- UnitedHealth Group reported lower total revenue but higher profits in the third quarter of 2026, following membership losses in Medicaid and employer-sponsored insurance plans.
- Healthcare providers and insurers are increasingly using artificial intelligence to manage billing, coding and payment disputes, creating what experts describe as a “war of the bots.”
- Optum generated $735 mn in quarterly earnings, nearly 18 times its year-earlier result, and contributed more than half of UnitedHealth’s earnings.
UnitedHealth Group reported a decline in total revenue for the third quarter of 2026, even as profits increased, reflecting changes in its insurance membership and stronger earnings from its healthcare services subsidiary, Optum.
According to the company’s October 13 earnings report, the revenue decline followed the loss of members enrolled in Medicaid and employer-sponsored health insurance plans. Yet lower membership did not translate into weaker profitability.
Howard Forman, a professor of health and economics at Yale University, explained that an insurer’s financial performance depends on the composition of its insured population rather than simply the number of people covered.
Some insurance segments had become less profitable because of the healthcare costs associated with their members. Adverse selection can also affect insurers when healthier individuals leave coverage and those requiring more expensive treatment remain.
Medicare Advantage plans have also faced pressure from members with substantial healthcare needs. UnitedHealth has responded by withdrawing from businesses that generate losses, prioritizing profitability over maintaining its previous market presence.
Changes in healthcare billing practices provide another explanation for the financial pressures facing insurers and providers.
JB Silvers, professor emeritus of health finance at Case Western Reserve University, described an increasing reliance on artificial intelligence by both sides of the healthcare payment process.
According to Silvers, healthcare providers are splitting bills and modifying patient coding to increase reimbursements from insurers. Insurance companies are deploying technology to scrutinize those claims and counter such practices.
UnitedHealth’s diversified business structure has also supported its earnings performance. Its Optum subsidiary operates healthcare clinics, manages pharmacy benefits and provides other healthcare services beyond traditional insurance coverage.
Optum contributed more than half of the group’s earnings during the third quarter, according to Matthew Fiedler, a senior fellow at the Brookings Institution.
The subsidiary generated $735 mn in quarterly earnings, nearly 18 times the amount reported during the corresponding period a year earlier.
Fiedler explained that combining health insurance operations with healthcare delivery services can provide financial advantages. Ownership of healthcare providers may reduce an insurer’s exposure to external providers’ pricing power and improve its negotiating position.
Optum’s earnings growth illustrates the financial contribution of UnitedHealth’s healthcare services operations at a time when its insurance business is adjusting membership and coverage exposure. The subsidiary’s performance helped the group increase profits despite the decline in consolidated revenue.
