Another Data Point

More evidence concerning the sincerity of our current government's commitment to helping the poorest and most vulnerable among us:

Almost all of the state's poorest residents will have to show proof of US citizenship to continue getting medical care by July 1, under a little-noticed federal law that could endanger coverage for many, as Massachusetts is trying to expand access to healthcare.

Born out of ongoing efforts in Washington to clamp down on illegal immigration, the new federal requirement compels anyone seeking Medicaid coverage to provide a birth certificate, a passport, or another form of identification in order to sign up for benefits or renew them.

No such proof is required now.

The requirement was tucked into the Deficit Reduction Act of 2005, which President Bush signed into law earlier this year.

The measure was part of an effort to limit the skyrocketing growth of federal entitlement programs. It has surfaced as Massachusetts begins to implement its sweeping healthcare plan, which aims to bring health coverage to almost all of the state's uninsured, in part by enrolling those in Medicaid who are eligible but who have not signed up.

Healthcare specialists voiced fear that because many Medicaid recipients -- including the homeless and the mentally disabled -- won't be able to easily produce documentation of their citizenship, they will have difficultly receiving care at community health centers, hospitals, or anywhere else.

''So we've got people in nursing homes, people in the [state Department of Mental Retardation] institutions, we've got the homeless, we've got the . . . mentally ill who now will have to come up with some verification to prove that they're citizens," said Victoria Pulos, health law attorney at the Massachusetts Law Reform Institute. ''It's ironic that this is happening in the state where part of the health reform plan is to make sure that everyone who's eligible for Medicaid is enrolled."
