Looking for forums, and websites for reference on Hospital, Office, Facility, etc Billing Rules, Procedures to properly bill Health Insurance Companies? Also a list of CPT Codes, with descriptions? A nice forum with informative answers and questions on what Rev Codes, Modifiers, CPT or HCPS codes are used, what changes are made, how different States and Insurance Companies follow different guidelines, etc? Thanks for any help at all. Have a great day.
