About this data. The prescription history for DR. ALLISON A KING MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release.

Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Pediatric Hematology-Oncology prescribing approach at this Saint Louis, MO practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among MO prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
