Question: My wife read that the deadline was December 7th. I thought it was December 15th. Who’s right.
Answer: You’re right this time. December 15th is the deadline for individuals and families in the under-65 health insurance market. You must enroll or make changes to your plan by December 15th to affect coverage on January 1st whether you enroll through Covered California or directly with an insurance company. Open enrollment in California extends until January 31st for new enrollments or changes to existing plans with effective dates to February 1st 2020.
Your spouse is correct if she is on Medicare. The deadline for changes to 2018 Medicare coverage is December 7th.
