Range 10.7707 to 11.4404. A dash means the DRG did not exist in that version.
528 ICD-10-PCS procedures. Each maps here on its own; procedure clusters can also reach this DRG through combinations, listed separately below. Too many to list: this is a catch-all class that sweeps in most of the code set, so the count is more informative than the codes.
Relative weight is not payment: actual reimbursement also applies wage index, capital, DSH and IME adjustments, and outliers. Group an encounter to see which DRG it actually lands in.
