UnitedHealth unit Change faces issue processing some medical claims

(Reuters) -UnitedHealth Group said on Thursday it had resolved an issue that had hampered processing of batches of medical claims for some customers of its technology unit, Change Healthcare.

A fix has been implemented and is being monitored to ensure operability, Change operator Optum, said in a statement, before confirming the issue was resolved.

A spokesperson for Optum told Reuters the incident may have affected "a small subset and customers may have already been communicated", and that the company will provide more information when it has any.

It was not clear if the latest incident was related to a widespread hack in February or the resolution process following the attack.

The company was still working on resuming operations that were disrupted by the February hack, and on Tuesday said it expects a hit of up to $1.6 billion this year from the cyber attack.
