Appendix 1 Census Data Self Insured HMO RFP~2.xlsx

This file is a Census Data appendix supporting an RFP issued by the Illinois Department of Central Management Services (CMS) for the administration of self-insured HMO plans covering four employee benefit programs: the State Employees Group Insurance Program (SEGIP), Local Government Health Plan (LGHP), Teachers Retirement Insurance Program (TRIP), and College Insurance Program (CIP). The appendix provides detailed enrollment data and demographic information segmented by program, geographic region, age groups, salary bands, and other relevant classification categories to enable potential vendors to accurately model costs and assess the scope of the self-insured HMO administration services required. This census data serves as the foundational actuarial and planning information that prospective proposers must utilize to develop their responses and financial proposals for administering these multiple health plans across the Illinois public sector.

The census data presented in the appendix is essential for vendors to understand the covered populations, their distribution across the four programs, and the anticipated claims experience and administrative requirements associated with each program. This information enables proposers to develop realistic pricing models, operational plans, and service delivery approaches tailored to the specific enrollment profiles and geographic spread of participants. The data allows bidders to assess the complexity and scale of the HMO administration mandate and to formulate competitive proposals that reflect the actual administrative and claims management costs associated with serving these distinct but overlapping employee populations throughout Illinois.
