What it's actually for

Built for the documents medical billers actually work with.

Kadendoc was built around the specific paperwork billing teams push through every day.

Billing professional reviewing paperwork
Provider Appeal Form
Appeal Forms

Place fillable text fields and checkboxes directly onto any provider appeal form — including forms that were never made fillable to begin with.

Explanation of Benefits
EOBs & Remits

Cover or remove sensitive member information before forwarding an EOB internally.

Clinical notes documentation
Medical records and other documents

Merge a denial letter, the original claim, and supporting documentation into a single file, in the right order, in seconds — no separate merge tool, no upload.

Tools

Everything a billing team actually needs from a PDF tool.

No subscription, no watermarks, no "upgrade to unlock." See the full features list for the complete picture.

Fill in any form

Type directly onto blank lines, auto-shrink to fit, download — even on forms that were never made fillable.

Highlight & redact

True redaction flattens the page so removed text is genuinely gone, not just covered up.

Build fillable forms

Real text fields, checkboxes, radio groups, dropdowns — save the editable form you created for future use.

Merge & split

Combine claim documents into one file, or split a multi-page PDF apart, in seconds.

Draw & annotate

Freehand, shapes, arrows — circle the line item that matters, point at the denial code.

Handles big files

Multi-hundred-page PDFs render smoothly, page by page.

The paperwork never ends. The chaos can.

EOBs, patient statements, claims, denials, takeback letters from insurance — the pile grows every day. In medical billing, you can't stop the paperwork, but with Kadendoc, you can manage the mess. We are the single PDF platform that unifies and accelerates the unique administrative tasks medical billers face, turning overwhelming paper chaos into organized data flow.

Save time on document editing with 10 Plus Appeal Templates, 20+ editing tools, One workspace.

Time is quite literally money in billing. Every minute spent manually formatting an EOB or editing a PDF is a minute delayed on reimbursement. Kadendoc turns hours of manual administrative labor into a few clean clicks, with all the required tools in one workspace!

Your PHI stays under your control.

Kadendoc is a privacy-focused application with client-side processing and zero server storage.

Kadendoc is built with a client-side architecture. This means the tool and all the functions required to edit a document run entirely within your web browser using JavaScript, ensuring ultimate privacy for your daily workflows:

  • Local Processing: Your PDFs, EOBs, and patient records, etc. are processed entirely on your computer.
  • Zero Cloud Risk: Whether you're merging files, extracting data, or redacting text, every action happens inside your browser. No cloud uploads, no data transmission, and zero risk of a server breach.
  • Total Privacy: Kadendoc has zero access to the data you work on, as it has no storage (database) or server.

You handle the compliance; we provide the tool.

Why billers choose Kadendoc

Other PDF tools weren't made for this work.

General-purpose PDF tools are great for everyday use. But billing teams end up hitting page limits, waiting on uploads, and handing patient data to a server somewhere just to merge two pages together.

Kadendoc was built around the documents billing teams actually deal with — appeal forms, EOBs, claim files, authorizations, all of it carrying sensitive patient information. Everything runs in your browser, so there's nothing to install, no account to create, no file size cap on a busy day, and no patient data that ever has to leave your machine.

Questions people actually ask before trying it.

Is it actually free?+

Yes — Kadendoc is a free contribution to the billing community, so there's no paid tier. No trial that expires, no card required to keep using it next month.

Does it work on a form that's just scanned pages?+

Yes — it also lets you search, select, and copy the text, not just view it as a flat picture.

What happens to my file after I close the tab?+

Nothing — there was never a server copy to begin with. Closing the tab is effectively the same as deleting it.

Do I need to install anything?+

No. It's a website — open it, make the edit, close the tab when you're done.
