I have an insurance where you have to submit your reimbursement forms via mail. For some reason this has been quite challenging to me (printer, stamp, envelope etc.) and I didn’t submit things.

A provider pointed me to reimbursify which made it way simpler as you pay per claim and it just mails the reimbursement to the insurance. I think this reimbursify may be also helpful in cases like this if you want to speed run your reimbursement submission :).

Note: I am not affiliated with reimbursify but just a happy customer even though the UX&app are somehow clunky. Still better than the other options.
