Medicare, Medicaid and CLIA programs; revision of the laboratory regulations for the Medicare, Medicaid, and Clinical Laboratories Improvement Act of 1967 programs--HCFA. Final rule with comment period.

This rule revises regulations for laboratories regulated under the Medicare, Medicaid and Clinical Laboratories Improvement Act of 1967 (CLIA '67) programs. The revisions recodify the regulations for these programs into a new part 493 in order to simplify administration and unify the health and safety requirements for all programs as much as possible. We will now have a single set of regulations for the three programs, with an additional subpart for the licensure procedures unique to the CLIA program. We are revising the regulations to remove outdated, obsolete and redundant requirements, make provision for new technologies and place increased reliance on outcome measures of performance. We provide for new uniform proficiency testing standards. We have also added requirements for additional specialties, such as clinical cytogenetics. We also implement the now and self-implementing provisions of the Clinical Laboratory Improvement Amendments of 1988 (CLIA '88).
