Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC
Assigned before MDC logic runs, so it is driven by the procedure rather than the principal diagnosis. The grouper still reports the principal diagnosis's own MDC on a grouped claim.
CMS publishes classification in the Definitions Manual and weights in Table 5 of the IPPS rule, one spreadsheet per year. These are the 9 versions this grouper supports.

Range 5.1563 to 5.6154. A dash means the DRG did not exist in that version.
10 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.
