WHY MS-DRGs?
According to the 8/22/07 Final Rule, CMS chose MS-DRGs over the other DRG systems because:
- MS-DRGs remains an improvement over the current CMS DRGs;
- MS-DRGs are more up-to-date (in relation to the review of MCCs & CCs);
- MS-DRGs are understandable;
- MS-DRGs will have fewer transition issues than other systems; and
- MS-DRGs allow for updates and maintenance to continue using the same process as under the current CMS DRGs.
