Two ways to group

One patient at a time, or all at once.

Check individual patients with Code Assist, or group whole datasets in bulk with the Batch Grouper.

Code Assist

Check each patient, one by one.

Enter a single patient's codes, group them instantly and verify the result. Ideal for coders reviewing cases, coding audits and training.
