Administrative Claims Databases

Claims systems are an important source for service utilization data, offering large sample sizes across a geographically dispersed population, identifiable at the state, county, and postal zip code level. Health insurance claims databases may also capture eye care services provided outside the scope of ophthalmology and optometry, such as services provided by general practitioners, pediatricians, and other specialists, or services provided in emergency department or inpatients settings. However, a fundamental limitation of claims data is that these are principally payment records and are based on diagnostic coding that may be driven by reimbursement concerns, thus may or may not always accurately reflect the true medical condition. For more information, please visit the Review of Claims and Registries Report Cdc-pdf[PDF – 870 KB]External.
