Which MS-DRGs does D82.1 group to?

D82.1 sits in MDC 16 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.

  • 808Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with MCCmedical
  • 809Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with CCmedical
  • 810Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders without CC/MCCmedical

As a secondary diagnosis, D82.1 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from D80-D89

The conditions below can never be reported together with D82.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • autoimmune disease (systemic) NOS (M35.9)
  • functional disorders of polymorphonuclear neutrophils (D71-)

Excludes1 — never code together — inherited from D82

The conditions below can never be reported together with D82.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • ataxia telangiectasia [Louis-Bar] (G11.3)

Excludes2 — not included here — inherited from Chapter 3

The conditions below are not part of D82.1, but a patient may have both at the same time. When documentation supports it, D82.1 and the excluded code may both be reported.

  • 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)

Excludes2 — not included here — inherited from D80-D89

The conditions below are not part of D82.1, but a patient may have both at the same time. When documentation supports it, D82.1 and the excluded code may both be reported.

Which codes are confused with D82.1?

ICD-10-CM declares these codes mutually exclusive with D82.1 — exactly one of each pair can be correct for a given encounter.
