Should coders already be double-coding (coding accounts in both ICD-9 and ICD-10)?

Yes. All coders should be double-coding accounts at this time. This will familiarize the coder with the ICD-10 code set as well as the updated Grouper screen. It is also an excellent way to evaluate the provider’s documentation. This is important because it will allow facilities to know whether or not they need to complete additional ICD-10 documentation training for their providers.
