There is no other law that can modify or change the COBRA rights. That said, you could obtain a certificate of continuous coverage and obtain regular insurance without having any restrictions for pre-existing conditions. However, that is not really part of COBRA, but is part of HIPAA. You can see much more detail about your portability rights under HIPAA by going to: http://www.dol.gov/ebsa/faqs/faq_consumer_hipaa.html
