The National Uniform Billing Committee (NUBC) is a voluntary committee whose work is coordinated through the offices of the American Hospital Association and includes participation of all the major national provider and payer organizations. The committee was originally formed to develop a single standard billing format and data set to be used nationwide by institutional providers and payers for handling health care claims. Today, the Committee monitors and manages the utilization of this standard uniform (UB) billing form and data set used throughout the industry wide for billing transactions.
