CLIA program; categorization of tests and personnel modifications--HCFA. Final rule with comment period.

In this rule we are responding to some of the comments on categorization of tests and personnel requirements received in response to rules published on February 28, 1992 and January 19, 1993. (In a future rule, we will be responding to the remaining comments.) We are revising our regulations to: Allow dentists and midlevel practitioners to perform tests in the "physician-performed" microscopy (PPM) subcategory of moderate complexity procedures (we now call the subcategory "provider-performed"); include three additional tests in PPM; and expand provisions relating to general supervisor and high complexity testing personnel.
