Standardization (ISO). ANSI does not produce standards itself but functions as an accreditor of SDOs through its Accredited Standards Committee (ASC). ANSI primarily ensures that SDOs adhere to the principles of openness, balance of interests, due process, and an appeals process and approves standards that could become U.S. national standards. ANSI does not perform quality checks on the data interchange standards developed or distribute standards interpretation and implementation guides for consistency. Several primary SDOs in the United States develop the various types of data interchange standards required for health care data (see Box 3-1).
Other independent groups are involved indirectly. They include the National Uniform Billing Committee, which develops a single billing form and standard dataset to be used nationwide by institutional providers and payers for handling health care claims, and the National Uniform Claims Committee, which develops a standardized dataset for use by the noninstitutional health care community in transmitting claim and encounter information to and from all third-party payers.
