CMS Open Data

Calculate fast published Medicare Part D national or statewide totals for an exact generic or brand name using CMS's preaggregated geography dataset. Returns only additive claims, standardized 30-day fills, and gross drug cost, with explicit small-cell suppression and completeness disclosures.

get_part_d_geography_totals

Compare published Medicare Part D totals for nurse practitioners versus an explicit CMS physician-specialty mapping for one exact generic or brand and optional state. The comparison is returned only after every matching published provider row is read through bounded pagination before the timeout; incomplete pages are never summed.

compare_part_d_prescriber_classes

Find or rank official Medicare Part D prescribing by public prescriber NPI, last/organization name, exact prescriber type, brand name, generic name, or state. Returns claim/fill counts, aggregate drug costs, suppression flags, exact official source queries, record keys, and reporting dates.

search_part_d_prescribers_by_drug

Inspect the live column schema for one curated CMS payment or utilization dataset and return its dataset-specific provenance.

Return independent bounded two-to-five-year national or state trends for one to three exact HCPCS/CPT codes. Never combines service totals across codes.

List the curated official CMS Part B, Part D, and inpatient hospital datasets supported by this connector, with current version and citation metadata.

Rank national or single-state Medicare physician HCPCS/CPT services by an explicit per-service or estimated-total charge/payment measure over a complete bounded population. Use for most/least expensive, highest/lowest cost, or top/bottom physician procedure and service questions.

Find or rank national or state-level Medicare physician HCPCS utilization, provider counts, charges, allowed amounts, and payments by state name or HCPCS code.

Find or rank official Medicare inpatient hospital discharges, covered charges, total payments, and Medicare payments by hospital CCN/name, DRG, or state, with the CMS small-cell exclusion and exact row provenance.

Find or rank provider-level Medicare physician utilization, submitted charges, allowed amounts, payments, and standardized amounts by NPI, provider last/organization name, or two-letter state.
