Driscoll Children's Hospital announced Thursday that it now hosts a Level 4 NICU, or Neonatal Intensive Care Unit.

Driscoll's NICU was officially designated following a rigorous site visit conducted by the American Academy of Pediatrics' NICU Verification Program earlier this year.

Level 4 is the highest level of care available for premature and critically-ill newborns.

Driscoll Children's Hospital serves an area of South Texas that covers 31 counties.
