How a case is assigned to DRG 434

The grouper first assigns the case to MDC 07 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 → 432; with CC → 433; without CC/MCC → 434.
