Issue with Access-DRG and Weights

BUG REPORT

Access-DRG is showing the decimal point in the wrong place for DRG weights, eg Access-DRG reports the weight for DRG 2 as 1.1754 instead of 11.7540.


INVESTIGATION

We confirmed the issue on our Windows validation platform. We confirmed that
this bug did NOT exist on our reference platform. We checked our records and found that our initial drgmasks.f27 file had the decimal place in the wrong place for some weights which was detected as part of quality control. However, we failed to update the canonical image with the corrected file, resulting in at least some customers getting the bad masks file.


RESOLUTION

We confirmed that running the newly updated installer for the f27 masks file corrects the problem. We are sending the bug reporting customer an update right away and working to update our site as soon as possible.

Do not run the masks file "uninstall" as we have an open ticket in which a user claims that running the masks file uninstall removes all masks files, not just the one you want to remove.

If you are not sure if your installation is correct, please run the following test case through our system and see what is returned as the DRG weight; alternately, you can simply download either the Windows installer or masks file directly below.
