I had individual health insurance. Can my group coverage health insurance deny pre-ex conditions?

As long as you have had creditable coverage with no break longer than 63 days you will not have a pre-existing condition exclusion. Here is the government website with more information on the regulations: a href="http://www.dol.gov/ebsa/faqs/faq_consumer_hipaa.html" rel="nofollow"http://www.dol.gov/ebsa/faqs/faq_consume…/a
