To get a definitive answer to your question as well as other questions regarding the status of nurse aide certifications and work history contact the Louisiana CNA - DSW Registry at 225-342-0138. That being said, as far as I know, to determine if a CNA is excluded by either the federal Office of Inspector General or State Medicaid Program Integrity, check the Louisiana Department of Health and Hospitals Adverse Actions website at this link. To understand what the codes given as reasons for exclusion mean please see this page.
