Which MS-DRGs does L03.321 group to?

L03.321 sits in MDC 09 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 573Skin Graft for Skin Ulcer or Cellulitis with MCCsurgical
  • 574Skin Graft for Skin Ulcer or Cellulitis with CCsurgical
  • 575Skin Graft for Skin Ulcer or Cellulitis without CC/MCCsurgical

As a secondary diagnosis, L03.321 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
