Frequently Asked Questions ​

Quick answers to common questions about EDI Paisan.

General ​

What is EDI Paisan? ​

EDI Paisan is a browser-based tool for viewing, inspecting, and transforming healthcare EDI files. It turns cryptic X12 data into human-readable information — no more counting tildes or memorizing segment codes.

What file types are supported? ​

Currently we support ANSI X12 healthcare transactions:

  • 837P — Professional claims
  • 837I — Institutional claims
  • 835 — Remittance advice (payment explanations)
  • 270 — Eligibility inquiries
  • 271 — Eligibility responses

We're actively expanding support. Have a format you need? Let us know.

Is EDI Paisan a desktop app or a web app? ​

EDI Paisan runs entirely in your web browser — no installation required. Just go to app.edipaisan.com and start using it.

Do I need to create an account? ​

Yes. You'll need to enter your email address and log in to access EDI Paisan. Creating a free account is quick — just enter your email and you're in. All Free tier features are available immediately after login.

What browsers are supported? ​

EDI Paisan works on all modern browsers:

  • Google Chrome (recommended)
  • Mozilla Firefox
  • Microsoft Edge
  • Apple Safari

We recommend Chrome for the best performance with large files.

Security & Privacy ​

Does my file get uploaded to your servers? ​

No. Your EDI files are processed entirely in your browser using WebAssembly technology. The file never leaves your machine — not even temporarily.

This is a core design principle, not just a feature. Healthcare data is sensitive, and we built EDI Paisan to never require access to it.

Is EDI Paisan HIPAA compliant? ​

Because your files never leave your browser, EDI Paisan itself doesn't create HIPAA obligations — we never access, store, or transmit your PHI.

That said, you're still responsible for:

  • Using EDI Paisan on appropriate devices
  • Following your organization's policies
  • Not sharing screenshots containing PHI

For Enterprise customers who need formal documentation, we offer a Business Associate Agreement (BAA) that covers our cloud services (account management, etc.) even though your EDI data stays local.

Can Paisan AI see my data? ​

No. We have no access to the files you view in EDI Paisan. Our servers never receive your EDI data.

What we can see (for paid tiers):

  • Account information (email, name)
  • Usage statistics (files opened, features used — not file contents)
  • Crash reports (if you opt in)

What happens if I close the browser? ​

Your file is gone. Since nothing is stored on our servers, closing the browser (or refreshing the page) clears everything. You'll need to re-upload the file to view it again.

Pro Tip

Keep your source files organized locally. EDI Paisan is a viewer, not a storage solution.

Is my connection encrypted? ​

Yes. EDI Paisan uses HTTPS for all connections. However, since your files never leave your browser, encryption in transit isn't even needed for your EDI data — it simply doesn't travel.

Do you offer discounts for non-profits? ​

Yes! Healthcare non-profits and educational institutions can receive 30% off any paid tier. Contact us with details about your organization.

Yes — contact us to request a free Pro trial. We'll set you up so you can explore all Pro features before committing.

What's the cancellation policy? ​

Cancel anytime. No questions, no hassle. If you cancel mid-billing period, you'll retain access until the period ends.

Do you offer refunds? ​

Yes, for annual plans we offer a 30-day money-back guarantee. If Pro isn't right for you within the first 30 days, we'll refund your purchase in full.

Features ​

Can I edit EDI files in EDI Paisan? ​

Currently, EDI Paisan is focused on viewing and analyzing EDI files. While you can:

  • Split files (Pro)
  • Anonymize PHI (Pro)
  • Export data (Pro)

Full editing capabilities (creating or modifying transactions) are on our roadmap but not yet available.

What's claim splitting? ​

Claim splitting takes a batch file containing multiple claims and separates them into individual files. Useful for:

  • Isolating problem claims
  • Testing with single-claim files
  • Sharing specific claims without exposing the entire batch

What's PHI anonymization? ​

PHI anonymization replaces Protected Health Information with fake but realistic data. The file structure stays intact, but patient names, IDs, dates, and other identifiers are replaced. Perfect for:

  • Training new staff
  • Creating test files for developers
  • Sharing examples without privacy concerns

Can I export data to Excel? ​

Yes! Pro and Enterprise users can export to CSV (opens in Excel), Excel (.xlsx), and JSON formats. Choose which segments and elements to include.

Does EDI Paisan validate files? ​

EDI Paisan checks structural validity (proper envelope structure, segment formatting), but it doesn't perform full compliance validation against implementation guides. For compliance checking, you'd still need a dedicated EDI validator.

We highlight obvious structural issues, but passing EDI Paisan's parser doesn't guarantee your file will pass a clearinghouse or payer's validation.

Technical ​

What's the maximum file size? ​

100MB per file. This covers the vast majority of EDI files — even large batch files from busy providers.

For truly massive files (rare in healthcare EDI), consider splitting them before upload.

Why does a large file take a while to load? ​

Parsing happens entirely in your browser using WebAssembly. While this is fast (usually under a second), very large files require:

  1. Reading into browser memory
  2. Parsing delimiters
  3. Building the segment tree
  4. Loading element descriptions

For 50MB+ files, this might take a few seconds. Once loaded, navigation is instant.

Can I use EDI Paisan offline? ​

Not currently. While processing happens locally, you need an internet connection to load the app. Offline support (via a Progressive Web App) is on our roadmap.

Does EDI Paisan support EDIFACT? ​

No. EDI Paisan is focused on ANSI X12, the standard used in US healthcare. EDIFACT (used more in international trade and non-US healthcare) is not currently supported.

Does EDI Paisan support HL7? ​

No. HL7 (Health Level 7) is a different standard used for clinical data interchange. EDI Paisan is focused on X12 administrative transactions (claims, remittances, eligibility).

Why can't EDI Paisan parse my file? ​

Common reasons:

  • Not X12 format — File might be EDIFACT, HL7, or proprietary
  • Encrypted/compressed — Unzip or decrypt first
  • Truncated — File was cut off (missing IEA trailer)
  • Exotic delimiters — We support most, but some legacy systems use unusual characters

Open the file in a text editor. Valid X12 files start with ISA and end with IEA~.

Troubleshooting ​

The page is blank or won't load ​

Try:

  1. Clear browser cache and cookies
  2. Disable browser extensions (especially ad blockers)
  3. Try a different browser
  4. Check if JavaScript is enabled

My file shows "parsing error" ​

  • Verify the file is ANSI X12 format
  • Check the file isn't encrypted or compressed
  • Ensure the file is complete (has ISA at start, IEA at end)
  • Try opening in a text editor to verify content

Search isn't finding something I know is there ​

  • Search is case-insensitive, but exact
  • Try searching for partial terms
  • Check for leading/trailing spaces in your search
  • Make sure you're searching the right file (if multiple are loaded)

The app is running slowly ​

  • Close other browser tabs
  • Try Chrome if using another browser
  • Clear browser cache
  • For very large files, expect some initial parsing time

I lost my file after refreshing ​

This is expected. EDI Paisan doesn't store files — refresh clears everything. Keep your source files organized locally and re-upload as needed.
