About this data. The prescription history for SAMANTHA MARIE HORN PA-C is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2024, the most recent federal release.

Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average among IN prescribers of the same medication and form, shown only when at least five prescribers contribute. Always confirm current medications and costs directly with the provider and your plan.
