215 ILCS 5/356z.8
A group or individual policy of accident and health insurance or managed care plan amended, delivered, issued, or renewed after the effective date of this amendatory Act of the 94th General Assembly must provide coverage for medically necessary preventative physical therapy for insureds diagnosed with multiple sclerosis. For the purposes of this Section, "preventative physical therapy" means physical therapy that is prescribed by a physician licensed to practice medicine in all of its branches for the purpose of treating parts of the body affected by multiple sclerosis, but only where the physical therapy includes reasonably defined goals, including, but not limited to, sustaining the level of function the person has achieved, with periodic evaluation of the efficacy of the physical therapy against those goals. The coverage required under this Section shall be subject to the same deductible, coinsurance, waiting period, cost sharing limitation, treatment limitation, calendar year maximum, or other limitations as provided for other physical or rehabilitative therapy benefits covered by the policy.
