title: Clarifying selected CPT modifiers.
abstract: This discussion includes only 20 percent of the modifiers available for physician reporting, but could account for 80 percent of modifiers assigned for physician services. Modifier -91 was the only new modifier introduced in CPT 2000 and it is used to report a repeat clinical diagnostic laboratory test. It is not to be used when confirming initial results or for any other reason other than a clinical need to repeat the test for the same patient on the same day. Success with CPT modifier reporting requires a thorough review of CPT guidelines and some detective work for identifying health plan requirements for modified codes.
