How a case is assigned to DRG 621

The grouper first assigns the case to MDC 10 from the principal diagnosis, then matches a qualifying operating-room procedure from the ICD-10-PCS list below (this is a Surgical DRG), then applies the severity split from secondary diagnoses: with MCC → 619; with CC → 620; without CC/MCC → 621.
