The HH&H MAC workload for provid-ers in Maine, Massachusetts, New Hampshire, Rhode Island, Vermont, and Connecticut has transitioned from NHIC to National Government Ser-vices, NGS notes in an e-mail message.
Do this: For affected providers, "it will be necessary to remove the legacy contractor number and replace it with the appropriate National Govern-ment Services contractor number, in any data elements in the 837 or 276 files," NGS instructs. "Files transmitted after 5:00 p.m. on Friday, October 18, 2013 must have the new contractor number. Failure to submit the correct contractor number after transition will result in the batch file being rejected," the MAC stresses.
