Principal diagnoses that group to MS-DRGs 834–836

From the CMS MS-DRG definitions manual’s principal-diagnosis index: 33 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 834–836 the case lands in. The 24 most-searched:

  • C92.00Acute myeloblastic leukemia, not having achieved remission
  • C91.00Acute lymphoblastic leukemia not having achieved remission
  • C91.01Acute lymphoblastic leukemia, in remission
