Pay now or pay later: providing interpreter services in health care.

Research amply documents that language barriers impede access to health care, compromise quality of care, and increase the risk of adverse health outcomes among patients with limited English proficiency. Federal civil rights policy obligates health care providers to supply language services, but wide gaps persist because insurers typically do not pay for interpreters, among other reasons. Health care financing policies should reinforce existing medical research and legal policies: Payers, including Medicaid, Medicare, and private insurers, should develop mechanisms to pay for interpretation services for patients who speak limited English.
