Non-Covered Services in Orthodontics: What Statutory Insurance Patients Pay Extra

You’re holding the treatment and cost plan in your hands — and you stumble over terms like “additional cost agreement,” “non-contracted services,” or “patient contribution.” What does health insurance actually cover? What can be reduced? And what is medically useful versus pure comfort? This article provides clarity — without legal jargon, without marketing promises.

What are elective services in orthodontics?

Non-contracted services — also referred to as additional services, supplemental services, or simply private services — are all treatment components that go beyond the statutory standard care. They are paid for by the patient or parents themselves and are documented in a written additional cost agreement.

The legal basis is Section 29 of the German Social Code, Book V (SGB V)2; the elective additional services are defined in the catalog of Annex B to the Federal Framework Agreement for Dentists (BMV-Z). Before treatment begins, an additional cost agreement is signed in writing, specifying which services will be billed privately and at what cost. If the treatment and cost plan does not show a clearly separated private portion, you should ask — and if in doubt, seek a second opinion.

Important context: Non-contracted services are not inherently unnecessary or overpriced. Many of these items are medically beneficial, esthetically superior, or gentler than the insurance-covered version — they are simply not included in the benefit catalog of statutory health insurance.

How does insurance coverage work in orthodontics?

Before we discuss additional services, it’s worth looking at what statutory health insurance (GKV) standard care actually covers. Three aspects are decisive: the KIG classification, the fixed subsidy, and the special regulation for adults.

KIG classification: only levels 3 to 5 are covered by insurance

The orthodontic indication group (Kieferorthopädische Indikationsgruppe, KIG) classifies dental and jaw misalignments into five severity levels — from KIG 1 (minor) to KIG 5 (extremely severe). Statutory health insurance covers treatment only for KIG 3, 4, or 5: The orthodontic guidelines of the Federal Joint Committee (Gemeinsamer Bundesausschuss) require “a classification of at least treatment need grade 3 of the indication groups.”1 KIG 1 and 2 are considered cosmetic corrections from the insurer’s perspective — parents bear the full cost themselves.

The classification is made by the orthodontist using standardized diagnostic criteria. It is binding and cannot be “negotiated.”

Fixed subsidy principle: advance payment, then reimbursement

For a recognized indication (KIG 3–5), statutory health insurance covers the fixed subsidy in two steps: 80 percent of the costs are covered directly throughout treatment. Parents initially pay the remaining 20 percent. § 29 SGB V provides for reimbursement “once treatment has been completed to the medically necessary extent determined by the treatment plan.”2 If treatment is discontinued early, reimbursement is forfeited.

Important: The fixed subsidy applies exclusively to standard care with fixed metal braces. Everything beyond that — and this is the core point of this article — must be paid for privately.

Adults: Generally Self-Pay

Adults 18 years and older are generally self-payers in orthodontics — the relevant criterion is age at treatment start. Statutory health insurance covers treatment only in exceptional cases: for severe jaw anomalies requiring combined orthognathic surgery. The guideline lists treatment need grades A5, D4, M4, O5, B4, or K4 for this purpose.1

For all other adults — such as the working patient seeking discreet tooth correction with Invisalign treatment — the complete treatment costs are out-of-contract. This applies even when there is a clear medical need for treatment.

The Seven Most Common Out-of-Contract Services at a Glance

Which additional services are offered to you depends on the diagnosis, individual circumstances, and the practice. The following items appear most frequently in treatment and cost plans:

1. Aligner Therapy (e.g., Invisalign)

Clear, removable plastic aligners instead of fixed brackets. For children and adolescents with KIG 3–5, standard care with fixed braces remains the statutory benefit; if you choose aligners instead, the treatment is a private service — statutory insurance does not contribute. For adults, entirely private in any case. You can find a detailed breakdown in our article on Invisalign costs.

2. Ceramic or Sapphire Brackets

Esthetic alternatives to metal brackets in fixed treatment. They are less visible but somewhat more fragile and more expensive in material. Statutory coverage corresponds to metal brackets — you pay the surcharge privately.

3. Self-Ligating Brackets

Metal brackets that hold the archwire with a clip mechanism instead of an elastic band. They provide better oral hygiene access and shorter chair time. Statutory coverage corresponds to metal brackets — you pay the surcharge privately.

4. Bracket Sealing Against Demineralization

A thin protective layer around the brackets that helps prevent cavities and white spots (so-called white spot lesions) during treatment. Medically advisable for patients with moderate to high caries risk — but considered a comfort service from the insurance perspective.

5. 3D Diagnostics and Intraoral Scan

Instead of traditional impression material, the jaw is digitally captured with an intraoral scanner. More precise, more comfortable, faster — and the basis for digital treatment planning and aligner fabrication. Statutory insurance sometimes reimburses only the traditional impression.

6. Mini-Pins (Mini-Implants, TAD)

Small, temporarily placed screws in the jawbone that serve as anchorage for especially precise tooth movements. Temporary Anchorage Devices, or TAD, make treatments possible that previously would have required surgical intervention. Medically indicated in complex cases.

