How to work on Medicare denial - 22, 24 & 109
When working on these denials, it may create confusion sometimes because when you check eligibility on the Medicare portal or Medicare IVR, you find 2 options - MCO/HMO & MSP and it may be possible that the insurance is available in both tabs then it is difficult to find the correct primary insurance to bill the claim. This post will help to resolve the confusion. Please go through the complete post to have a clear understanding.
1. Denial 24 (Covered under managed care plan) & 109 (Not covered by this payer):
Scenario 1: On these denials, you need to refer to the MCO/HMO tab and the insurance available under this tab will be the primary insurance. After updating this insurance as primary, you do not need to keep the Medicare insurance as a secondary payer because the MCO/HMO plan pays on behalf of Medicare.
Scenario 2: On denial 109, there is another possibility that you will not find any insurance under the MCO/HMO tab. In that case, there may be a possibility of the patient enrolled in Railroad Medicare then you will need to submit the claim to Railroad Medicare (Palmetto Railroad) with the same policy ID.
2. Denial 22 (Other Payer Primary):
Scenario 1: On this denial, you need to refer to the MSP tab and the insurance available under this tab will be the primary insurance. Once you find the primary insurance information then update it as primary insurance and keep Medicare insurance as a secondary payer. Note: Whenever you are making Medicare as secondary, always update the MSP code. Please visit the below link to learn more about the MSP code,

Scenario 2: There is another possibility that you will not find any insurance under the MSP tab. In that case, you can resubmit the claim to Medicare.
Scenario 3: You may find multiple insurances in the MSP tab, in that case under each insurance name, you will find the MSP code of the insurance. This MSP code will help to identify insurance types.
MSP Codes:
12 - Commercial insurance with health coverage for beneficiary with age 65 or above
13 - Commercial insurance with Health coverage for End-Stage Renal Disease beneficiary
14 - Auto Insurance
15 - Worker Compensation
41 - Black Lung Insurance
43 - Commercial insurance with health coverage for beneficiary under age 65
47 - Liability Insurance
12 - Commercial insurance with health coverage for beneficiary with age 65 or above
13 - Commercial insurance with Health coverage for End-Stage Renal Disease beneficiary
14 - Auto Insurance
15 - Worker Compensation
41 - Black Lung Insurance
43 - Commercial insurance with health coverage for beneficiary under age 65
47 - Liability Insurance
Example - You find 2 insurances under the MSP tab with MSP code 12 (Commercial insurance) & 14 (Auto insurance). In that case, you will need to identify the service whether it is related to health coverage or Auto injury. If it is related to health coverage then you will need to make primary insurance to an insurance that has MSP code as 12 and keep Medicare as secondary with MSP code 12. In the same way, if the service is Auto related injury then you will need to make Auto insurance as primary which is mentioned with MSP code 14 and Medicare as secondary with MSP code 14.
3. Other Possible Scenarios:
Sometimes, while checking the eligibility you can find a scenario where insurance is available in both MCO/HMO & MSP tabs. In that case, identifying the correct primary and secondary insurance is a little bit tricky. The below examples will help to identify the correct primary and secondary insurance.
Example 1 - There is an insurance in the MSP tab with MSP code 43 (Commercial insurance) and another insurance is under the MCO/HMO tab.
In such a scenario, you can make the insurance as primary which is available under the MSP tab and keep the insurance on secondary position which is available under the MCO/HMO tab. (No need to update the MSP code, it is needed when the original Medicare is updated as secondary)
Example 2 - There is an insurance in the MSP tab with MSP code 15 (Worker Compensation) and another insurance is under the MCO/HMO tab.
In such a scenario, you need to identify whether a service is related to a work-related injury or not. If it is not then you do not need to bill the claim to WC, you can directly make the MCO/HMO plan as primary insurance. Do not need to keep Medicare as secondary and submit the claim to the MCO/HMO plan.
If the service is related to work-related injury then you can make WC as primary and keep the MCO/HMO plan as secondary and submit the claim to worker comp. (No need to update the MSP code, it is needed when the original Medicare is updated as secondary)
