Correct. Rejected are not charged as they are a clerical error and are going to be resubmitted.
Denials get charged (BTW, CO is 3rd highest in the USA for denials at 3.6% and has a 58.8% overturn rate... If I was wrong 60% of the time, I would consider my system fucking broke!)
ACCIDENTAL RESUBMITTALS get charged as a new submittal. Instacheck will glitch sometimes if you refresh the page immediately after submitting a check and double submit the check. To stop this from happening, click on the link to the left to recall the submittal screen.
