Will insurance pay for root-canal treatment? Is it covered by National Health Insurance? — National Health Insurance follows the current notice; private insurance follows your policy terms

Direct answer (60 characters or fewer in the source language)

National Health Insurance coverage follows the National Health Insurance Administration's current notices; you can check the current covered-items list yourself ¹²³. Private insurance depends on the policy terms; ask the insurer that underwrote the policy ³⁰. This site makes no coverage decision and gives no claim opinion.

This guide is specific to Taiwan's healthcare system (National Health Insurance and Taiwan's Medical Care Act). The institutional and verification passages cite Taiwan statutes, competent-authority notices, and public statistics from an institution established by law (facts tagged geo: TW); evidence on root-canal procedures and risk cites international literature (tagged geo: universal). Taiwan's Medical Care Act is the law meant throughout this guide; its official English text is https://law.moj.gov.tw/ENG/LawClass/LawAll.aspx?pcode=L0020021 .

First split the route: which kind of “insurance” do you mean?

The one word “insurance” hides two questions assessed in wholly different ways ³⁰:

1. National Health Insurance (statutory insurance): covered items and payment standards have a statutory process for drafting and publication. Everyone uses the same publicly checkable rules ¹.
2. Private insurance (an insurance contract): the terms are in your own policy, and each person may hold a different policy ³⁰.

This article can take the first route through its verification steps; on the second route it only describes what you can do yourself. It does not decide whether any policy pays, interpret policy wording, compare insurers, or cite an individual claim outcome ³⁰.

How this article divides work with related cards

Why this tooth needs root-canal treatment, how many visits it takes, and how long post-treatment pain lasts are covered by the root-canal basics card. What makes up fees and what additional charges for microscopic root-canal treatment buy are covered by the root-canal cost card. The implant-insurance card uses the same boundaries for the insurance section. This article does not repeat those subjects; it only states what is needed here and links to the related card ³⁰.

The National Health Insurance side: what you can check and how

What this article does not do: it does not decide whether any item in any individual case is covered by National Health Insurance. Payment items are set out in payment standards approved and issued by the competent authority, may change with notices, and whether they apply to your tooth also depends on clinical conditions ¹². What this article can give you is a route you can follow yourself.

How payment standards are made

• Article 41 of Taiwan's National Health Insurance Act provides that medical-service payment items and payment standards are jointly drafted by the insurer and representatives of relevant agencies, experts and scholars, insured persons, employers, and contracted providers, then submitted to the competent authority for approval and publication ¹. Therefore, the current payment standards announced by the National Health Insurance Administration control both which items are covered and under what conditions ¹².
• Article 51 lists items outside the benefit scope. Two clauses directly relevant here are clause 10, “patient transportation, registration and supporting documents” ⁴, and clause 11, “dentures, artificial eyes, eyeglasses, hearing aids, wheelchairs, crutches and other appliances not of a positive therapeutic nature” ⁵. Listing those provisions is not a conclusion about the individual items in your treatment; this article makes no subsumption decision ⁴⁵.

Three routes you can use yourself

1. The National Health Insurance Administration's current-notice page: it maintains a “National Health Insurance Medical Service Payment Items and Payment Standards” page. On 2026-08-06 this article loaded the page in a browser; its files included “Payment Standards compressed file (NHI Fee Schedule) (.doc) (effective 115.07.01)” and “Medical-service payment items (CSV files may be downloaded from the open-data platform from 114.08.11)” ². Notices change, so use what you see on the day you check ².
2. For the item-by-item list, download the open data: the government open-data platform provides the National Health Insurance Administration dataset “Medical Service Payment Items and Payment Standards (CSV)” (dataset 174450). Its main fields include procedure code, NHI payment points, effective start and end dates, English item name, Chinese item name, and notes; it is updated every 1 day ³. Search the Chinese item name to see whether a procedure appears in the current list. Appearing in the list and applying to your own tooth are different questions; ask the treating institution to explain the latter under current rules and your clinical condition ³¹.
3. For self-paid fees, return to the county or city where you receive care: Article 21 of Taiwan's Medical Care Act provides that medical-fee standards charged by medical institutions are approved by the municipal or county (city) competent authority ⁶. One checked example is the Taipei City Department of Health's “Taipei City Medical Institution Dental Fee Schedule” (approved 1090117), also available as open-data dataset 121913, “Taipei City Medical Fee Standards,” provided by that department ¹³. For another county or city, look for the comparable notice published by its health bureau ⁶¹³.

