</Info>

## 1. Create your account

<Steps>
  <Step title="Sign up">
    Go to [app.denialbase.com/signup](https://app.denialbase.com/signup). Use your work email — personal email addresses get rate-limited during signup.
  </Step>

  <Step title="Verify email + enable 2FA">
    Click the verification link, then enable TOTP or a passkey. 2FA is required for all accounts that touch PHI.
  </Step>

  <Step title="Complete the onboarding wizard">
    Name your practice, choose your specialty, and confirm your first payer. You can edit all of this later in **Settings → Practice**.
  </Step>
</Steps>

## 2. Upload your first denial

<Tabs>
  <Tab title="EOB / ERA">
    Drag a PDF or image of the payer's Explanation of Benefits onto the upload zone. Supported formats: PDF, PNG, JPG, TIFF, and X12 835.
  </Tab>

  <Tab title="Denial letter">
    Written denial letters work too — upload the PDF and Denialbase will extract the denial reason, deadline, and appeal rights language.
  </Tab>

  <Tab title="API">
    ```bash theme={null}
    curl -X POST https://api.denialbase.com/api/v1/documents \
      -H "Cookie: $SESSION_COOKIE" \
      -F "file=@denial.pdf" \
      -F "document_type=eob"

## 3. Review the AI detection

Within \~30 seconds you'll see:

<AccordionGroup>
  <Accordion title="Denial reason" icon="magnifying-glass">
    Classified into one of 10 types: medical necessity, prior authorization, coding error, timely filing, out-of-network, coverage exclusion, coordination of benefits, patient responsibility, duplicate, or other.
  </Accordion>

  <Accordion title="Deadline" icon="clock">
    Extracted from the denial letter (plan-specific) and cross-checked against ERISA / state insurance law minimums.
  </Accordion>

  <Accordion title="Strategy recommendation" icon="lightbulb">
    Peer-to-peer, formal written appeal, or external review — with citations to the specific plan language and regulations.
  </Accordion>

  <Accordion title="Confidence score" icon="gauge">
    Below 70%? The denial is automatically routed to Human-in-the-Loop review before any appeal is drafted.
  </Accordion>
</AccordionGroup>

## 4. Generate and send the appeal

<Steps>
  <Step title="Review the draft">
    Denialbase pulls the patient's relevant medical records, drafts the appeal, and shows you a side-by-side with the denial.
  </Step>

  <Step title="Sign via DocuSeal">
    Your provider signs electronically. Signatures are audit-logged via a HIPAA-ready signature provider.
  </Step>

  <Step title="Submit">
    Send via the payer's preferred channel — portal upload, fax, or certified mail. Denialbase tracks the submission receipt.
  </Step>
</Steps>

<Check>
  That's it. The appeal is now in the **Tracking** view, where you'll get notifications for status changes and deadline warnings.
</Check>
