Uninsured Rate Climbs, Reviving Pre-ACA Coverage Fears

The share of working-age U.S. adults without health insurance is climbing, and it is doing so before the bigger coverage losses that analysts expect in 2026. That has some healthcare leaders invoking the pre-Affordable Care Act era, when more Americans went without coverage and leaned on emergency departments for care they could not get elsewhere, according to Becker's Hospital Review.

The warning draws on the Commonwealth Fund's Biennial Health Insurance Survey, a long-running gauge of coverage trends. The concern is directional as much as numerical: the rate is backsliding now, and additional policy changes threaten to accelerate the decline next year.

For hospitals and health systems, rising uninsurance translates into more uncompensated care, higher reliance on emergency settings, and pressure on already thin margins. For patients, losing coverage often means delaying care until conditions worsen. The practical takeaway for operators is to prepare for a payer mix shift and a possible return to dynamics the ACA was designed to reduce.
