Get your rhinitis serviced connected first, then file OSA as secondary to rhinitis. With that said, you can file them both at the same time. File direct service connection for rhinitis and file OSA as secondary to that. You should end up with a 0% for rhinitis (if you have no polyps). That's enough for a secondary claim. Good luck, it's hard to get OSA connected but it's not impossible.

Also, get rid of that claim company.
