Gov. J.B. Pritzker signed a bill expanding insurance coverage for Illinoisans suffering from Lyme disease and discussed other health-related measures at a news conference in his State Capitol office Tuesday.

The Democrat also touted a bill which requires insurers to cover the cost of medically necessary epinephrine shots for children, and once again said he was open to signing a “stronger” bill pertaining to the emissions of ethylene oxide, a known cancer-causing chemical, in Illinois.

House Bill 889, signed Tuesday, requires insurance companies to cover long-term antibiotic therapy, office visits, testing and treatment for tick-borne diseases such as Lyme disease. It takes effect immediately and opens the door for coverage of experimental drugs if they are federally approved.

Well, it takes a team. It takes the 101st General Assembly, the House and the Senate to push this forward.

Jennifer Russell, director of the Illinois Lyme Association, said her daughter, Laura, is nearing the end of several years of treatment for Lyme disease.

“This legislation is pivotal in the state of Illinois,” she said. “Many in Illinois are suffering from tick-borne illness. Those with state-regulated insurance or private pay are in most cases only receiving 21 days of treatment. … Many are losing their homes, their businesses and their pensions to try to pay for the continued treatments, and this legislation provides them with desperately needed options.”

Rep. Jonathan Carroll, a Northbrook Democrat, was the sponsor of the bill to expand epinephrine coverage to all persons 18 years of age and younger beginning Jan. 1, 2020.

“We are now on the forefront of food allergy safety in Illinois,” he said.

Pritzker noted the cost of an epinephrine injection, known commonly by its brand name EpiPen, has risen 400 percent in recent years, now costing close to $700 without insurance, and the medication
