Instructions for C-SNAP Registration

Each user must create his or her own unique C-SNAP User Login ID. Registration only takes minutes to complete. Simply follow these easy steps.

Step 1 - C-SNAP User Agreement

Click on the Provider Registration button. Read the C-SNAP User Agreement. If you choose to accept the user agreement, select the "I Accept" radio button then "Continue" to proceed to the next step in the registration process.

Step 2 - Registrant Information

First, enter your Medicare group provider information:

  • Provider Transaction Access Number (PTAN)
  • National Provider Identifier (NPI)
  • Provider Name
  • Taxpayer Identification Number (Tax ID)

Then, supply your personal contact information:

  • Your Name
  • Telephone Number
  • Email Address

Finally, create a unique:

  • C-SNAP User Login ID
  • "Forgot Password" Question and Answer

C-SNAP USER LOGIN IDS MUST NOT BE SHARED (one C-SNAP User Login ID must be created per user).

Step 3 - Location Access

In order to gain access to patient eligibility and claim status data, you must select the NPI(s) associated with the Tax ID you entered in Step 2 and with any other Tax ID(s) you may bill under. These access requests will be forwarded immediately for approval.

Step 4 - Immediate Access

Registration is now complete unless you choose to apply for immediate access which will only allow you to create your password and log into the C-SNAP Website (immediate access DOES NOT mean instant ability to view claim status and eligibility). If you bypass this step, a letter containing your password will be sent by postal mail to the address on file for the NPI you registered with.

Step 5 - Verification (Immediate Access Only)

Verification is accomplished using information on a remittance advice with an issue date of 14 - 90 days prior to today. The remittance advice information entered in this step must be billed under the initial NPI you entered in Step 2 of the registration process.

Enter one of the following criteria:

  • Medicare Number (HICN) and Date of Service
  • Check Number
  • Claim Number

Step 6 - Password Creation (Immediate Access Only)

After verification, you will create a personal password for your account. Once you have successfully completed this step, you may now access C-SNAP by logging in with your C-SNAP User Login ID and personal password.

Browser Requirements

WPS supports C-SNAP on Microsoft Internet Explorer. You can download the latest version from the Microsoft web site. C-SNAP should also work with other Internet browsers (such as Firefox, Opera, and Safari); however, WPS does not guarantee their compatibility with C-SNAP.

Session Time-outs

The C-SNAP Website automatically logs out users after 15 minutes of inactivity. This is a security measure to protect your account information. Click on any link or button to keep your session active.