⚠️ A known verification trap: neither classification route in the National Health Insurance Administration's Medical Device Price Comparison Network includes dentistry; it cannot be used to verify self-paid dental items. Be cautious of claims that dental prices can be checked there ¹⁴.

Receipts are documents you can reconcile yourself

Under Article 22 of Taiwan's Medical Care Act, when a medical institution collects medical fees it must issue a receipt showing the charge items and amounts; it must not violate the fee standard or overcharge or create an unauthorized charge item ⁷. If the treatment is charged in stages, keep the receipt from every stage. This returns in the next section because the receipt is both a reconciliation tool and an original document in your possession ³⁰.

Private insurance: where this site draws the line

This site's sole answer to this category is: it depends on the policy terms; ask the insurer that underwrote the policy [F30]. It does not interpret terms, judge individual cases, compare insurers, cite claim outcomes, or say “it should pay” or “it should not pay” ³⁰. The following stays within two limits: it records that issues exist without judging them, and states what you can prepare yourself.

“Surgical classification” is a named category in official statistics

This is not internet hearsay; it appears in public statistics. The Financial Ombudsman Institution was established with government funding under the Financial Consumer Protection Act to establish a financial-consumer dispute-resolution mechanism ¹⁵. It publishes quarterly statistics on categories of complaints and applications for review. In its “115Q1 Life Insurance Industry—Claim Complaint Case Dispute-Type Statistics,” covering 2026/1/1 to 2026/3/31, there are 21 categories including “other” and 1,281 cases in total; “surgical classification” accounts for 101 cases (7.88%), and “claim documents / medical-document classification” for 61 cases (4.76%) ¹⁶.

Those figures have only one use here: they show that the two issues exist and are classified in official statistics. They do not establish anything else ¹⁶³⁰:

• The population is all life insurers and all medical items, not a dental or root-canal subset ¹⁶.
• These are complaint-case categories, not dispute outcomes and not a statement that any individual was right or wrong ¹⁶.
• This site gives no opinion on any case, term, or company ³⁰.

Why “microscopic root-canal treatment” cannot establish the procedure category

This is one medical point the card can make clear, and one that often confuses people searching this topic.

• In the literature, endodontic treatment is divided into non-surgical and surgical procedures, with a clear boundary ¹⁸¹⁹. A Cochrane review defines root-canal retreatment as a non-surgical procedure: old root-canal filling material is removed and the canals are cleaned, shaped, and obturated. It defines root-end resection as a surgical procedure: an osteotomy exposes the periapical lesion, the lesion is surgically removed, part of the root tip is removed, and the remaining canal is disinfected and commonly retrograde sealed or filled ¹⁸.
• “Microscopic” describes magnification equipment, not a procedure category. Comparative studies of magnification devices exist only in the surgical context. All three prospective studies included in one systematic review concerned endodontic surgery; it found no outcome difference among loupes, surgical microscopes, and endoscopes, and found no comparative magnification-device studies for orthograde (non-surgical) endodontic treatment ¹⁹. In the literature, “endodontic microsurgery” is root-end surgery using the same instruments and materials but high-power magnification from a surgical microscope or endoscope ²¹.
• The evidence point: the current Cochrane review found no trial eligible for inclusion and says the effect of magnification-device type on treatment outcome is unknown ²⁰. Thus use of a microscope is neither a procedure category nor an efficacy criterion ¹⁹²⁰.

The practical reading is therefore: the procedure you actually receive is named in the treatment plan, record, and receipt; how a policy defines “surgery” is written in your policy terms. They are separate documents made by different people under different rules, and this site does not connect them ³⁰. “Surgical/non-surgical” in the literature is a clinical classification, not a determination of any insurance-contract terminology ¹⁸³⁰.

