Which MS-DRGs does T84.51XA group to?

T84.51XA sits in MDC 08 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 403Hip or Knee Procedures with Principal Diagnosis of Periprosthetic Joint Infection with MCC or Insertion of Antibiotic-eluting Bone Void Fillersurgical
  • 404Hip or Knee Procedures with Principal Diagnosis of Periprosthetic Joint Infection without MCCsurgical

As a secondary diagnosis, T84.51XA is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
