Other Myeloproliferative Disorders or Poorly Differentiated Neoplastic Diagnoses: Inpatient Reimbursement Overview
DRG 845 addresses inpatient stays for other myeloproliferative disorders or poorly differentiated neoplastic diagnoses without Complication or Comorbidity or Major Complication or Comorbidity. It defines the clinical scope and relative resource use used to determine Medicare inpatient reimbursement for lower-acuity hematology and oncology admissions.
DRG 845 Overview
DRG 845 covers hospital inpatient admissions for patients with other myeloproliferative disorders or poorly differentiated neoplastic diagnoses without a Complication or Comorbidity or a Major Complication or Comorbidity. Clinically this includes primary hematologic proliferative disorders and cases where definitive neoplastic classification is not established during the stay. This Diagnosis-Related Group matters for Medicare payment because it assigns a base payment relative to the expected resources for these less complex hematology oncology admissions. Accurate coding and documentation of diagnosis specificity and comorbid conditions affect grouping and reimbursement.
