denied claim

what is the number one reason for a denied claim? Which is the most preventable denied claim?

re: denied claim

For this type of question I always check with Medicare first, for two reasons - one, they have the built-in claim checks and error rate testing so along with the most claims they also have the best data; and two, because private insurers tend to fall into Medicare guidelines on most issues eventually.

This is a great guide on the top claims errors for the NGS jurisdictions (sorry for the long link):

You can Google "top claim denials" but most of the articles just refer back to the same issues as Medicare, with less obvious data sources.
