Which MS-DRGs does D59.4 group to?

D59.4 sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Inclusion terms

Alternative wording in documentation that is classified to D59.4.

  • Mechanical hemolytic anemia
  • Microangiopathic hemolytic anemia
  • Toxic hemolytic anemia

Excludes2 — not included here — inherited from Chapter 3

The conditions below are not part of D59.4, but a patient may have both at the same time. When documentation supports it, D59.4 and the excluded code may both be reported.

  • autoimmune disease (systemic) NOS (M35.9)
  • certain conditions originating in the perinatal period (P00-P96)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • human immunodeficiency virus [HIV] disease (B20)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

How long has D59.4 existed?

D59.4 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