Article 63 of Taiwan's Medical Care Act separately requires an institution performing surgery to explain the reason, surgical success rate or possible complications and risks, obtain consent, and have surgery and anesthesia consent forms signed ⁸. That is an institutional duty under Taiwan law; it does not define the word “surgery” in any policy ⁸³⁰.

What about reimbursement-type policy questions?

A material share of the queries behind this topic asks about reimbursement-type policies ²⁹. The answer remains: it depends on the policy terms; ask the insurer that underwrote the policy [F30]. The only document-related fact to add is that official statistics list “claim documents / medical-document classification” as a claim-complaint category ¹⁶. Keeping every document is the part you control; this site does not interpret the terms or how an insurer will classify documents ³⁰.

What you can confirm yourself: ask the insurer before scheduling treatment

• Copy the procedure name from the treatment plan (for example, “root-canal treatment,” “root-canal retreatment,” “root-end surgery,” or “crown”) and ask the insurer's customer service or your insurance agent, not the dentist, about that name ³⁰.
• The dentist is responsible for diagnosis, treatment, and medical-record entries. For claim-related determinations, rely on the insurer's response; a verbal statement in the dental clinic does not replace policy terms ³⁰.
• To check what policies you hold or product information, the Taiwan Insurance Institute has a policy-product search page where product names can be searched by company category, company name, and keywords ¹⁷.
• Financial-consumer disputes also have the Financial Ombudsman Institution as a dispute-resolution mechanism established with government funding under the Financial Consumer Protection Act ¹⁵. This site does not decide any case or give a claim opinion ³⁰.

Treatment may be split into stages, and the documents are split with it

Root-canal treatment may not end with one visit and one receipt. That directly affects the documents you hold:

• It may be completed in one visit or in two or more. The current Cochrane review defines a single visit as completing root-canal obturation immediately after instrumentation and irrigation, and multiple visits as completion in two or more sessions with obturation at the final session ²². It included 47 studies, 5,805 participants, and 5,693 teeth analysed, and found no evidence that either schedule is more effective ²². Your dentist must decide which arrangement fits your condition.
• Repair follows treatment. A Cochrane review explains that endodontic treatment removes dental pulp and replaces it with root-canal filling. Root-filled teeth differ structurally from vital teeth, making restoration challenging; the restoration choice depends on remaining tooth structure and may affect durability and cost ²³. The review found insufficient evidence to assess differences between crowns and conventional fillings for restoring root-filled teeth ²³. The important point here is that this is a separate set of items and a separate set of receipts.
• There can also be later treatment. If initial treatment does not meet expectations, there can be non-surgical retreatment or a surgical route. The current Cochrane review found no clear superiority of surgical or non-surgical treatment at one-year follow-up and concluded that current evidence cannot provide reliable clinical guidance ¹⁸. Such events may occur much later ²⁶.

A workable approach (this site's organizational framework, not any institution's rule): make a simple treatment timeline yourself. For every visit, note the date, procedure name, and which document you received. Only you can make this complete record because the documents are inherently dispersed across visits ³⁰.

Documents you can obtain under Taiwan's system

The following are written in Taiwan's statutes. This section only states routes to obtain documents; it does not make any claim determination ³⁰:

