-Diagnosis-related group (DRG) is a patient classification system that standardizes prospective payment to hospitals and encourages cost containment initiatives. In general, a DRG payment covers all charges associated with an inpatient stay from the time of admission to discharge. +Thank you for visiting ​the wiki! This page has moved to https://github.com/OHDSI/Vocabulary-v5.0/wiki/Vocab.-DRG.

-==== MS-DRG ====  +
-A Medicare Severity-Diagnosis Related Group is a classification system (referred to as DRG) for inpatient discharges, which adjusts payments under the Inpatient Prospective Payment System (IPPS) based on appropriate weighting factors assigned ​to each DRG. In OMOP CDM, MS-DRG is represented as the separate concept_class_id of DRG. +

-  - 1. If event_date <= 2007-09-30 source DRG codes should be mapped to source_vocabulary_id = '​DRG'​ and source concept_class_id = '​DRG'​ +
-  - 2. If event_date >= 2007-10-01 source DRG codes should be mapped to source vocabulary_id = '​DRG'​ and source concept_class_id = '​MS-DRG'​ +
- +
-Note: MS-DRG codes of '​156',​ '​155',​ '​251','​154',​ '​250'​ should be filtered using "​invalid_reason is null" due to the intersecation of valid dates.+
