What MA107 means

Item 19 of the CMS-1500 (“Additional Claim Information”) is a small field, and Medicare’s paper claim rules limit how much can be put into it. MA107 says your paper claim had more than three separate data items in field 19. Because scanning and keying systems rely on a predictable structure, the extra entries cause the claim to fail processing.

Common causes

  • Several payer-required statements for different lines were combined in field 19.
  • Drug descriptions, dates, and identifiers were all entered for a multi-line claim.
  • Staff used field 19 for internal notes the payer does not need.

How to fix it

  1. Review what field 19 contains and remove anything the payer does not require.
  2. Split the claim if different services each need their own field 19 entries.
  3. Resubmit the corrected claim, or send it electronically if you are able to.

How to prevent it

  • Train staff on what belongs in field 19 for each service type.
  • Move remaining paper billing to electronic claims where possible.
  • For paper-specific rejections like this, see claim rejection vs. denial.

Codes that may appear with MA107

  • CO-16 (Claim/service lacks information or has submission/billing error(s).): A submission or billing error, specifically overcrowding in field 19.
  • MA108 (Paper claim contains more than one data item in field 23.): The similar limit for field 23, which allows only one data item.
  • MA69 (Missing/incomplete/invalid remarks.): Missing or invalid remarks, the opposite problem of too little information.

MA107 FAQ

What is field 19 used for?

Item 19 on the CMS-1500 is for additional claim information that payers request, such as specific statements, dates, or drug descriptions.

What if I need to report more than three items?

Prioritize what the payer requires for the services billed. Consider splitting the claim or submitting electronically, where the note field is handled differently.

Does MA107 apply to electronic claims?

The official text refers to paper claims. Electronic claims have their own field length limits.
