Feb 21 (Reuters) - UnitedHealth Group-owned Change Healthcare said on its status page that it was hit by a cybsecurity attack on its systems on Wednesday, saying the disruption will last at least through the day.

The Tennessee-based company, which is a national provider of healthcare cost transparency and consumer engagement solutions, said it was facing enterprise-wide connectivity issues that started at 05:05 ET (10:05 GMT).

"Once we became aware of the outside threat, in the interest of protecting our partners and patients, we took immediate action to disconnect our systems to prevent further impact," Change Healthcare said on its status page, adding that its experts are working to address this matter.

It didn't give more details regarding the cybersecurity issue.

Change Healthcare did not immediately respond to a Reuters request for comment.
