Which MS-DRGs does Q39.5 group to?

Q39.5 sits in MDC 06 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.

  • 368Major Esophageal Disorders with MCCmedical
  • 369Major Esophageal Disorders with CCmedical
  • 370Major Esophageal Disorders without CC/MCCmedical

As a secondary diagnosis, Q39.5 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
