CONTENTS
sample.csv: 100 real rows, all 123 columns from hospitals_full.csv.
Repeatable selection; not a statistically representative sample. The legend describes the full product; companion data tables are only in the full download.

FEATURES AND PREPARATION
- Every published Hospital General Information column, with CMS "Not Available" values kept blank beside explicit missing-value reasons and the original footnote codes.
- Medicare enrollment links by CCN with legal business name, NPI and PAC ID, plus owner and manager relationship counts on each hospital row.
- Every published hospital enrollment and owner or managing relationship, with roles, association dates, ownership percentages and owner organization types.
- Medicare cost reports from the two latest CMS public use fiscal years: every published report with beds, Medicare and Medicaid days, discharges, FTEs, costs, revenue, income, balance sheet and uncompensated care, plus HCRIS report status and dates; each hospital carries its most recent report by exact CCN.
- Footnote lookup table, +1 E.164 hospital phones, formatted ZIP codes, ISO dates and true/false flags.
- Current place links by labeled exact-key rules, with website, phone, shared-mailbox email, category, brand, social profiles and per-place attribution evidence.

USING THE FILES
legend.csv defines the columns, units, formats and blank-value meanings.
CSV is UTF-8 with headers. Import identifiers, ZIP codes and phones as text. Blank differs from zero or false.
Columns of type json contain JSON text within CSV cells.
LICENSES.txt contains source attribution and applicable notices.

LIMITATIONS
- Owner rows are relationships by role (owners, directors, officers and managing employees); one person or company can appear many times, and counts are not unique owners.
- Ownership percentages are self-reported to CMS; do not sum direct and indirect interests or assume they total 100%.
- Some enrollment CCNs, ZIP codes and PAC IDs lost leading zeros at the source. They are not padded; a five-digit CCN is linked only when the zero-restored CCN is a hospital in the same state.
- Enrollments also cover rehabilitation, long-term care and other hospitals and units absent from Hospital General Information; hospitals without a linked enrollment, such as federal hospitals, have blank ownership counts.
- Individual owners and managers are named as published by CMS, without personal contact details. A hospital phone is a facility number, not an owner contact; contacts are not reachability-verified.
- Star ratings and measure counts follow CMS reporting periods; "Not Available" means CMS published no value, not zero.
- Current place data are dated separately from the CMS editions; place coordinates are bounding-box minima.
- Cost report values are as published in the CMS public use files, which reflect HCRIS data as of the extract date CMS states; report status and dates come from later HCRIS files and can describe a reprocessed record of the same period (hcris_link_status).
- Cost report fiscal years follow the federal fiscal year in which each reporting period begins, so periods and end dates vary by hospital; most recent means the latest reporting period end date, then the later HCRIS receipt date.
- Cost reports link to hospitals only by identical six-character CCN. Hospitals without a captured report, such as federal hospitals, have blank cost report values; reports for CCNs outside Hospital General Information stay in cost_reports.csv.
- Medicare and Medicaid day shares are computed only from days published in the same report and are not imputed; blank cost report amounts are unknown, not zero.
- 77 source record(s): CCN is not six characters; retained as published and not linked
- 5 source record(s): Date 1800-01-01 may be a placeholder; retained as published
- 2 source record(s): Date is later than the source publication date; retained as published
- 803 source record(s): Five-digit CCN linked by restoring one leading zero (same practice-location state)
- 131 source record(s): Five-digit CCN; no same-state hospital has the zero-restored CCN; not linked
- 13 source record(s): Inverted question mark may replace a character the publisher could not encode; retained as published
- 1 source record(s): Published telephone number is not a valid NANP number; phone_e164 left blank
- 1502 source record(s): ZIP has neither 5 nor 9 digits; leading zeros may have been dropped at the source and are not restored
