Healthcare 50 HIPAA — Free Sample (5 records)
This is a free 5-record sample of the full 50-record commercial dataset. Every record in this sample is a real, valid healthcare record — real records, just the data. you'd build by hand.
What's in this sample
- 5 records in
records.jsonl(NDJSON, one record per line) - Schema-validated: every record parses against the real industry-standard schema before publishing
- Ready to use: import directly into any healthcare pipeline — no transformation step needed
- Format: standard JSON Lines (
.jsonl), healthcare-native structure
Why these records hold up
Most synthetic datasets are "good enough" — they look like the right shape, but fail against real-world parsers. Cottonwood Development's datasets are generated and validated against the actual schema:
- Healthcare records validate as valid FHIR R4
Patientresources - Banking messages parse against the ISO 20022
pacs.008.001.10XSD - CRM records maintain referential integrity (customer → orders → line items)
- Invoice records have internally-consistent totals (subtotal + tax = total)
Every record passes schema validation before publishing. If it doesn't parse against the real spec, it doesn't ship.
Sample record
{
"resourceType": "Patient",
"id": "12345",
"identifier": [
{
"system": "http://hospital.smarthealthit.org",

Schema
The full dataset uses the following field structure:
| Field | Type | Description |
|---|---|---|
resourceType |
string |
Always "Patient" — FHIR resource type |
id |
string |
Sequential record ID (e.g. "pat-000001") |
identifier |
array |
MRN + other IDs (system + value pairs) |
name |
array |
Patient names (family + given, with use flag) |
gender |
string |
"male", "female", or "other" |
birthDate |
string |
ISO 8601 date (YYYY-MM-DD) |
telecom |
array |
Phone, email contacts |
address |
array |
Mailing addresses (line, city, state, postalCode) |
Use cases
- Test fixtures for FHIR-based applications
- Demo data for healthcare platforms (EHR, patient portals)
- ETL pipeline testing — validate ingestion before real data lands
- ML training for clinical NLP, medical record extraction
- HIPAA-compliant development — no real PHI, no compliance overhead
