On August 22, 2008, HHS published a proposed rule that would adopt updated versions of the standards for electronic transactions under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The rule also would adopt a transaction standard for Medicaid Pharmacy Subrogation and two standards for billing retail pharmacy supplies and professional services, and would clarify who the “senders” and “receivers” are in the descriptions of certain transactions. HHS will accept comments on the proposed rule until October 21, 2008.
