Q: We are receiving reject reason code 34538, so what steps can we take to avoid this reason code?
You can refer to Part A reason code lookup
for a description associated with the Medicare Part A reason code. Enter a valid reason code into the box and click the submit button.
A: You receive this reason code when the beneficiary or the spouse was or is working for the date(s) of service and the employer’s insurance is primary to Medicare.
There are several ways to confirm beneficiary eligibility:
• Note: Customer service representatives cannot assist you with eligibility information and are required by CMS to refer you to the IVR.
Obtain the beneficiary’s eligibility via the SPOT
• If the information is invalid
The provider or the beneficiary must contact the MSP Contractor
at 1-855-798-2627, to have the record updated. Once the record is updated, refile the claim to Medicare for primary payment consideration.
• If the information is valid
• File the claim to the primary insurance listed on the beneficiary’s records and then to Medicare for secondary payment consideration