7. Premium Retainer

After active treatment comes retention — stabilizing the treatment result. Retainers are not covered by statutory health insurance — this applies to simple removable retainers as well as fixed lingual retainers, individually milled splints, or multi-layer retainer sets. Supplemental dental insurance reimburses the costs depending on the plan.

The supplementary cost agreement: what you’re signing — and what you need to watch for

The supplementary cost agreement is not a burdensome form, but your legal protection. It lists each non-covered service individually, with description and price. It must be provided in writing before treatment begins — verbal assurance is not sufficient.

Before signing, check three points:

• Clear separation: Statutory and private portions must be shown separately in the treatment plan. Lump sums without itemization are a warning sign.
• Individual items instead of packages: Each additional service should appear with its own description and price. This way you can decline individual items.
• Disclosure of alternatives: The practice must explain what statutory version would be available for each private service — and what the difference is.

Be cautious if additional services are added only during ongoing treatment or if “premium packages” are offered without individual prices. A reputable practice provides disclosure upfront — and allows time for your decision.

Who pays what? Three typical examples from daily practice

To make the abstract logic tangible, here are three anonymized examples — all from our practice’s experience:

Example 1: Child with KIG 3, conventional treatment

Mia, 12 years old, significantly protruding front teeth, KIG 3 assessment. The parents choose fixed metal braces as standard care. Insurance portion: 80% during treatment, 20% reimbursed upon completion. Non-covered: only bracket sealing as protection against white spots — a deliberate decision by the parents, not a mandatory item.

Example 2: Teenager requesting aligners

Lina, 15 years old, KIG 4, strongly prefers Invisalign over metal brackets — she wears the braces throughout the school day. Insurance portion: Statutory health insurance pays nothing for aligner treatment. Non-covered: Treatment is billed entirely as private service.

Example 3: Adult with Invisalign treatment

Anna, 32 years old, mild crowding of lower front teeth, frequent client contact professionally. No entitlement to statutory benefits. Insurance portion: none. Non-covered: complete aligner therapy including intraoral scan, digital treatment planning, and fixed lingual retainer for stabilization.

Private dental supplementary insurance: is it worthwhile?

Private dental supplementary insurance can cushion part of the non-covered costs — but only under two conditions: It was purchased before an orthodontic treatment need was identified. And it explicitly covers orthodontic services.

Insurance providers assess health status before coverage begins. A previously documented KIG finding almost always results in the exclusion of orthodontic benefits. For parents, this means: Anyone planning supplemental insurance for their child should enroll as early as possible — ideally during preschool years, before any findings are documented.

The same applies to adults: Supplemental insurance after treatment needs have been identified usually provides no benefit. The situation differs with long-term planning — for instance, if a future correction is being considered.

Frequently asked questions about elective services

What are elective services in orthodontics?

Out-of-contract services are all treatment components that go beyond statutory basic care. These include esthetically superior materials such as clear aligners or ceramic brackets, as well as extended diagnostics such as intraoral scanning and comfort services such as bracket sealing. They are documented in a written additional cost agreement.

Which orthodontic services does statutory health insurance cover?

Statutory health insurance covers standard care for children and adolescents under 18 years of age, provided an orthodontic indication group 3, 4, or 5 (KIG 3–5) is present. For adults, only severe jaw anomalies requiring combined orthognathic surgery are covered.

What is the out-of-pocket portion for braces?

For treatment covered entirely by statutory health insurance, the insurer covers 80 percent of treatment costs directly; parents initially pay the remaining 20 percent.2 This is reimbursed by the insurer after successful completion of treatment. In addition come the privately chosen non-contractual services — their extent determines the actual out-of-pocket cost.

What is an agreement for additional costs?

The additional cost agreement is a written contract between patient and orthodontist that itemizes all out-of-pocket services with individual prices. It must be signed before treatment begins and is mandatory as soon as additional services are provided.

Is Invisalign covered by statutory health insurance?

No. Aligner therapies such as Invisalign are generally out-of-pocket services and are not covered by statutory health insurance.

Is private dental insurance worthwhile for orthodontic treatment?

Private dental insurance can be worthwhile if taken out before an orthodontic treatment need has been identified. Insurers review the health status and typically exclude pre-existing conditions. It therefore makes sense to take out coverage as early as possible during childhood.

Which out-of-pocket services are medically sensible?

Which additional services are medically sensible depends on the individual diagnosis and personal priorities. Commonly recommended options include bracket sealing as protection against demineralization, intraoral scanning for precise diagnostics without impression material, and esthetic brackets when esthetic concerns are pronounced.

How do I recognize trustworthy cost disclosure in orthodontics?

A trustworthy practice clearly separates statutory and out-of-pocket portions in the treatment plan, provides the additional cost agreement in writing before treatment begins, and explains each item individually. Surprise charges during treatment or bundled premium packages without itemization are warning signs.
