# Interpreter Code of Ethics: Working Through Difficult Calls > Confidentiality, impartiality, accuracy: how to apply interpreter ethics without inventing rules or treating every setting as the same. Author: Mirkamol Published: April 1, 2026 Updated: September 8, 2026 Categories: Medical & Legal Canonical page: https://useinterpreter.com/blog/interpreter-code-of-ethics/ Don't take sides. Keep it confidential. Interpret accurately. You know the principles. A difficult call asks you to apply several at once. The provider keeps talking. The patient asks you a private question. You think a misunderstanding has slipped through. There is no pause button while you look up the right paragraph of the code. That is a reason to prepare, not a reason to reduce ethics to “never intervene.” This guide uses fictional call situations. It is professional discussion, not legal advice or a substitute for the rules governing your assignment. ## Two Codes to Know, Plus the Rules of Your Assignment The [NCIHC National Code of Ethics](https://www.ncihc.org/assets/Accessible-files/NCIHC%20National%20Code%20of%20Ethics%20accessible.pdf) addresses healthcare interpreting. Its principles include confidentiality, accuracy, impartiality, role boundaries, and carefully considered advocacy. The [NAJIT code](https://najit.org/wp-content/uploads/2016/09/NAJITCodeofEthicsFINAL.pdf) binds NAJIT members and is a useful judiciary reference. It addresses faithful rendering, conflicts, confidentiality, limits of practice, and reporting conditions that impede performance. Neither association document is a universal substitute for court rules, institutional procedures, or applicable law. Identify the setting and the rules before accepting the assignment. Do not carry a healthcare intervention script into a courtroom unchanged. ## Confidentiality: Clearer Than You Think (Mostly) A call can leave you shaken. You still need support. The question is how to get it without turning someone else's private experience into your debriefing material. Start with the agency's authorized support or supervision process. Ask what information may be shared and through which channel. Removing a name does not make a distinctive story anonymous, especially in a small language community. For an informal conversation, stay with your own feelings: “That assignment was hard, and I need some quiet.” Avoid the diagnosis, clinic, language, date, or family details that could point to a particular person. Do not promise that any single phrasing is automatically safe. Context matters. Our [HIPAA guide](/blog/hipaa-for-interpreters/) explains why disclosure permissions require more than a general commitment to discretion. ## Impartiality: The Principle Everyone Agrees With Until They're on the Call Imagine a patient says yes to a proposed procedure, then asks a question suggesting they may have understood something different. Interpret the question completely. Do not decide that their consent is valid or invalid yourself. If you observe a communication problem, identify it specifically. “Interpreter requests clarification of what ‘same day’ refers to” is more useful than diagnosing the patient's motives from their cultural background. The NCIHC code does not ban all advocacy. It permits carefully assessed action when a patient's health, well-being, or dignity is at risk and less intrusive steps have not resolved the problem. That is not permission to choose treatment for a patient. NCIHC's [closer look at advocacy](https://www.ncihc.org/assets/Accessible-files/NCIHC%20Interpreter%20Advocacy%20in%20Healthcare%20Encounters%20A%20Closer%20Look%20A25.pdf) is useful preparation for these decisions. Review the institution's escalation routes before you need one. An intervention should have an identifiable purpose. What did you observe? What risk or misunderstanding are you addressing? What is the least intrusive effective action? How will you make it clear that you are speaking as the interpreter? ### The Dilemmas That Need More Than a Slogan **The patient confides in you before the provider joins.** Do not promise secrecy you cannot honor. Explain your role and encourage the patient to raise the concern with the provider. Follow the applicable confidentiality and safety procedures. Do not assume every pre-session disclosure must automatically be announced to the next person who enters. Who was present, what was understood, and any safety or reporting obligations matter. Seek authorized guidance when the boundary is unclear. **The provider makes a culturally loaded assumption.** Preserve the message, but do not answer with a stereotype of your own. If clarification is needed, describe the particular communication problem and let the parties explain themselves. **A child has been interpreting before you arrive.** Take over the assigned professional interpreting role and follow the institution's language-access process. Questions about permitted exceptions or reporting belong with its responsible staff. **You disagree with medical advice.** Do not replace the provider's words with your recommendation. Distinguish disagreement from a specific safety concern, and use the institution's appropriate escalation process if that concern needs attention. **Side conversations happen.** Explain the interpreting arrangement to all parties. If overlapping speech or a missing speaker identity prevents accurate rendering, say so. Do not silently choose which remarks deserve to reach the other party. ## Accuracy: The Non-Negotiable That's Harder Than It Sounds Bad audio and long turns do not excuse invented words. They tell you what needs fixing before you continue. The [NCIHC standards of practice](https://www.ncihc.org/assets/Accessible-files/NCIHC%20National%20Standards%20of%20Practice%20Sept%202005%20accessible.pdf) cover managing communication, correcting errors, and making clarification transparent. Asking a speaker to pause can be part of doing the work accurately. Prepare short interventions you can deliver without a speech about your own performance: - “Interpreter requests repetition of the medication name.” - “Interpreter requests one speaker at a time.” - “Interpreter needs to correct the previous interpretation.” These are practice scripts, not quotations from a code. Adapt them to the assignment's protocol and make the intervention understandable to all parties. An approved transcript can be a second reference. It can also mishear a number or assign speech to the wrong speaker. Do not treat a caption as proof that you heard correctly, and do not use an outside tool without authorization. ## Professional Boundaries: Where Your Role Ends When someone asks for your opinion, return the question to the person whose role it concerns. “I can interpret that question to the provider” is often enough. When someone asks for a summary, clarify the task rather than silently omitting material. A request that changes your role should be explicit, permitted, and within your competence. For judiciary work, NAJIT's limits of practice prohibit giving parties advice or acting as their lawyer. The code also calls for bringing impediments such as fatigue or inability to hear to the court's attention. That distinction matters. Maintaining a boundary does not mean pretending the conditions are adequate. It means addressing the problem through the proper role and channel. ## Consequences Are Real, Even Without a Lawsuit An edited message or unauthorized disclosure can harm the people on the call and damage trust. It can also trigger an employer, client, certification, or legal process, depending on the facts and applicable rules. Do not predict that a provider “will only request another interpreter” or that a patient “will never contact a lawyer.” You cannot know. If an incident occurs, report it through the designated process and preserve information as instructed. If your agency asks for insurance or indemnity terms, read them separately from the ethics code. Our [interpreter liability guide](/blog/interpreter-insurance-liability-guide/) explains the questions to take to a broker or attorney. ## Ethics Isn't a Test You Pass Once Keep the governing code and escalation contacts accessible. Review difficult situations using fictionalized or properly authorized material, not recognizable patient stories. Review how you made the decision. Which principle was at stake? What did you actually hear? What alternatives were available? What would you do earlier next time? The goal is a decision you can explain. Then you take the next call with a clearer idea of where to pause, clarify, or ask for help. --- *Related reading:* - [HIPAA for Interpreters](/blog/hipaa-for-interpreters/) - [Clarification Scripts for OPI Interpreters](/blog/clarification-scripts-opi-interpreters/) - [Interpreter Burnout and OPI](/blog/interpreter-burnout-opi/)
