If you think the information in your medical or billing record is incorrect, you can request that the health care provider or health plan amend the record. The health care provider or health plan must respond to your request. If it created the information, it must amend the information if it is inaccurate or incomplete. If the provider or plan does not agree to your request, you have the right to submit a statement of disagreement that the provider or plan must add to your record.
