worst-case scenarios and cover three doctor and urgent care visits; after that, it is full price.
The way that most basic health inurances work is that you both share the costs that your wellness care may accrue up until a certain point, and then the health insurance policy covers the rest up to 100% of the expenses. Up until that point, the policholder is responsible for copayment of things such as medicines or wellness practices not fully covered by insurance. For example, wisdom teeth removal may be necessary but only for some of the teeth based on their position: due to this, part of the procedure is considered “cosmetic” and does not garner full coverage. Basic health care usually covers most doctor visits, prescriptions, and other care in regards to wellness. Health insurance does not cover elective or cosmetic procedures or procedures that are extremely new and subject to error. In specific situations, policyholders can appeal and give more information regarding their individual context in order for a re-evaluation to be done.
