Optum provides health insurance coverage for families and individuals within the state of California, and like most health insurance providers, there will be some coverage for the treatment of a substance use disorder. Optum health plans include plans for employers, and individuals and families, and when struggling with a drug problem, it will be good knowing you have health insurance to cover some of the costs. Anytime you are searching for a drug treatment center in California, you should contact your insurance provider and find out what will be covered by your plan. Optum does help provide health insurance for many Americans who reside in California, and unfortunately; a percentage of these Americans do struggle with a drug or alcohol addiction. The treatment of a drug problem should be done right away, and the longer that you wait, the worse the addiction will become. Regardless of how severe addiction may be; most insurance plans will provide some basic coverage for state-funded and private programs, and it is a good idea to consider both options.
