The latest numbers also show 2,153,421 people have enrolled in the ACA nationally.
Leafman says there's a reason 41 percent of those enrolled have chosen the gold and platinum plans.
"A good percentage of people buying those plans are people who have medical conditions who are currently being treated that have a good idea of what their course of treatment is going to be," Leafman said.
Meaning, despite the higher initial costs they'll save in the end because there's more comprehensive coverage.
But the silver plan is still the most popular nationally and in Arizona 48 percent of those enrolled opted for that plan.
"The greatest numbers of plans appear under the silver level which is supposed to cover 70 percent of a person's average medical bills," Leafman said.
Updated numbers are expected after the next open enrollment deadline March 31st, 2014.
