HHS released an interim final rule with comment period offering guidance on the operation of electronic health care transactions under HIPAA. The rule implements portions of Sec. 1104 of the Affordable Care Act (ACA), and it is expected to save $9 billion over the next 10 years "by reducing inefficient manual administrative processes for physician practices, hospitals, and health plans," HHS said. Comments on the rule, which is scheduled to be published in the Aug. 10 Federal Register, are due Oct. 9.
