If you want DRGs assigned to some records and you don't want to buy, install and run the software yourself, then our DRG Assignment Service (DAS) might be just what you are looking for.
The DAS works like this: you send us your dataset with some information about the file format and the record format. With that information, our software can find the data elements used in assigning DRGs. We run your dataset through our grouper and return the results to you along with a DRG summary report which gives you an overview of your dataset's DRG profile: a frequency distribution of DRGs assigned and errors encountered.
An additional advantage of the DAS is that we can automatically infer the appropriate DRG version to use if your dataset contains a discharge date. So if your data spans versions, you don't have to buy additional masks files.
In order to keep things simple all the way around, we offer this service as a flat fee by number of records in the input. If you can provide your data in any of the formats listed below, then you qualify for the flat fee schedule below. If not, it is likely that we can still help you, but you would have to contact us for a custom price quote.

  • Microsoft Office 2000 through 2010 (Access or Excel);

  • ASCII or EBCDIC text file with one record per line (either variable-width fields with a separator or fixed-width fields are ok);

  • SQL INSERT statements in a text file (either ASCII or EBCDIC);

  • MySQL database dump.

As part of the standard DAS, we offer two processing options: either we will use any supported DRG version on all your records or we will use the discharge date (which must be included in your dataset) to determine which federal DRG version was in use at the time of discharge and then use that version. Other methodologies for determining what version to use are possible, but would fall under the category of custom set-up programming and would require a custom quote.

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.

As part of the standard DAS, we will return any combination of the following data elements as fields in the output dataset:
  • Grouper Return Code (what error, if any, arose during grouping);

  • DRG Version used to group the record;

  • DRG Number assigned the record;

  • Major Diagnostic Category (MDC) of the assigned DRG;

  • The resource consumption weight of the assigned DRG;

  • The official description of the assigned DRG.

[Top of Page]
We can return these values in one of the following ways:
  1. At the beginning of the output dataset;

  2. At the end of the output dataset;

  3. As contiguous fields starting at a given field number;

  4. As separate records with the same ID as the grouped input record (assuming that the input record has an ID field and that you have told us which field to use as the ID).
