DRG Coding Advisor
It’s time to update your internal coding guides
The emphasis by Medicare and commercial payers on proper documentation of items such as medical necessity means practices must keep their in-house code books, billing procedures, and staff current on the latest codes to avoid problems getting paid — or even potential audits.
New codes could take longer to implement
Here’s a list of the new ICD-9-CM diagnosis codes used by most physician practices that have been approved for use in FY 2001. These codes became effective Oct.1, 2000. But, it could be several months before they are implemented by most payers. If you have not already, your office should be keying these codes into its information system plus briefing both billers and providers about the changes.
