215 ILCS 125/4-6.1
A policy subject to this subsection shall not impose a deductible, coinsurance, copayment, or any other cost-sharing requirement on the coverage provided; except that this sentence does not apply to coverage of diagnostic mammograms to the extent such coverage would disqualify a high-deductible health plan from eligibility for a health savings account pursuant to Section 223 of the Internal Revenue Code (26 U.S.C. 223).
For purposes of this Section:
"Diagnostic mammogram" means a mammogram obtained using diagnostic mammography.
"Diagnostic mammography" means a method of screening that is designed to evaluate an abnormality in a breast, including an abnormality seen or suspected on a screening mammogram or a subjective or objective abnormality otherwise detected in the breast.
"Low-dose mammography" means the x-ray examination of the breast using equipment dedicated specifically for mammography, including the x-ray tube, filter, compression device, and image receptor, with radiation exposure delivery of less than 1 rad per breast for 2 views of an average size breast. The term also includes digital mammography and includes breast tomosynthesis.
"Breast tomosynthesis" means a radiologic procedure that involves the acquisition of projection images over the stationary breast to produce cross-sectional digital three-dimensional images of the breast.
If, at any time, the Secretary of the United States Department of Health and Human Services, or its successor agency, promulgates rules or regulations to be published in the Federal Register or publishes a comment in the Federal Register or issues an opinion, guidance, or other action that would require the State, pursuant to any provision of the Patient Protection and Affordable Care Act (Public Law 111-148), including, but not limited to, 42 U.S.C. 18031(d)(3)(B) or any successor provision, to defray the cost of any coverage for breast tomosynthesis outlined in this subsection, then the requirement that an insurer cover breast tomosynthesis is inoperative other than any such coverage authorized under Section 1902 of the Social Security Act, 42 U.S.C. 1396a, and the State shall not assume any obligation for the cost of coverage for breast tomosynthesis set forth in this subsection.
Care shall be determined in consultation with the attending physician and the patient. The offered coverage for prosthetic devices and reconstructive surgery shall be subject to the deductible and coinsurance conditions applied to the mastectomy and all other terms and conditions applicable to other benefits. When a mastectomy is performed and there is no evidence of malignancy, then the offered coverage may be limited to the provision of prosthetic devices and reconstructive surgery to within 2 years after the date of the mastectomy. As used in this Section, "mastectomy" means the removal of all or part of the breast for medically necessary reasons, as determined by a licensed physician.
Written notice of the availability of coverage under this Section shall be delivered to the enrollee upon enrollment and annually thereafter. A health maintenance organization may not deny to an enrollee eligibility, or continued eligibility, to enroll or to renew coverage under the terms of the plan solely for the purpose of avoiding the requirements of this Section. A health maintenance organization may not penalize or reduce or limit the reimbursement of an attending provider or provide incentives (monetary or otherwise) to an attending provider to induce the provider to provide care to an insured in a manner inconsistent with this Section.
