The report contains medical claims, prescription drug claims, enrollment, and expense information as furnished by Blue Cross Blue Shield of Arizona (Whyzen Analytics reporting tool) through December 31, 2025. For the month of December, Medical paid claims were approximately $3,400,700 while net Rx claims were about $619,700. For the 2025 plan year to date, claims and expenses (after stop- loss reimbursements and pharmacy rebates) exceeded contributions by approximately $8,784,400 or 29.6% of contributions. Based on paid claims and expenses, Actives and Retirees on the Red Plan, Blue Plan, and White Plan experienced an operating deficit, as displayed on Page 8. There are fifty-five claimants with paid claims in excess of $100,000 during the reporting period. There are six claimants in the current plan year to date who have exceeded the stop loss deductible of $350,000. Expenses included in this report are medical plan administration, stop-loss premium, capitation for behavioral health & chiropractic services, value-based services, out-of-network shared savings costs, HSA administration, and fees associated with the Affordable Care Act. Also included is the amount of $126,692 per month from the estimated 2025 Operating Budget. These expenses exclude those funded by Blue Cross Blue Shield of Arizona. These expenses include categories such as wellness incentives, personnel support, audit & financial services, promotional, operating supplies & equipment, bank charges, contractual services, and health savings and flex account contributions. In December 2025, approximately 36.8% of all active employees and retirees were enrolled in the Red plan, with 5.3% enrolled in the Blue plan, and 57.9% enrolled in the White plan. The average total enrollment in 2025 is approximately 1.1% higher than the 2024 average enrollment.

(2) The amount that plan participants enrolled in the White plan pay for their prescription drugs is not included in the Pharmacy Spend and Pharmacy Per Script Metric sections of the Dashboard because the information is not available broken down by pharmacy category in the BCBSAZ Whyzen system. Differences in pharmacy spend may also be due to the reporting data source. (3) Cost share means the member's out-of-pocket expense compared to the sum of plan paid claims plus member out-of-pocket. Percentages do not reflect employee contributions. (4) Percentages are rounded to the first decimal. (5) Dashboard Large Claims data is taken from the BCBSAZ Whyzen reporting tool, which is a utilization "snapshot in time" possibly resulting in a difference between the dashboard and the monthly report. 5976824 Financial Prescription Drugs (Rx) Enrollment Medical Utilization Medical Network Medical/Rx Plan Design Month Enrollment Contributions1 Medical Paid2,3 Stop Loss Refunds Rx Paid Rx Rebates Net Claims Expenses4 Total Paid Claims and Expenses Surplus/ (Deficit) Total Loss Ratio Jan-24 1,837 $2,255,077 $2,391,086 ($121,423) $410,269 $0 $2,679,932 $327,895 $3,007,827 ($752,750) 133.4% Feb-24 1,871 $2,282,167 $1,181,504 ($92,637) $432,642 $0 $1,521,510 $386,675 $1,908,185 $373,982 83.6% Mar-24 1,866 $2,276,847 $1,419,172 ($20,165) $414,950 $0 $1,813,957 $395,792 $2,209,748 $67,098 97.1% Apr-24 1,861 $2,267,739 $1,725,393 ($8,572) $409,060 $0 $2,125,881 $428,808 $2,554,689 ($286,950) 112.7% May-24 1,867 $2,269,373 $1,793,138 $0 $543,123 $0 $2,336,261 $393,110 $2,729,371 ($459,998) 120.3% Jun-24 1,866 $2,268,861 $1,764,187 ($1,853) $591,275 $0 $2,353,608 $390,143 $2,743,751 ($474,890) 120.9% Jul-24 1,879 $2,282,875 $1,783,173 ($67,503) $560,440 $0 $2,276,109 $428,029 $2,704,139 ($421,264) 118.5% Aug-24 1,879 $2,285,642 $1,861,896 ($2,003) $565,136 $0 $2,425,029 $401,274 $2,826,303 ($540,662) 123.7% Sep-24 1,873 $2,282,149 $1,649,463 ($477) $515,968 $0 $2,164,953 $411,554 $2,576,508 ($294,358) 112.9% Oct-24 1,881 $2,290,288 $1,446,977 ($18) $526,203 $0 $1,973,162 $394,475 $2,367,637 ($77,349) 103.4% Nov-24 1,880 $2,290,795 $1,219,703 $0 $586,109 ($319,040) $1,486,772 $409,738 $1,896,510 $394,285 82.8% Dec-24 1,886 $2,297,060 $1,620,147 ($40,176) $546,539 $0 $2,126,510 $406,916 $2,533,427 ($236,367) 110.3% 2024 Total 22,446 $27,348,873 $19,855,837 ($354,825) $6,101,713 ($319,040) $25,283,685 $4,774,410 $30,058,094 ($2,709,222) 109.9% 2024 Avg. 1,871 $2,279,073 $1,654,653 ($29,569) $508,476 ($26,587) $2,106,974 $397,867 $2,504,841 ($225,768) 109.9% Jan-25 1,888 $2,466,316 $1,305,024 ($24,025) $445,129 $0 $1,726,127 $421,069 $2,147,196 $319,120 87.1% Feb-25 1,888 $2,463,414 $1,597,614 ($883) $458,094 ($176,701) $1,878,125 $425,517 $2,303,642 $159,772 93.5% Mar-25 1,886 $2,466,464 $2,482,351 ($897) $379,806 $0 $2,861,261 $431,031 $3,292,292 ($825,827) 133.5% Apr-25 1,883 $2,461,954 $2,248,996 ($44,893) $575,693 $0 $2,779,796 $429,998 $3,209,794 ($747,839) 130.4% May-25 1,871 $2,448,132 $2,424,209 ($240) $486,142 ($172,934) $2,737,178 $431,398 $3,168,576 ($720,443) 129.4% Jun-25 1,875 $2,452,954 $2,005,554 ($411) $600,164 $0 $2,605,307 $402,132 $3,007,439 ($554,484) 122.6% Jul-25 1,882 $2,463,067 $2,865,701 ($26) $580,271 $0 $3,445,946 $414,929 $3,860,875 ($1,397,808) 156.8% Aug-25 1,893 $2,479,584 $2,468,819 ($98,917) $525,941 ($186,362) $2,709,481 $445,941 $3,155,422 ($675,838) 127.3% Sep-25 1,892 $2,475,194 $2,658,890 ($1,648) $650,647 $0 $3,307,889 $411,447 $3,719,337 ($1,244,143) 150.3% Oct-25 1,901 $2,489,674 $2,983,630 ($212,167) $720,400 ($199,888) $3,291,975 $429,803 $3,721,778 ($1,232,105) 149.5% Nov-25 1,914 $2,501,278 $2,218,334 ($328,599) $665,265 $0 $2,555,000 $448,245 $3,003,245 ($501,967) 120.1% Dec-25 1,917 $2,509,478 $3,400,703 ($623,073) $619,656 $0 $3,397,286 $475,078 $3,872,364 ($1,362,887) 154.3% 2025 Total 22,690 $29,677,509 $28,659,826 ($1,335,778) $6,707,209 ($735,885) $33,295,371 $5,166,587 $38,461,958 ($8,784,449) 129.6% 2025 Avg. 1,891 $2,473,126 $2,388,319 ($111,315) $558,934 ($61,324) $2,774,614 $430,549 $3,205,163 ($732,037) 129.6% 2 City of Chandler 2024-2025 Medical/Rx Contributions and Expenses Year-to-date through December 2025 (1) Contributions for COBRA are assumed to be the same as the Actives.
