This is what is stated on the APA site:
CMS issues clarification on billing codes for testing services
Clarifications address issues of when more than one code can be billed and when psychologists can bill for professional time
By Communications and Government Relations staff
December 8, 2011—In response to advocacy efforts by government relations staff at the APA Practice Organization and the Epilepsy Foundation, The Centers for Medicare and Medicaid Services (CMS) issued clarification on Medicare billing and payment policy for the use of Current Procedural Terminology (CPT®) codes when billing for psychological or neuropsychological testing services. The testing codes were revised in 2006 to enable psychologists and physicians to bill for testing services administered by a technician or computer.
As explained further below, the clarification addressed issues of when more than one code can be billed and when psychologists can bill for professional time as well as for testing administered by a technician or computer, among other issues. A complete list of the questions and answers addressed by CMS is available on the CMS website.
Billing for more than one code
The responses provided by CMS clarified that when more than one test is administered on the same date to the same patient, the appropriate testing codes for psychological or neuropsychological testing by a physician/psychologist, technician or computer can be billed together. In addition, the agency explained that more than one code can also be billed when a psychologist needs to consolidate separate written reports and interpretations from distinct tests administered by technician or computer to the same patient on the same date into a comprehensive report.
Previously, some Medicare Administrative Contractors allowed psychologists to bill for testing by a physician/psychologist and testing by a technician or computer during the same encounter, while others did not. This information from CMS will resolve inconsistencies among the various Medicare Administrative Contractors on how to bill for testing services.
This would lead me to believe that there has been a change in policy. Other sites state that you need to use Modifier 59 (some say on each claim line, some say not on the first claim line).
I am confused...
