Wiki Coding audit

[dgoj]

I am a manager of the billing office for an independent laboratory. Our coders assign ICD-9 codes to diagnoses that are provided to us as verbiage.

I need to audit my coders and I'm wondering if someone can suggest a way to determine how many claims or individual codes to look at for accuracy in order to make the audit valid. Currently we audit a certain number of claims per every 100 claims coded.

Any suggestions on other ways to determine how many claims to look at or how your audit is conducted?

Thanks.
