ICD-10-CM, LOINC & Clinical Terminology Scraper

ICD-10-CM, LOINC & Clinical Terminology Scraper

Scrape ICD-10-CM, LOINC, RxTerms, and other clinical terminology tables from the NLM Clinical Tables API. Get diagnosis codes, lab observations, drug names, and procedure terms in a flat, ready-to-analyze format. No API key or registration required. Export to CSV, JSON, Excel, or XML.

The NLM Clinical Tables API is the authoritative source for U.S. clinical terminology, but querying it directly means handling pagination, rate limits, and nested JSON. This actor reads the public tables for ICD-10-CM diagnosis codes, LOINC lab observations, RxTerms drug names, disease names, conditions, and procedures, and returns each matching row in one fixed schema. Search by code or display name, or browse an entire table from the top.

Who uses it	What they scrape NLM Clinical Tables for
Health data analysts	Build clean reference datasets of diagnosis codes or lab observations for analytics.
EHR integration engineers	Pull current ICD-10-CM or LOINC codes to map clinical data in healthcare applications.
Clinical researchers	Gather standardized terminology for study protocols or data harmonization.
Medical billing specialists	Verify billable ICD-10-CM codes and their descriptions for claims.

What it does

This Actor collects rows from the NLM Clinical Tables API for the table you select, filtered by an optional search term, and returns each row as a flat record.

• 📋 Six clinical tables: ICD-10-CM diagnosis codes, LOINC lab observations, RxTerms drugs, disease names, conditions, and procedures.
• 🔍 Search or browse: Filter by code or display name, or leave the query empty to collect from the top of the table.
• 📄 Flat output: Every row is returned as a simple object with the table's native fields, ready for CSV or JSON export.
• ⚙️ Pagination control: Set the page size up to the NLM maximum of 500 rows per request and cap the total codes collected.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with NLM Clinical Tables data

Troubleshooting

Why am I getting no results?

Check your search term. The actor matches against both code and display name, but the term must be exact or a substring. Try a broader term or leave the query empty to browse the table.

The run stops before collecting all codes.

Verify the 'Maximum codes' setting. If it is lower than the number of matching rows, the actor stops early. Increase the maximum or remove the search term to collect more.

I get an error about page size.

The NLM API has a hard maximum of 500 rows per request. Set the 'Page Size' to 500 or less. The actor will paginate automatically.

The output has unexpected fields.

Each table returns its own set of fields. Check the table you selected and refer to the NLM Clinical Tables documentation for field definitions.