• Receipt: Article 22 of Taiwan's Medical Care Act requires a receipt identifying charge items and amounts, and prohibits violating the fee standard, overcharging, or creating an unauthorized charge item ⁷.
• Surgery and anesthesia consent forms: Article 63 of Taiwan's Medical Care Act requires explanation and consent before an institution performs surgery ⁸.
• Information about your condition and treatment plan: Article 81 of Taiwan's Medical Care Act requires the institution to tell a patient about the condition, treatment plan, procedures, medication, prognosis, and possible adverse reactions ¹⁰. Before treatment, ask for the procedure name and write it down ¹⁰³⁰.
• Copy of medical record: Article 71 of Taiwan's Medical Care Act requires an institution to provide a copy of the record at the request of a patient it has treated, and, where necessary, a Chinese medical-record summary; it may not delay or refuse without cause, and the patient bears the required cost ⁹.
• Medical certificate: Article 17 of Taiwan's Physicians Act says that a physician may not refuse to issue a medical certificate, birth certificate, death certificate, or stillbirth certificate without a reason provided by law ¹¹. A physician prepares the medical certificate from the medical record; this site gives no advice about what it should say ¹¹³⁰. “Supporting documents” are outside National Health Insurance benefits under Article 51(10) of the National Health Insurance Act ⁴. Ask the treating institution about its application process and actual fee; medical-fee standards are approved by the municipal or county (city) competent authority ⁶¹³.

Whether those documents meet the application requirements of your policy, and whether anything else is needed, depends on the policy terms; ask the insurer that underwrote the policy. This site does not decide the effect of any document in advance ³⁰.

Risk factors: what you should know before treatment

Like every medical procedure, root-canal treatment has risks and limitations. This section concerns medical risk, not insurance. A dentist must decide whether it applies to you:

• Indications have limits: the current Cochrane review identifies the main indications as irreversible pulpitis and dental-pulp necrosis caused by caries, a coronal crack or fracture, or dental trauma ²².
• Pain can persist after treatment: a systematic review and meta-analysis included 26 studies and 5,777 teeth, with pain follow-up for 2,996 teeth. It estimated persistent all-cause tooth pain after endodontic treatment at 5.3% (95% CI 3.5%–7.2%). It also found high and statistically significant heterogeneity (I² = 80%); the frequency was 7.6% in prospective studies and 0.9% in retrospective studies ²⁴. It defined persistent tooth pain as pain still present 6 months or more after treatment ²⁴.
• A root-filled tooth is more susceptible to fracture: a review reports that root-filled teeth are generally more susceptible to fracture than vital teeth, associated with loss of tooth structure and stresses introduced by endodontic and restorative procedures ²⁵. That is why the restoration stage is not optional ²⁵²³.
• Complications can occur during treatment: the literature describes perforation as a complication that may occur during root-canal treatment and require more complex management if the tooth is to be retained ²⁶.
• Long-term results are not perfect: one systematic review pooled tooth survival after non-surgical root-canal treatment at 86% (95% CI 75%–98%) over 2–3 years, 93% (92%–94%) over 4–5 years, and 87% (82%–92%) over 8–10 years. It also states that evidence for prognostic factors is weak and ranks a crown restoration after treatment first among conditions associated with higher observed survival ²⁸. Taiwan has one nationwide claims-data study: among 517,234 teeth receiving initial root-canal treatment in 2005–2011, 29,219 were extracted and survival was 94.4% ²⁷. This retrospective National Health Insurance-claims dataset cannot cover self-paid treatment or clinical detail, and it is not a promise of any individual's result ²⁷.

All of these are group-level research findings. They cannot estimate any individual's treatment result; actual treatment and outcome vary by person and need a dentist's assessment.

Before-care checklist: 5 questions for the clinic, 3 for the insurer

Ask the clinic (the treatment side):

1. What is the name of my procedure? Is it initial root-canal treatment, root-canal retreatment, or root-end surgery? Please put it in the treatment plan ¹⁸¹⁰.
2. In this treatment plan, which items use National Health Insurance and which are self-paid? Can I receive written item-by-item information for the self-paid part? ¹⁷
3. Will the receipt state the charge items and amounts? If payment is staged, will each stage have its own receipt? ⁷
4. If I need a medical certificate, how do I apply and how long will it take? ¹¹⁴
5. If I later need a copy of my medical record or a Chinese medical-record summary, what is the procedure? ⁹

Ask the insurer (the claim side; do not ask these three questions of the dentist) ³⁰:

1. Under my policy terms, what is each of these procedure names? What documents are required, and what must the documents state?
2. Is there a time limit for submission? Are originals or copies required? What is the process for additional documents?
3. If treatment is spread over several visits and the documents are dispersed, how should they be submitted?
