Why the study?
Do ICD-10 diagnosis codes accurately identify acute heart failure hospitalization and differentiate HFrEF from HFpEF in a national Medicare sample?

ICD-10 codes are valid and reliable tools for identifying acute heart failure hospitalizations and differentiating between HFrEF and HFpEF in Medicare claims data.
Answers are grounded in this paper and cite their sources.
Supports ICD-10-based HF identification in Medicare claims; extends validation to national sample for HFrEF/HFpEF differentiation.
ICD-10 principal diagnosis identified acute HF hospitalization with a high positive predictive value. Systolic and diastolic ICD-10 diagnoses reliably identified heart failure with reduced ejection fraction and HFpEF when EF 50% was used as the cutoff.
