The Indiana State Uniform Billing Committee (I-SUBC) is a consortium of healthcare providers, payers (government and commercial), software vendors, and consultants dedicated to cost-effective institutional billing through the uniform billing format (UB-04). The committee meets quarterly to review, comment and act - both proactively and reactively - on initiatives impacting healthcare institutional billing at the national and state level. I-SUBC is an ad hoc committee of the Indiana Pressler Memorial Chapter of HFMA and is supported by HFMA, AAHAM and through the volunteerism of its membership.
