Use of the ICD-10 vision codes to study ocular conditions in Medicare beneficiaries with stroke.
The purpose of this study was to describe the use of ICD-10 vision codes in a large cohort of stroke survivors. Findings showed that ocular comorbidity was present in a portion of the studied stroke survivors, but the vision codes used to describe impairments in this population were few and lacked specificity. Recommendations included future studies to compare ophthalmic examination results with billing codes in order to characterize the type and frequency of ocular comorbidity.

Validity of claims-based stroke algorithms in contemporary Medicare data: reasons for geographic and racial differences in stroke (REGARDS) study linked with medicare claims.
The researchers assessed the validity of diagnostic coding algorithms for identifying stroke in the Medicare population by linking data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study to Medicare claims. They found that claims-based algorithms to identify stroke in a contemporary Medicare cohort had high positive predictive value and specificity, supporting their use as outcomes for etiologic and comparative effectiveness studies in similar populations.
