How to Complete the CMS/HCFA 1500 Claim Form for QMB (Qualified Medicare Beneficiary) Eligibility Only
If you are an Ambulance, Ambulatory Care Clinic, Advanced Nurse Practitioner, Optometrist, Physician, Podiatrist, or a provider serving a Qualified Medicare Beneficiary (QMB) patient, understanding how to accurately complete the CMS/HCFA 1500 claim form is essential. A Qualified Medicare Beneficiary (QMB) is an individual who qualifies for Medicare and also receives assistance from their state Medicaid program to pay for Medicare premiums, deductibles, and coinsurance. This guide provides detailed, box-by-box instructions specifically for billing services for QMB patients to ensure proper reimbursement for both covered and non-covered charges.
Throughout this guide, we refer to the Explanation of Medicare Benefits (EOMB), which is a statement from Medicare explaining what was paid on a claim, and the Explanation of Benefits (EOB), a similar document issued by other insurance companies detailing how a claim was processed and what was paid.
QMB Billing for Medicare Coinsurance and Deductibles
For claims involving Medicare coinsurance and deductible amounts for QMB-eligible patients, follow these specific instructions on the CMS/HCFA 1500 claim form:
| Box Number | Instruction | Notes/Explanation |
|---|---|---|
| Box 1 | Place an ‘X’ in the Medicare box. | This indicates Medicare as the primary payer and is crucial for proper processing. It replaces the ‘Y’ indicator previously used in Box 24J on older HCFA 1500 forms. |
| Box 24D | Enter the procedure codes and modifiers normally billed to the secondary payer (e.g., MaineCare). | Use the standard CPT/HCPCS codes and any necessary modifiers that would typically be billed to the state’s Medicaid program or other secondary insurance. |
| Box 24F | Charges must reflect the sum of the Medicare coinsurance and deductible amounts. | These amounts should be exactly as shown on the Explanation of Medicare Benefits (EOMB). For example, if the Medicare EOMB shows a $20 coinsurance and a $50 deductible for a service, enter $70 as the charge for that line item. |
| Box 28 | Enter the total charges. | This sum must precisely equal the total of all individual line item charges entered in Box 24F. For instance, if you have one line with $70 in 24F, Box 28 should show $70. |
| Box 29 | Enter any other third-party payments from an insurance company. | Do NOT include the Medicare payment amount here. Only payments received from other secondary or tertiary insurers should be entered. For instance, if a supplemental plan paid $10 towards the remaining balance, enter $10 here. |
| Box 30 | Enter the balance due. | This amount cannot exceed the member responsibility as indicated on the Explanation of Benefits (EOB) from the secondary payer. This is the amount still outstanding after all payments. |
Required Attachments: Always attach a copy of the Explanation of Medicare Benefits (EOMB) and any third-party Explanation of Benefits (EOB) relevant to the claim.
Important Rule: Do Not Combine Coinsurance/Deductible Charges with Medicare Non-Covered Charges!
It is absolutely critical to use one claim form for billing coinsurance/deductible charges and a separate claim for Medicare non-covered charges.
Combining these two distinct types of charges on a single CMS/HCFA 1500 form can lead to automatic claim denials, significant processing delays, and incorrect reimbursement. Each type of charge follows different billing rules and adjudication processes, necessitating separate submissions for proper handling by payers.
Handling Medicare Non-Covered Charges for QMB Patients
For services that are entirely non-covered by Medicare but may be covered by the QMB patient’s state Medicaid program or other secondary insurance, follow these instructions:
| Box Number | Instruction | Notes/Explanation |
|---|---|---|
| Box 1 | Do NOT place an ‘X’ in the Medicare box. | Since these specific services are entirely non-covered by Medicare, Medicare is not the payer. Mark the appropriate box for the primary payer (e.g., Medicaid). |
| Box 24F | Charges must reflect your full billed charges for the service. | Unlike coinsurance/deductible claims, here you enter the total amount you typically charge for the non-covered service. For example, if a service not covered by Medicare costs $150, enter $150 as the billed charge. |
| Box 29 | Enter any other third-party payments from an insurance company. | This box is for payments received from any other insurance plan that might cover the non-Medicare service, similar to Box 29 above. |
Required Attachments: Attach a copy of the Explanation of Medicare Benefits (EOMB) (if applicable, to show official non-coverage status) and any third-party Explanation of Benefits (EOB).
