Most open enrollment for the Affordable Care Act ends Sunday.
A record 16 million people have signed up since November. More than three million of them are new sign-ups.
The government says the Affordable Care Act is gaining popularity after federal enhancements reduced the price.
Most people can find plans that cost less than $10 a month.
Even after open enrollment ends, Americans who lose health care or have very low income can still sign up throughout the year.
