MD/VA/DC FEHB - Federal Employee insurance question

Wondering if anyone happens to know anything about this…

For those of you who are federal employees in the DMV area and have health insurance through the FEHB- do you have insurance that allows you to see docs across state lines? I figure there has to be something set up for those of us who live/work in this area and have a practitioner across the state line.

I’m working for a contractor but will be starting on the federal side soon.

Thanks in advance!
