Administrative diagnosis codes for heart failure in Medicare claims require ongoing evaluation due to varying accuracy and lack of clinical granularity.
In the United States, heart failure affects approximately 6.5 million adults and its prevalence is expected to increase with population aging. 1 Unfortunately, there are not yet standardized approaches to describe and track its epidemiological burden within the Medicare population. 1 Diagnosis codes within Medicare claims are often used to identify heart failure cases, clinical subtypes, and associated outcomes for purposes including population health management, reimbursement policy, and pharmacoepidemiologic research.2,3 Because the accuracy of administrative diagnosis codes may vary with clinical and policy conventions, their performance characteristics require ongoing evaluation.4 While clinical databases are not well-suited to describe national trends, national claims often lack the granularity to describe clinical and epidemiologic trends accurately.This challenge is common to other diseases and syndromes.
