Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code D55.21 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 811 | RED BLOOD CELL DISORDERS WITH MCC | 16 | 1.3776 |
| 812 | RED BLOOD CELL DISORDERS WITHOUT MCC | 16 | 0.8797 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
