DRG Mapping Rules for 0NH344Z

To determine how a PCS code will affect MS-DRG grouping, you must first look at the patient's primary diagnostic code. The patient will be grouped into the first MDC that lists the primary diagnostic code in the "Assignment of Diagnosis Codes" section.

From there, check the subsections of the MDC. The patient will be mapped into the first subsection for which the treatment performed on the patient meets the listed requirements of that subsection. It most cases, the rules are based based on the PCS codes of the services performed. Sometimes multiple PCS codes are required to qualify.

DRG grouping rules are adjusted each year, so make sure to check the rules for the fiscal year of the patient's discharge date.

About the Turquoise Health MS-DRG Manual Browser

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.
