Administrative Simplification works to streamline administrative health care transactions and set standards for transmitting electronic health information. The National Standards Group (NSG) within the Office of Healthcare Experience & Interoperability (OHEI) enforces Administrative Simplification standards, which aim to reduce burden and lower costs by standardizing business practices.
