 ===== DRG =====
-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.
-==== Sources ====
-The vocabulary is retrieved from [[http://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/Acute-Inpatient-Files-for-Download.html/|the Centers for Disease Control and Prevention (CDC) Website]]
-==== Domains ====
-All DRG concepts are of the Observation domain.
-==== Сoncept Classes ====
-  * DRG
-  * MS-DRG
-==== ETL process ====
-  - 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.
