MS-DRG 809: MAJOR HEMATOLOGICAL AND IMMUNOLOGICAL DIAGNOSES EXCEPT SICKLE CELL CRISIS AND COAGULATION DISORDERS WITH CC

DRGMedicalMDC 16

MS-DRG 809 is major hematological and immunological diagnoses except sickle cell crisis and coagulation disorders with cc, in MDC 16 (a medical DRG), at the with-CC (complication or comorbidity) level. Its FY2027 relative weight is 1.2262, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 3.30 days. 63 ICD-10-CM principal diagnoses group into MS-DRGs 808–810 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 808–810

From the CMS MS-DRG definitions manual’s principal-diagnosis index: 63 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 808–810 the case lands in. The 24 most-searched:
