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, 2023 and 2022 were as follows:
Total revenues increased 17.6% for the three months ended June 30, 2023 compared to the prior year driven by growth across all product lines.
Adjusted operating income decreased 19.9% for the three months ended June 30, 2023 compared to the prior year, reflecting increased outpatient utilization in Medicare Advantage when compared with pandemic influenced utilization levels in the prior year, as well as the impact of lower year-over-year prior period development. These decreases were partially offset by higher net investment income in the three months ended June 30, 2023 compared to the prior year and the continuing benefit of operating expense leverage.
The MBR increased to 86.2% in the three months ended June 30, 2023 compared to 82.7% in the prior year driven by increased outpatient utilization in Medicare Advantage when compared with pandemic influenced utilization levels in the prior year, as well as the impact of lower year-over-year prior period development.
Medical membership as of June 30, 2023 of 25.6 million increased 121 thousand members compared with March 31, 2023, reflecting increases in the Commercial and Medicare product lines. These increases were partially offset by a decline in the Medicaid product line, primarily attributable to the resumption of Medicaid redeterminations following the expiration of the public health emergency.
The segment experienced unfavorable development of prior-periods’ health care cost estimates in its Government Services business during the three months ended June 30, 2023, primarily attributable to first quarter 2023 Medicare Advantage performance. This was partially offset by favorable development of prior-periods’ health care cost estimates in the segment’s Commercial business during the three months ended June 30, 2023.
Prior years’ health care costs payable estimates developed favorably by $612 million during the six months ended June 30, 2023. 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 2023 operating results.
