CO 249 Denial Code: Readmission Claim Denial Explained

Code 249 indicates that the claim was denied because it was identified as a readmission. This means the payer considers the service as a subsequent admission within a certain period after a previous discharge, which they don't reimburse separately. The claim will be marked with Group Code CO, meaning it's a contractual write-off.

Who Pays: Group Code Liability

With Group Code CO, the provider must write off the amount. This is a contractual obligation, so the patient cannot be billed for the denied amount under code 249.

Why Claims Get Code 249

  • The patient was readmitted to the hospital shortly after discharge, triggering the readmission flag.
  • The claim was submitted without addressing a prior related admission, leading to the readmission identification.
  • The hospital's internal system did not catch the readmission status before billing.
  • The payer's readmission policy criteria were met, but the claim was not bundled with the initial admission.
  • The claim was submitted without necessary documentation to justify the readmission.

How to Fix & Resubmit

  1. Review the patient's admission history to confirm if the readmission determination is accurate.
  2. Check the payer's readmission policy to understand the criteria and timeframes that apply.
  3. Gather documentation that may support the medical necessity of the readmission if applicable.
  4. Contact the payer for clarification or reconsideration if you believe the readmission determination is incorrect.
  5. If justified, submit an appeal with supporting documentation explaining why the readmission should be covered.

Corrected Claim or Appeal?

For code 249, a formal appeal is warranted if the readmission was medically necessary and not related to the initial admission. A corrected claim is not applicable since this is a contractual adjustment.

Preventing Future 249 Denials

  • Ensure thorough review of patient admission history before claim submission to identify potential readmissions.
  • Educate the billing team on payer-specific readmission policies and timeframes.
  • Implement a system alert for potential readmissions to be reviewed prior to claim submission.
  • Ensure documentation is complete and justifies the necessity of any readmissions before billing.
