If you're in Original Medicare, doctors and suppliers are required by law to file Medicare claims for covered services and supplies you get. Find out which doctors in your area accept assignment.
If you have a Medicare Advantage Plan, these plans don’t have to file claims because Medicare pays these private insurance companies a set amount every month.
When Do I Need to File a Claim?
You should only need to file a claim in very rare cases.
Medicare claims must be filed no later than 12 months (or 1 full calendar year) after the date when the services were provided. If a claim isn't filed within this time limit, Medicare can't pay its share. For example, if you see your doctor on March 22, 2011, the Medicare claim for that visit must be filed no later than March 22, 2012. Check the MSN you get in the mail every 3 months to make sure claims are being filed timely. If the claims aren't being filed timely:
- Contact Your Doctor or Supplier and ask them to file a claim.
- If they don't file a claim, call 1-800-MEDICARE and ask for the exact time limit for filing a Medicare claim for the service or supply you got. If it's close to the end of the time limit and your doctor or supplier still hasn't filed the claim, you should file the claim.
How Do I File a Claim?
Print the Patient’s Request for Medical Payment form and follow the instructions to complete it.
If you want Medicare to give your personal health information to someone other than you, you need to let Medicare know in writing by filling out the Authorization to Disclose Personal Health Information form.
