tax_sales_rate — From the state’s own Streamlined Sales Tax rate and boundary files (24 states: AR, GA, IA, IN, KS, KY, MI, MN, NC, ND, NE, NJ, NV, OH, OK, RI, SD, TN, UT, VT, WA, WI, WV, WY).
tax_sales_rate_batch — The same answer as tax.
hospital_prices — From the machine-readable standard-charge files hospitals must publish (45 CFR 180), parsed and normalized: for each hospital within the radius that posts the code, nearest first, the gross charge, the discounted cash price, the de-identified minimum and maximum, and every payer and plan’s negotiated dollar amount or percentage (with the v3.
hospital_compare — For each named hospital: whether it posts the code, and over its items for the code (only those without modifiers when it posts any, so a professional -26 or bilateral -50 line does not skew the row) nearest-rank statistics of its gross charges, discounted cash prices and negotiated dollar amounts across payers and plans, the range of negotiated percentages, the de-identified minimum and maximum, and the number of payers.
hospital_payers — Every payer’s negotiated dollar amounts for the code at the hospitals within the radius, grouped by canonical payer_id (the stable id behind the many ways hospitals write a payer’s name), plan type and methodology (a per diem and a case rate are never pooled): how many hospitals and rates, and nearest-rank statistics.
hospital_changes — Change records from diffing consecutive weekly builds: a hospital republishing its file (source raw_sha256), items and payer rates that appear, disappear or change price, a hospital’s status or file date changing, and the canonical payer of a payer/plan name changing.
