How a case is assigned to DRG 368

The grouper first assigns the case to MDC 06 from the principal diagnosis and finds no qualifying operating-room procedure (this is a Medical DRG; ICD-10-PCS codes do not drive assignment here), then applies the severity split from secondary diagnoses: with MCC → 368; with CC → 369; without CC/MCC → 370.
