SANTA FE, N.M. (AP) — Gov. Susana Martinez's administration says a proposed revision of Medicaid will require only some eligible Native Americans to obtain health services through managed care organizations.

The Human Services Department said Tuesday the federal government has accepted parts of a planned overhaul of the program providing health care for a fourth of New Mexico's population.

Indians qualifying for Medicare and Medicaid or needing nursing home care will obtain health services through managed care organizations. Other Indians will continue having an option of managed care or a fee-for-service system.
