CTPF-Sponsored Health Insurance Program
Choosing a health insurance plan for you and your eligible dependents is one of your most important decisions. CTPF sponsors comprehensive health insurance plans designed to promote wellness and provide high-quality coverage at a reasonable cost. CTPF offers health insurance benefits to retirees, dependents, and survivors if the retiree's final teaching service was with the Chicago Public, Charter or Contract Schools.
Qualified retirees may enroll in a plan for:
- Non-Medicare eligible members
- Medicare-eligible members who maintain enrollment in Medicare Part A and Part B
- Eligibility & Enrollment Requirements
CTPF retirees/survivors and their eligible dependents may qualify to enroll in a CTPF health insurance plan. To qualify, CTPF must be the retiree’s final retirement system. A retiree/survivor and/or dependent may initially enroll in a CTPF plan once in a lifetime unless they experience a qualifying event. A member who leaves a CTPF plan after initial enrollment may re-enroll in a CTPF health insurance plan one time (during Open Enrollment) without a qualified change in status, with proof of prior medical and prescription drug coverage.
Visit the Health Insurance page for a list of eligibility and enrollment requirements for CTPF plans.
