The Health Care Benefits segment offers a full range of insured and self-insured (“ASC”) medical, pharmacy, dental and behavioral health products and services.
The segment results for the three and six months ended June 30, 2024 and 2023 were as follows:
Total revenues increased 21.4% for the three months ended June 30, 2024 compared to the prior year driven by growth in the Medicare and Commercial product lines.
Adjusted operating income decreased 39.1% for the three months ended June 30, 2024 compared to the prior year primarily driven by increased utilization and the unfavorable impact of the previously disclosed decline in the Company’s Medicare Advantage star ratings for the 2024 payment year within the Medicare product line, higher acuity in Medicaid primarily attributable to the resumption of redeterminations, as well as a change in estimate related to the individual exchange business risk adjustment accrual for the 2023 plan year recorded in the second quarter of 2024. These decreases were partially offset by a favorable year-over-year impact of prior period development and an increase in net investment income.
The MBR increased to 89.6% in the three months ended June 30, 2024 compared to 86.2% in the prior year driven by increased utilization and the unfavorable impact of the Company’s Medicare Advantage star ratings for the 2024 payment year within the Medicare product line, as well as the higher acuity in Medicaid and the change in estimate related to the individual exchange business risk adjustment accrual described above. These increases were partially offset by the favorable year-over-year impact of prior period development.
Medical membership as of June 30, 2024 of 27.0 million increased 200,000 members compared with March 31, 2024, reflecting increases in the Medicare and Medicaid product lines, including the commencement of the Medicaid Oklahoma contract on April 1, 2024.
Prior years’ health care costs payable estimates developed favorably by $623 million during the six months ended June 30, 2024. This development is reported on a basis consistent with the prior years’ development reported in the health care costs payable table in the Company’s annual audited financial statements and does not directly correspond to an increase in 2024 operating results.
Days claims payable were 43.1 days as of June 30, 2024, a decrease of 1.4 days compared to March 31, 2024. The decrease was primarily driven by elevated reserves held in the first quarter of 2024, including the impact of the Change Healthcare cyberattack.
