Summary & Overview
Hypertension without MCC: Inpatient Reimbursement Overview
DRG 305 addresses inpatient stays with a principal diagnosis of hypertension without Major Complication or Comorbidity, focusing on lower-severity hypertension cases managed in the hospital. Correct classification affects Medicare inpatient reimbursement by grouping cases with comparable resource use and establishing the payment level for these admissions.
DRG 305 Overview
DRG 305 covers hospital admissions where the principal diagnosis is hypertension without a Major Complication or Comorbidity. It encompasses patients treated primarily for elevated blood pressure requiring inpatient management but without high-severity comorbid conditions that would escalate classification. This Diagnosis-Related Group matters for Medicare payment because it groups similar resource use and determines base reimbursement for these lower-severity hypertension admissions. Hospitals and coders must assign the correct principal diagnosis and document comorbidities to ensure accurate billing under Medicare rules.
