More than 400,000 people thought to be eligible for Medicaid and CHIP appear to have their eligibility determinations caught in the healthcare.gov web site.

Through a flaw in the federal health care web site, eligibility notifications for these applicants have not been forwarded to state governments and the applicants have not been enrolled in Medicaid or CHIP.

Some states have received only some Medicaid and CHIP verifications from the federal web site while a few have not received any.

Aware of the problems with the federal site, some newly eligible individuals and families reapplied on the federal site or went directly to their state governments but others have not and still have not been notified of their eligibility for the two programs months after they applied and had their eligibility initially approved.

Because they serve so many low-income and uninsured patients, private safety-net hospitals have a special interest in the resolution of this problem.
