21 ICD-10-PCS procedures. Each maps here on its own; procedure clusters can also reach this DRG through combinations, listed separately below.
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.
