In even more words, absolutely - pansexual people aren't cishets, are they? They're simply not highlighted in the most commonly used 'LGBTQ' acronym, but it is more specifically featured in some of the longer ones (LGBTQAP or LGBTQQIAAP). However, pan still falls under the queer/questioning label (queer, that is- obv pan doesn't mean you're confused :3) So yes, you're definitely still LGBTQ.
