Overall good implementation of the Illinois HBI program. One notable issue: the senior resource limit parameter ($17,500) exists but is not implemented in the eligibility formula. See summary comment for details and recommendations.

PR Review: Illinois Health Benefits for Immigrants (HBI)

🔴 Critical (Must Fix)

1. HBIA Program Start Date Incorrect
   • File: policyengine_us/parameters/gov/states/il/hfs/hbi/eligibility/adult/in_effect.yaml
   • Current: 2022-01-01: true
   • Should be: 2022-07-01: true
   • Source: Illinois DHS Policy page states "Expanded to ages 42-64 effective July 1, 2022"

🟡 Should Address

1. Missing Test for Pre-July 2022 Period

   • Add test verifying someone aged 42-64 is NOT eligible in January 2022 (before HBIA started for that age group)

2. Add Primary Regulatory Reference

   • Consider adding citation to enabling legislation: 305 ILCS 5/12-4.35 (Health Benefits for Immigrant Adults and Seniors Act)

🟢 Suggestions

1. Senior Income Test Precision

   • In il_hbi_senior_income_level.yaml, test expects 0.777 but calculation is 11700/15060 = 0.7769... - verify rounding behavior

2. Document Enrollment Pause (optional)

   • HBIA enrollment paused July 1, 2023; HBIS enrollment paused Nov 6, 2023
   • Current implementation only models program termination, which is acceptable for most policy analysis

Validation Summary

Check	Result
Regulatory Accuracy	1 issue (HBIA start date)
Reference Quality	✅ References corroborate values
Code Patterns	✅ No hard-coded values, correct patterns
Test Coverage	Good coverage, minor gap
CI Status	✅ Passing (codecov warning is non-blocking)

Verified Correct

• ✅ Age thresholds (All Kids ≤18, HBIA 42-64, HBIS ≥65)
• ✅ Income limits (All Kids 318% FPL, HBIA 138% FPL, HBIS 100% FPL)
• ✅ HBIS start date (Dec 1, 2020)
• ✅ HBIA end date (July 1, 2025)
• ✅ Resource limit ($17,500 for seniors)
• ✅ AABD methodology for seniors vs MAGI for children/adults
• ✅ Immigration statuses (undocumented, DACA, TPS)
• ✅ Vectorized operations (where/select patterns)
• ✅ Parameter access patterns

Next Steps

To auto-fix issues: /fix-pr 7005

Or address manually:

1. Change HBIA start date from 2022-01-01 to 2022-07-01
2. Add test for pre-July 2022 ineligibility
