DRG_TABLE

This table provides helpful context and categories around Diagnosis Related Groups (DRGs) for inpatient medical billing.

What is a Diagnosis Related Group (DRG)?

A patient classification scheme that groups patients into categories based on their principal diagnosis, secondary diagnoses, surgical procedures, age, sex, and discharge status. DRGs are used to determine hospital reimbursement rates under Medicare's Prospective Payment System (PPS).

Bespoke nature of DRG creation can be messy

The creation of DRGs is a deeply human process. Individual judgement and relationship dynamics play an outsized role in the creation and determination of DRG codes and the corresponding financial values - and many of these nuances are not recorded in a reliable fashion.

  • 🏥 DRGs are assigned to patients based on information reported by the hospital on the Medicare Inpatient Hospital Discharge Data (MS-DRG) abstract.
  • 🕓 These abstracts contain information about the patient's primary diagnosis, up to 24 additional diagnoses, and up to 25 procedures performed during the stay.
  • ☔ DRGs are used by Medicare and other payors to make payments to hospitals for inpatient stays.
  • 💸 Transparency of both clinical logic going into DRG code determinations (and the price coming out) are frequently obfuscated by

All in all, CareQuery® leverages the comprehensive longitudinal record of patients to articulately arrive at a reliable DRG determination for inpatient visits, helping users to comprehensively look through the DRG lens, despite the DRG's traditional data lineage shortcomings.
