Doctor Prescribing Patterns (Medicare Part D)
Pricing
Pay per usage
Which doctors prescribe which drugs, and what Medicare paid: official CMS Part D prescriber data by drug, specialty, state or NPI, ranked by spend or claim volume, plus per-prescriber totals and national and state drug totals. No API key.
Prescribers by drug returns one row per doctor per drug, ranked - the flagship view. Provider totals returns one row per prescriber across every drug they wrote. Drug by geography returns national and per-state totals for a drug, with opioid and antibiotic flags.
Brand drug name, for example Ozempic, Eliquis, Humira. Must match exactly, though capitalization does not matter. If nothing matches, the run returns free suggestions of real names.
Generic ingredient name, for example Semaglutide, Apixaban. Exact match, capitalization does not matter.
Two letter state of the prescriber, for example TX or CA. In drug by geography mode this selects that state's totals instead of national.
Prescriber specialty exactly as CMS records it, for example Cardiology, Endocrinology, Family Practice, Internal Medicine.
Ten digit National Provider Identifier, to pull one specific prescriber. Optional.
Prescriber last name or organization name. Exact match, capitalization does not matter. Combine with state to narrow common names.
Which program year to read. CMS publishes about 18 months behind, so the newest complete year is the default.
Highest first. Total cost surfaces the biggest spenders, claims surfaces the highest volume prescribers.
