Medicare Part B claims are billing records submitted by healthcare providers to Medicare for outpatient services like lab tests, imaging, and physician visits. Each claim includes CPT and diagnosis codes that describe exactly what medical procedure or test was performed. In the medical world, these claims are essential for reimbursement and compliance tracking.
For commercial and sales teams in diagnostics or biopharma, Medicare Part B claims data reveals which providers are actively performing certain tests — a signal of real buying intent. Since Part B covers fee-for-service patients (not Medicare Advantage), it offers a clear, nationwide view of provider activity. This makes Medicare Part B claims one of the most powerful datasets for identifying high-value leads in healthcare sales.
