TRANSPARENCY IN DOWNCODING ACT

What this bill does

Creates the Transparency in Downcoding Act. Provides that the Act applies to certain policies of health insurance amended, delivered, issued, or renewed on or after the effective date of the Act, except for employee or employer self-insured health benefit plans under the federal Employee Retirement Income Security Act of 1974 and health care provided pursuant to the Workers' Compensation Act or the Workers' Occupational Diseases Act. Prohibits a health insurance issuer from using an automated process, system, or tool to downcode a claim; from downcoding a claim based solely on the reported diagnosis codes; and from using downcoding practices in a targeted or discriminatory manner against physicians who routinely treat patients with complex or chronic conditions. Requires downcoding decisions to be made by a physician licensed to practice medicine in all its branches in any United States jurisdiction and of the same or similar specialty as a physician who typically manages the medical condition or disease. Sets forth provisions concerning notification requirements for downcoded claims; the appeal process for downcoded claims; enforcement by the Department of Insurance; and penalties. Provides that any pattern or practice of discriminatory downcoding identified by the Director of Insurance or another regulatory authority shall be subject to enforcement actions, including fines, restitution, or suspension of the health insurance issuer's license in this State. Effective immediately.

How does a bill become law in Illinois?
  1. Introduction of Bill

    A member of the Senate or the House introduces a bill, which is assigned a unique identifying number (e.g., "H.B. ___" for House bills and "S.B. ___" for Senate bills). If not enacted, it must be reintroduced in the next General Assembly with a new number.

  2. Committee Work — Hearings

    The bill goes to the appropriate committee, which holds hearings to gather expert opinions and determine the need for the legislation.

  3. Committee Work — Markup, Amendments, Report

    The committee may make amendments to the bill. If approved, a committee report endorsing the bill is issued.

  4. Floor Debate

    The bill is debated and can be further amended. The debate transcripts are accessible online for public viewing.

  5. Passage and Consideration in Second Chamber

    If the bill passes in the first chamber, it moves to the second chamber for a similar review process. If both chambers approve, it goes to the governor.

  6. Gubernatorial Action

    The governor can sign the bill into law, veto it, or take no action (resulting in an automatic law after 60 days). The type of veto can be total or amendatory. Once signed, the bill becomes a Public Act and is assigned a Public Act number.
