CMS-1490S: Patient's Request for Medical Payment
If you paid out-of-pocket for medical services and your doctor or supplier is unable (or refuses) to bill Medicare, you aren't out of luck. The CMS-1490S form is your direct path to claiming the reimbursement you are owed.
What Exactly Is the CMS-1490S?
The CMS-1490S is an official federal form used by Medicare beneficiaries to request direct reimbursement for covered medical services or supplies. Under normal circumstances, your healthcare provider submits claims directly to Medicare. However, the system isn't perfect, and sometimes the burden falls on the patient.
You will typically use this form in specific scenarios, such as:
- Receiving emergency care at a foreign hospital (in the rare cases Medicare covers it).
- Getting treated by a non-participating provider who refuses to file a claim on your behalf.
- Purchasing durable medical equipment from a supplier who does not submit Medicare claims.
Who Must File It?
This form is strictly for Medicare beneficiaries (or their authorized representatives). Medical providers cannot use the CMS-1490S to bill Medicare; they have their own specialized billing forms (like the CMS-1500).
Important Note: You should only file this form if your provider has explicitly stated they will not file a claim for you, or if they have missed the filing deadline. If your doctor is already processing the claim, filing the CMS-1490S will cause duplicate errors and delay your payment.
What You Need Before Starting
Medicare will reject your CMS-1490S if you do not attach the correct supporting documentation. Do not submit credit card receipts or standard cash register receipts—they are not enough. You must have an itemized bill from your doctor or supplier.
Required Information
- Your exact Medicare Number (from your red, white, and blue card)
- Your exact name as it appears on your card
- Description of your illness or injury
Itemized Bill Requirements
- Provider's name and address
- Date(s) of service
- Place of service (e.g., clinic, hospital)
- Specific description of each service/supply
- Charge for each individual item
- Diagnosis code (if available)
Detailed Form Walkthrough
The form is relatively short, but precision is critical. Here is how the sections break down:
1. Patient Information
You must enter your name, address, phone number, and Medicare number exactly as they appear on your official documents. Even a minor typo in your Medicare number will result in an automatic rejection.
2. Condition Details
You'll be asked to describe your illness or injury. Keep it concise but specific (e.g., "sprained left ankle" rather than just "hurt"). You also need to indicate if the condition is related to your employment or an auto accident, as this determines if Medicare is the primary or secondary payer.
3. Other Insurance
If you have a supplemental policy, Medicaid, or employer-sponsored health insurance, you must declare it here. Medicare coordinates benefits with other insurers.

Deadlines and Filing Rules
Medicare enforces a strict timely filing limit. You must file your CMS-1490S claim no later than one full calendar year following the year in which the services were provided. For example, if you received medical care on August 15, 2024, your claim must reach Medicare by December 31, 2025.
If you miss this window, Medicare will deny the claim, and you will be responsible for the entire bill. Always check with the Centers for Medicare & Medicaid Services (CMS) for the current year's deadline or any emergency extensions.
