As noted above, software vendors provide computer software applications support to health care clearinghouses and health care providers. They particularly work with health care providers’ practice management and health information systems. We believe these entities would be affected positively, at least in the short term. The implementation of administrative simplification would enhance their business opportunities as they would be involved in developing computerized software solutions that would allow for health care providers and other entities that exchange health care data to integrate the new transaction set into their existing systems. They may also be involved in developing software solutions to manage the crosswalk of existing health care provider and health plan identifiers to the national provider identifier and health plan identifier (PAYERID) until such time as all entities have implemented the identifiers.
