Defense Submission Page
The Defense Submission page shows details about Part A claims and Part B claim lines included for a demand letter that are currently associated with the listed case.
From this page, you can view the case ID, demand letter ID, demand amount, demand letter date, and the date the MSP record was accepted by CMS. You can also view information for selected submitted defenses (see Notes) or begin the process of submitting a new defense for a claim or claim lines associated with the selected case. When submitting a new defense, you can select a claim or claim lines and choose a defense type to apply to it. You can also export the claim information on this page into a file to use outside of the CRCP.
Note:
- Claims previously submitted with a defense will only continue to display on this page if they are still associated to the case. Additionally, if the previous defense was approved, claims that were removed from the case will no longer be viewable on this page.
- Only one defense type can be applied per submission; however, you can make multiple submissions.
This page lists the following information for claims or claim lines:
- Select for Defense
Use these checkboxes to select claims individually, to select all claims or claim lines available for selection, or to deselect all claims currently selected.
Note: There is no limit the number of times that a claim or claim line actively associated to the case can be submitted for a defense. However, the claim or claim line cannot be submitted for defense if the Defense Decision Code column is set to "Pending Review". In this case, the Select for Defense checkbox is disabled. - Claim Control Number
The first eight characters are masked with an asterisk if you are not logged in using multi-factor authentication (MFA). - Claim Line Number ("0" is used for Part A claims)
- First Date of Service
Displays for MFA users only. - Last Date of Service

If a prior claim-level defense was submitted on the CRCP, "CRCP" and the defense submission date will be shown. If a defense was never submitted, this field will be blank. Otherwise, "Mail/Fax" is displayed. - Defense Decision Code

Displays up to three active values (separated with a semi-colon) for claims and claim lines previously submitted for defense that were denied by the CRC; otherwise, displays as blank.
Notes: Part A claims are shown first, followed by Part B claim lines. Rows are displayed in ascending order by the first date of service for Part A claims. For Part B claim lines, rows are shown in ascending order by the first date of service, and then by claim control number and claim line number. If more than one defense has been submitted for a claim or claim line, the most recent defense submission information will be shown.
You can hover over values in the Defense Type, Defense Decision Code, and Docs Needed for Defense columns to display their full descriptions.
You can sort the claims listed by all columns except the Claim Line Number, Defense Decision Code, and Docs Needed for Defense columns. You can filter the claims by the Claim Control Number (if you logged in using MFA), the Billed Amount, or the Defense Received columns.
Click Clear to remove any sorting or filtering selections and return to the initial table display.
Click Export to export the data to a file. Note: Data will not retain any user-applied sorting or filtering in the exported file.
To apply a defense to a claim or claim line:
- Select the checkbox next to one or more claim(s) or claim line(s) for which you want to submit a defense.
Note: Clicking the Select All/Deselect All checkbox selects all the available claims. Clicking this checkbox again will deselect all claims previously selected. - Select a defense type from the drop-down menu to apply the defense type to the selected claim or claim line(s).
Note: Once you apply a defense type to a claim or claim lines, you will only be able to apply the same defense type to other claims in the same defense submission. If you want to apply a different defense type, you can do so in another submission or you can select a different defense type and it will apply to all selected claims in this submission. - Click Continue to continue the defense submission process and navigate to the Defense Verification page or click Cancel to return to the Case Information page without submitting any changes for your defense.
