Sets of codes are available that will aid those designing NDW exports. If properly used, they will allow us to provide you better information from your data, including increased accuracy and a wider breadth of reports. To obtain these code sets, click on the following link:

Standard Code Book Tables

Below are some commonly asked questions concerning the Standard Code Book:

What individual or department is responsible for keeping the reference tables up to date?
How do we ask for new codes to be added?
How do we update our facility/community data?
Site &ldquogoing tribal&rdquo or otherwise changing their ASUFAC code. What do we need to consider?

First communicate your plan to your Area Statistical Officer and Area Computer Support representative with as many details as possible for their feedback. Your Area Statistical Officer should share the plan with NPIRS, the Senior Statistician of the Division of Program Statistics (DPS), and the RPMS Database Administrator. Consider/communicate, at a minimum, the following points:

  • Does the new ASUFAC code already exist in the facility SCB? If not, it will need to be added. Send your request as described in the “How do we ask for new codes to be added?” section.
  • When is the change to take effect? If the change is made during the course of one fiscal year, be aware the Workload reports for that year will show counts under both ASUFACs. If the change is to be effective at the end of a fiscal year, and separating workload between the old and new ASUFACs is important, consult with NPIRS on the timing of submissions.
  • Should changes be made to the Active/Inactive status of the old/new facility records?. This status does not affect any NPIRS reporting.
  • Should changes be made to the APC flag of the old/new facility records? This flag determines whether direct outpatient visits to a facility should be counted on workload reports.  
  • Will the site continue to use their existing database after the code change (provide the existing Database ID) or will a new database be created (request a new Database ID)?
  • If the site has Contract Health encounters, will they change who will process their claims? Changes may be needed to the RPMS CHS-MIS package (or other package used by the site) and to the visit claim entry values/procedures. There may be timing issues when changing the authorizing facility since most contract visits are paid well in arrears.
  • Should all the registrants be given new chart numbers under the new ASUFAC? This is not necessary for sites using RPMS because the AUM patch install changes the ASUFAC in the chart record.
Your Area may have had other sites go through this process before and you can benefit from documentation they developed. If not, consider documenting the steps you take and give them to your Area Statistical Officer for future reference. Contact the OIT Help Desk at support@ihs.gov for any other questions.   [Close]
