LRB104 17044 RLC 30459 b
A BILL FOR
		HB4583		LRB104 17044 RLC 30459 b
    AN ACT concerning criminal law.
    Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
    Section 5. The Unified Code of Corrections is amended by
adding Section 3-6-9 as follows:
    (730 ILCS 5/3-6-9 new)
    Sec. 3-6-9. Treatment for committed persons with substance 
use disorders.
    (a) The General Assembly finds the followings:
        (1) The Department of Corrections does not currently 
    have extensive medication-assisted treatment programs 
    readily available to meet the needs of all committed 
    persons with opioid use disorder, despite estimates that 
    more than half of the committed population meets the 
    criteria for having a substance use disorder.
        (2) Providing timely access to medication-assisted 
    treatment in correctional settings reduces recidivism, 
    overdose risk following release, and improves treatment 
    retention. Withholding evidence-based opioid use disorder 
    treatment increases risk for death during detention and 
    upon release.
        (3) According to the Department of Human Services, up 
    to 75% of parolees who leave prison without treatment for 
		HB4583	- 2 -	LRB104 17044 RLC 30459 b
    an identified substance use disorder resume substance use 
    within 3 months of release.
        (4) Studies demonstrate that in the first 2 weeks 
    after release, the risk of opioid overdose is 40 times 
    higher for those who were incarcerated compared to the 
    general population.
        (5) It is the stated position of the U.S. Substance 
    Abuse and Mental Health Services Administration that no 
    justification exists for denying access to medications for 
    opioid use disorder because psychosocial services are 
    unavailable or individuals are unwilling to avail 
    themselves of those services.
        (6) The U.S. Department of Justice has determined that 
    individuals with opioid use disorder are protected under 
    the Americans with Disabilities Act of 1990.
        (7) In community-based settings, such as opioid 
    treatment programs and primary care facilities, 
    medication-assisted treatment has been proven to reduce 
    overdose deaths and illicit opioid use. Individuals with 
    opioid use disorder living in correctional settings are 
    entitled to the same level of care as those in 
    community-based settings.
    (b) In alignment with the State of Illinois Overdose 
Action Plan, the purpose of this Section is to facilitate 
timely access to medication-assisted treatment options and 
therapies to all individuals under the care of the Department 
		HB4583	- 3 -	LRB104 17044 RLC 30459 b
of Corrections who are diagnosed with opioid use disorder.
    (c) In this Section:
    "Authorized health care professional" means a physician 
licensed to practice medicine in all its branches, a licensed 
physician assistant with prescriptive authority, a licensed 
advanced practice registered nurse with prescriptive 
authority, an advanced practice registered nurse or physician 
assistant who practices in a hospital, hospital affiliate, or 
ambulatory surgical treatment center and possesses appropriate 
clinical privileges in accordance with the Nurse Practice Act, 
or a pharmacist licensed to practice pharmacy under the 
Pharmacy Practice Act.
    "Department" means the Department of Corrections.
    "Medication-assisted treatment" means the use of U.S. Food 
and Drug Administration-approved medications, in combination 
with counseling and behavioral therapies, to provide a whole 
patient approach to the treatment of substance use disorders.
    (d) The Department shall ensure all persons under its care 
are assessed for substance use disorder, as defined in the 
Substance Use Disorder Act. This process includes screening 
and assessment for opioid use disorders. For a committed 
person diagnosed with opioid use disorder, the Department 
shall offer, or facilitate access to, all medication-assisted 
treatment options deemed appropriate by an authorized health 
care professional. The Department shall not impose limitations 
on the types of medication assisted treatment that may be 
		HB4583	- 4 -	LRB104 17044 RLC 30459 b
recommended by an authorized health care professional as part 
of a treatment plan.
    (e) An individual receiving medication-assisted treatment 
prior to being committed to a Department of Corrections 
facility shall be entitled to, upon request, continue such 
treatment in the medication assisted treatment program for any 
period of time deemed medically necessary by an authorized 
health care professional. No person shall be denied 
participation in medication-assisted treatment program on the 
basis of a positive drug screening upon entering the 
Department's custody; nor shall any person receive a 
disciplinary infraction for such positive drug screen. No 
person shall be denied participation in medication-assisted 
treatment based on prior success or failure of any 
medication-assisted treatment program.
    (f) For each Parole District, the Department shall develop 
a plan to facilitate access to medication-assisted treatment 
for persons diagnosed with opioid use disorder in the 
community following release.
    (g) The Department may adopt rules for the implementation 
of this Section.
    Section 99. Effective date. This Act takes effect January
1, 2027.
