INDIANAPOLIS | Enrollment in Indiana's cigarette-tax funded health insurance program for the working poor has surpassed 20,000, state officials announced Wednesday.

The Healthy Indiana Plan has drawn 64,494 applications since its December launch. As of this week, 21,186 low-income adults are receiving coverage.

"With Governor Daniels' leadership and bi-partisan support from Representative Charlie Brown, D-Gary, and Senator Pat Miller, R-Indianapolis, we have been able to reach this exciting milestone," Indiana Family and Social Services Secretary Mitch Roob said in a statement.

The health care plan, funded by a 44-cent cigarette tax hike, has the resources to cover 130,000 Hoosiers, though Roob previously set a 50,000 target for the first year.

The plan is targeted to adults, age 19 to 64, who have gone without access to health insurance for at least six months and earn up to double the federal poverty line, or $20,800 for a single person. Enrollees must pay into the plan up to 5 percent of their annual income based on a sliding scale that begins at 2 percent for individuals earning $10,400 or less.

This month, the state began offering a buy-in option for uninsured adults with higher incomes. For them, the cost will range from about $125 month for a 25-year-old male to $550 a month for a 60-year-old female.

Healthy Indiana Plan participants each gain access to at least $500 in annual preventive care, such as mammograms and prostate exams, and receive a $1,100 annual health savings account to cover doctor visits and other medical expenses. Those who exhaust those accounts can tap up to $300,000 in additional annual insurance coverage.
