We build tools and machine learning systems that simplify healthcare revenue cycle operations. We were frustrated with the formatting of the MS-DRG rules, so we built our own solution.
MS-DRG rules and ICD-10 CM/PCS codes are automatically parsed from CMS's MS-DRG data files. All content is provided strictly “AS IS” and may contain parsing errors. If you spot an error, please let us know.
We have converted the MS-DRG logic into fully structured, machine-readable data. If you need structured data versions of the MS-DRG manuals, we would love to talk with you.
