If your care was within a hospital, you should also file a complaint with the hospital's peer review committee, which has the power to revoke or limit a doctor's privileges to practice there. Call the agency you have found to inquire about how to file a formal complaint. Some agencies have toll-free hotlines for complaints. Others require complaints to be filed on a specific form. Ask whether your complaint will remain confidential.
State laws vary.
If the agency intends to reveal your name to your doctor, you may want to consider switching to another physician before pursuing any action. File a written complaint containing as much information as possible. Make sure to include the doctor's full name, correctly spelled, office address, and the exact date when the conduct you are complaining of occurred. The state may also ask you to release your medical records for review. Ask the agency to notify you of the outcome of your complaint.
