SANTA FE, N.M. — New Mexico Attorney General Hector Balderas is demanding answers from a northern New Mexico hospital that ended obstetrical and delivery services six months ago.

Balderas sent letters last week to leaders of the Alta Vista Regional Hospital in Las Vegas and said the closure had left an unacceptable gap in services for women in the area.

The sudden closure left dozens of pregnant women without a local hospital to deliver newborns.

The Democrat stopped short of threatening any action but said he is “tasked with oversight of charitable organizations in New Mexico.”

Hospital spokeswoman Linda Leyba says the hospital is preparing a response that includes additional information on our progress in re-opening an obstetrics program.

The hospital previously said the closure was due to “market conditions.”
