NRC Health, a publicly-traded company that says it works with 75 percent of the 200 largest U.S. hospital chains, was hit with a cyberattack on Feb. 11, a spokesperson confirmed to CNBC. The attack sparked concerns about the security of patient health information stored on NRC Health's servers.

The company could not confirm whether any patient information or confidential information was accessed by the hackers. It didn't share details on the nature of the attack but said it doesn't have evidence of a patient data breach.
