Revision of Hip or Knee Replacement with CC
MDC 08 — Diseases and Disorders of the Musculoskeletal System and Connective Tissue
This DRG was retired after V43.1 and does not exist in V44.0. A claim grouped under a current version will never return 467. Rules and worklists that name it by number stop matching rather than erroring.
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 3.4252 to 3.6259. A dash means the DRG did not exist in that version.
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, and switch the version dropdown to see what replaced this one.
