Federal health officials announced a new round of financial help Tuesday to ease the financial strains on safety-net health-care providers in the coronavirus pandemic, committing $25 billion to hospitals and other providers of care for the nation’s poorest patients.

The Department of Health and Human Services plans to devote $10 billion of that amount to about 750 hospitals that treat many patients on Medicaid or who are uninsured, officials said. The other $15 billion will go to doctors, dentists, clinics and other facilities that treat low-income adults and children, if they have not received assistance through two earlier rounds of federal aid to providers coping with the pandemic’s effects.
