- They still must submit a claim to Medicare when they give you Medicare-covered services. If they don’t submit the claim for these services, you should contact the company that handles Medicare claims for your State to file a complaint. You can call 1-800-MEDICARE (1-800-663-4227) for their telephone number. TTY users should call 1-877-486-2048. In the meantime, you might have to pay the entire charge at the time of service, and then submit your claim to Medicare to get paid back.
- They may charge you more than the Medicare-approved amount, but there is a limit called “the limiting charge.” They can only charge you 15% over the Medicare-approved amount (but may be lower in your state). The limiting charge applies only to certain services and doesn’t apply to some supplies and durable medical equipment.
