If you want to loop through a data set and assign a DRG to each record, then you need one of our batch groupers: DRGFilt or MHDRG DLL.
Every year the US Federal government releases a new DRG version. The earliest version we sell through our on-line store is Version 10, which we call "f10" for Federal Version 10.
The official release is on October 1st every year and we usually release our implementation of the algorithm by October 15th every year.
Please specify which version you need for any of our products. Our software is backwardly compatible, so if you buy the version 20 grouper, that module can handle versions 10 through 20, assuming that you have purchased the appropriate masks file.
NOTE: We have support for versions 2 through 9, but demand is low enough that we do not clutter up our on-line store with them. You can purchase support for versions 2 through 9, but only by contacting us directly.

DRGFilt is a console application and a UNIX-style "filter." This means that it reads from its standard input and writes to its standard output. DRGFilt respects a "control file" which tells it how to pick out its input fields from each record and were to put its output fields into each record. Typically, you assign DRGs to an entire data set with the following steps:
  1. Export your data from your database into an ASCII text file
  2. Create a DRGFilt control file to match your data
  3. Run DRGFilt on your ASCII text file, which produces a new ASCII text file
  4. Input the new ASCII text file into your database
There is more detailed information about using DRGFilt on our technical support page.

Excel-DRG is a Microsoft Excel spreadsheet which calls our Grouper DLL to assign DRGs to its rows.
Included in the Excel-DRG purchase price is
  • Excel macro to call DLL
  • sample Excel spreadsheet with macro
  • Current Grouper DLL
  • DRG Masks file of your choice
If you want to interactively group records and then store the results, look at Access-DRG.

As of October, 2009, we have a shiny new on-line shopping cart. We strongly recommend that you use it, if you can. You can use the shopping cart by clicking on the big blue buttons above.
If you use the on-line shopping cart, you get your software immediately and directly.
If you do not use the shopping cart, your order will have to be filled manually, which takes time, and will be emailed to you, which often leads to interference by spam filters and firewalls.
You can use the on-line shopping cart if you have a company credit card; we use Paypal to process on-line purchases, but Paypay does not require you to have or use a Paypal account.
If your company works on a purchase order basis, you may want to fax us a purchase order to (203) 826-2214, containing the same product information as the form below. If you would like to order on-line, but are sure that you cannot use our on-line shopping cart, please fill in the form below and submit it.
(If you are reading the PDF version of this document, then please consider copying the form and pasting it into a email or printing it out and faxing it or mailing it.)

If you don't get an email acknowledgement from us within 2 business days, there may have been some technical problem so please let us know at grouper@drggroupers.net.
