Fact: Nothing in HIPAA requires electronic claims submission. However, you may be required to submit Medicare claims electronically under a separate law enacted in 2001—the Administrative Simplification Compliance Act (ASCA). Under the ASCA, all Medicare claims must be submitted electronically by October 16, 2003; however, small providers (including physicians with fewer than 10 full-time equivalent employees) are excluded. Of course, once providers start submitting claims electronically to Medicare, they become covered providers under HIPAA and are subject to all of the administrative simplification regulations.
