The AIS Data Team has posted new data to the subscriber dashboard Online Search Tool and In-App Download Enrollment Data Spreadsheets. This data primarily reflects third-quarter 2025 status but includes fourth-quarter 2025 data for Medicare Advantage (MA), dual-eligibles and some Medicaid membership.

Most related in-app downloads and special reports now reflect the most recent data available. Keep an eye out in the coming weeks for a detailed analysis of changes from the second quarter of 2025.

For this update, we added two MCOs, PACE plans based in California and New York, respectively: K-Day PACE (#2088) and PACE at Hudson HeadWaters (#2089)

We discontinued three MCOs:

• myPlace PACE (#2055), which was acquired by SCAN Health Plan (#154) in 2025;
• Sonder Health Plans, Inc. (#2013), which left the Medicare market in summer 2025 due to financial difficulties; and
• Stockton PACE (#1973), which was consolidated under WelbeHealth (#2079).

We updated one MCO name: Taro Health (#2043) is now Mending (fka Taro Health), after the insurer rebranded.

Notable Enrollment Changes

Decreases in the Medicaid space were once again larger than last quarter: Medicaid HMO membership fell by 660K, while Medicaid FFS decreased by 165K lives since the second-quarter update.

Notable insurer-level changes in the managed Medicaid space since the last update include the following:

• Decreases in California and Texas fueled the bulk of the top 10 Medicaid plans that lost membership this quarter, with L.A. Care Health Plan (#564) losing the most members in one state (dropping 43K members in California).
• Centene also lost the most members nationally, more than 109K, due to reductions in several states.
• Only Kaiser Foundation Health Plan, Inc. (#134) and Triple-S Management Corporation (#1196) gained more than 10K Medicaid members, adding roughly 13K each.

Public exchange figures leveled out after decreasing nearly 429K in the second quarter; the market lost less than 12K members this quarter.

The following insurers saw the highest shifts in the public exchange space:
• Aetna (#1359), which is exiting the public exchange market for 2026, once again lost the most ACA members, losing nearly 37K.
• Florida Blue (#11) lost roughly 27K exchange members in the third quarter, after losing 10% of its exchange membership in the second quarter.
• UnitedHealthcare (#1263) rebounded in the public exchange space, gaining nearly 45K in the third quarter.

Commercial group risk enrollment again decreased since the second quarter, dropping nearly 478K members, fueled by losses in the large group market (391K). ASO/self-funded plan membership decreased at a modest rate, losing 27K members since last quarter.

Notable changes in commercial group include:

• UnitedHealthcare lost 74K group risk members, alongside a 40K loss in ASO/self-funded membership.
• Health Alliance (#315) lost nearly 72K group members (82% of its group membership) in the third quarter, as part of its withdrawal from all markets by the end of 2025.
• While Aetna lost 36K group risk members since the second quarter, this decrease was more than offset by its gain of 63K ASO members.

Medicare Advantage (MA) and duals plans gained more than 148K members; because the plan year begins in January, this segment doesn’t see major quarterly shifts. However, UnitedHealthcare attracted more than 53K new members from the last update, the largest increase overall.
