April 1 (Reuters) - Fitch does not anticipate any credit

impact on not-for-profit hospitals in the United States from the

cyberattack at UnitedHealth's ( UNH ) tech unit Change

Healthcare that caused disruption to pharmacies across the U.S.,

the ratings agency said on Monday.

The agency said it does not see any negative rating

implications tied to the hack if the care providers can return

to normal operations in the near term and maintain a

large-enough cash cushion.

The cyberattack at Change, disclosed on Feb. 21 and

initially attributed to "suspected nation-state associated

cybersecurity threat actor", was later blamed on hackers who

identified themselves as the "Blackcat" ransomware group.

Change Healthcare is a vital lynchpin in the system for

making and clearing insurance claims as it processes roughly

half the medical claims in the United States.
