Reminder: New rejection codes for Medicare Advantage claims

On December 5, our claim processing system for Cigna Healthcare^® Medicare Advantage plans was updated to include new rejection codes. This may result in claim rejections due to mismatched customer information, such as a misspelled name.

You should review your claim submission rejection reasons and ensure the customer information on the claim matches the customer ID card and Real Time Eligibility.

Please resubmit claims with correct, matching customer information if you see one of the following rejection codes:

A3: Acknowledgement/Returned as un-processable claim (the claim/encounter has been rejected and has not been entered into the adjudication system)
31: Subscriber and policyholder name mismatched
IL: Insured or Subscriber
