Using ICD-10 codes for diagnoses

The list of billable ICD-10 codes available from the CMS gets updated annually on October 1st. We update these codes regularly, meaning that codes you previously used may become outdated. It’s important to use current codes for diagnoses, whether you file insurance claims or not.

How can I tell if a code is billable?

Every year on October 1st, the list of billable ICD-10 codes is updated. This means that diagnosis codes you previously used may become outdated. To confirm a code’s current description and to check if it’s billable:

  • Confirm the code has the current year and is listed as a Billable/Specific Code


How do I update a code in a client’s file?

The list of billable ICD-10 codes is updated every year on October 1st. Whether you file insurance claims or not, you’ll need to make sure that you update your client records.

Important: If you need to submit claims for any appointments that took place prior to October 1st, make sure not to include any post-October 1st appointments. If a claim has been rejected due to an invalid ICD code, you’ll need to update the client’s file, delete, and recreate the claim. Before deleting a rejected claim, download a copy and note the clearinghouse reference number.

If a diagnosis code(s) you use has been modified, you can update the client’s file. To do this:

  • Navigate to the client's profile
  • Click New > Diagnosis and treatment plan
  • Select the new Diagnosis Code
    • Update the Description if needed
  • Set the Date and time of diagnosis to a date on or after last October 1st

  • Click Save
