Medical Insurance Translation: EOBs, Denial Letters, Prior Authorizations and Appeals

Medical insurance translation turns the documents your health plan sends, such as Explanations of Benefits, denial letters, prior authorization decisions and appeal forms, into a language you read well, so you can understand a decision and respond on time. Many health plans must also offer language help with these notices. Heartland provides certified document translations for insurance paperwork in more than 350 languages.

Quick summary

• Insurance documents decide what you pay and what care is approved, so a misunderstanding can cost money or delay treatment.
• Under federal rules, many health plans must offer a phone line that helps in other languages and must translate claim and appeal notices on request in certain counties (45 CFR 147.136(e)).
• Health programs covered by Section 1557 must provide free, accurate and timely language assistance and use qualified translators (45 CFR 92.201).
• Ask your plan for help first. Use a professional translation when you need a full written copy for your records, an appeal or a provider.
• Check the appeal deadline in your notice before anything else.

Which insurance documents usually need translation?

The documents that most often need translation are the ones that explain a decision or ask you to act. These five come up most:

Document	What it tells you	Why it matters
Explanation of Benefits (EOB)	What the plan paid for a visit and what you may owe	It is not a bill, but it shows what you may owe
Denial letter (adverse benefit determination)	That a claim or service was not covered, and why	It usually sets the deadline for an appeal
Prior authorization decision	Whether the plan approved a test, drug or procedure before you get it	A denial can delay treatment
Appeal and grievance forms	How to ask the plan to reconsider	Errors or missing information can weaken an appeal
Itemized bills and medical records for a claim	The services billed and the clinical details	Plans may ask for English versions of records from another country

If you received care outside the United States, our guide to medical records translation explains how to prepare clinical records for an insurer.

What does a denial notice have to tell you?

A denial notice from a plan covered by the Affordable Care Act's claims and appeals rules must identify the claim, explain the reason for the denial and describe how to appeal. Under 45 CFR 147.136, the notice must include:

• information that identifies the claim, including the date of service, the health care provider and the claim amount, if applicable;
• the denial code and its meaning, and a description of the plan's standard, if any, used to deny the claim;
• a description of the internal appeal and external review processes, including how to start an appeal;
• contact information for any consumer assistance office or ombudsman that can help.

The same rule lets you ask for the diagnosis and treatment codes, and what they mean, behind the decision. Asking for those codes does not, by itself, count as filing an appeal.

These details are exactly what a translation needs to carry over accurately. A wrong date of service or a mistranslated denial reason can send an appeal in the wrong direction.

What language help must health plans provide?

Many health plans must provide language help with claim and appeal notices, but what they must provide depends on the type of plan and where you live. Three federal rules do most of the work.

ACA claims and appeals: the 10 percent county rule

For group health plans and individual health insurance covered by 45 CFR 147.136, notices must be provided "in a culturally and linguistically appropriate manner." In practice, the plan must:

1. offer oral language services, such as a phone hotline, that answer questions and help with claims and appeals in the applicable language;
2. provide, on request, a notice in that language; and
3. include a statement in that language in its English notices explaining how to get language help.

A language counts as "applicable" for an address when 10 percent or more of the people in that county are literate only in the same non-English language (45 CFR 147.136(e)). If your county does not meet that threshold, the plan may not be required to translate the notice itself, which is when a professional translation becomes useful.

Section 1557: meaningful access and qualified translators

Health programs and activities covered by Section 1557 of the Affordable Care Act must take reasonable steps to provide meaningful access to people with limited English proficiency. Language assistance must be free, accurate and timely, and when translation is required, the covered entity must use a qualified translator (45 CFR 92.201).

Covered entities must also tell people that free language help is available, in English and at least the 15 languages most commonly spoken by people with limited English proficiency in the state. That notice must go out with, among other documents, "notices of denial or termination of eligibility, benefits or services, including Explanations of Benefits, and notices of appeal and grievance rights" (45 CFR 92.11). Look for that notice, often a page of short statements in many languages, in the envelope with your EOB or denial letter.

Medicare Advantage: the 5 percent rule

Medicare Advantage plans must translate required materials into any non-English language that is the primary language of at least 5 percent of the people in the plan's service area. Once a plan knows a member's primary language, it must keep sending required materials in that language on a standing basis (42 CFR 422.2267(a)).

Can you rely on machine translation for insurance letters?

Machine translation can help you get the general idea of a letter, but it should not be the version you rely on for a decision about coverage or an appeal. Insurance letters mix legal terms, billing codes and medical vocabulary, and a small error can change what a sentence means.

Federal rules reflect this. Under Section 1557, when a covered entity uses machine translation for text that is "critical to the rights, benefits, or meaningful access" of a person with limited English proficiency, or where accuracy is essential, a qualified human translator must review it (45 CFR 92.201(c)(3)). A denial letter or appeal form fits that description.

How do you get an insurance document translated?

Start with your health plan, then use a professional translation for anything you need in writing that the plan does not provide.

1. Find the deadline. Look for the appeal or response deadline in the notice. Write it down before you do anything else.
2. Call the number on your card or notice. Ask for language help. Many plans can explain the letter by phone with an interpreter and send a translated notice on request.
3. Ask for the codes. If a claim was denied, ask for the diagnosis and treatment codes and their meanings, so the translation and your appeal work from complete information.
4. Gather every page. Include the envelope inserts, the EOB and any attached forms. Missing pages lead to missing context.
5. Order a translation of what you need in writing. Tell the translator who will read it (you, the plan, a provider or an attorney) and whether you need a certified translation with a statement of accuracy.
6. Keep copies. Save the original, the translation and notes from every call, including dates and names.

If you are writing an appeal in your own language, you may also need it translated into English before you send it. Ask the plan how it accepts appeals from members who don't write in English.

What should providers and employers do?

Clinics, hospitals, billing offices and employers that help people with their health benefits often see these documents first. The most useful steps are simple:

• Don't use family members or untrained staff to explain coverage decisions. Section 1557 limits relying on accompanying adults and minors to interpret, except in narrow situations (45 CFR 92.201(e)).
• Use a qualified interpreter for billing and benefits conversations. Heartland offers phone, video and on-site interpreting, available 24/7.
• Translate the forms you control. Financial assistance applications, payment plans and billing FAQs are good candidates for healthcare translation that stays consistent as your forms change.

Frequently asked questions

Is an Explanation of Benefits a bill?

No. An EOB explains what your plan paid for a service and what you may owe. Your provider sends the bill. Compare the two, and call your plan if they don't match.

Can my health plan translate my denial letter?

Sometimes. Many plans must offer oral language help with claims and appeals, and some must send a translated notice on request, depending on your plan type and county. Health programs covered by Section 1557 must provide language assistance free of charge. Call the member services number on your card or notice and ask.

Do I need a certified translation for an insurance appeal?

It depends on the plan. Some plans accept a standard translation, while others or an attorney may ask for a certified translation with a signed statement of accuracy. Ask the plan before you order, and keep the original documents.

How long does an insurance document translation take?

Turnaround depends on the length of the documents and the language. Share your appeal deadline when you request a quote so we can confirm timing before work starts.
