Key Facts — Changing Health Insurance for 2026

The 2026 Health Insurance Switching Process

Step 1: Wait for 2026 Premium Letters (October 2025)

Don’t make any decisions until you receive your official premium letter in early October 2025. This letter contains:

• Your 2026 premium rates compared to 2025
• Any changes to your current plan
• Information about your special termination rights
• Details about deductible and model options

Important: Premium increases of 5% or more trigger special termination rights, giving you 30 days from the letter date to cancel without waiting for the November deadline.

Step 2: Research and Compare Your Options

Once you know your 2026 rates, it’s time to explore alternatives:

Step 3: Apply to Your New Insurance Provider

Critical Rule: Apply BEFORE Cancelling

Never cancel your current insurance until you have written confirmation from your new provider. Here’s the process:

1. Submit Application: Complete online application or paper forms
2. Basic Insurance: Acceptance is guaranteed - no health questions
3. Supplementary Insurance: Requires medical underwriting and separate application
4. Receive Confirmation: Get written acceptance before proceeding
5. Verify Coverage Start: Confirm 1 January 2026 start date

Application Requirements

• Personal identification (ID/passport)
• Current insurance details
• Employer information (for accident coverage coordination)
• Bank details for premium payments
• Health information (for supplementary only)

Step 4: Cancel Your Current Insurance

Only after receiving written confirmation from your new provider:

Cancellation Letter Requirements

Your registered letter must include:

• Clear intent: “I hereby cancel my basic health insurance”
• Effective date: “Effective 31 December 2025”
• Policy details: Policy number and personal information
• New coverage confirmation: Brief mention of replacement coverage
• Contact information: Current address and phone number

Sample Cancellation Letter

[Your Name and Address]
[Date]

[Insurance Company]
[Address]

Subject: Cancellation of Basic Health Insurance Policy [Policy Number]

Dear Sir/Madam,

I hereby give notice to cancel my basic health insurance policy number [XXXXX] effective 31 December 2025.

I have secured replacement coverage with [New Provider] effective 1 January 2026.

Please confirm receipt of this cancellation and provide final premium statement.

Sincerely,
[Your Signature]
[Your Name]

Send by registered mail and keep the receipt as proof of delivery.

Step 5: Coordinate the Transition

Final Checklist for Smooth Transition

• Confirm new policy start date: 1 January 2026
• Verify accident coverage: Exclude if employed ≥8 hours/week
• Update premium subsidy office: Notify if you receive cantonal support
• Transfer payment method: Set up new premium payments
• Receive new insurance cards: Should arrive by late December
• Confirm old policy ends: 31 December 2025 coverage termination

Handling Supplementary Insurance

If you’re switching supplementary coverage:

• Apply early: Medical underwriting takes 4-8 weeks
• Coordinate timing: Ensure no coverage gaps
• Document health status: Be honest about pre-existing conditions
• Consider waiting periods: Some benefits have 12-24 month waiting periods

Special Termination Rights: Your 30-Day Window

If your premium increases significantly for 2026, you have special rights:

When Special Termination Applies

• Premium increase of any amount (even 1 CHF)
• Changes to deductible options
• Modifications to insurance models offered
• Alterations to supplementary benefits

How to Use Special Termination

1. Count from letter date: 30 days from premium letter receipt
2. Send registered mail: Same process as regular cancellation
3. State special termination: Reference premium increase in letter
4. Earlier deadline: Can be earlier than 30 November if acted upon quickly

Common Mistakes to Avoid

1. Cancelling Before Securing New Coverage

Problem: Risk of coverage gap or emergency enrollment at higher cost Solution: Always apply and receive confirmation first

2. Missing the Registered Mail Requirement

Problem: Regular mail may not be accepted as valid cancellation Solution: Use registered mail service and keep receipt

3. Incomplete Cancellation Letter

Problem: Unclear intent may delay processing or be rejected Solution: Include all required information and clear effective date

4. Forgetting About Supplementary Insurance

Problem: Automatic renewal for another year if not cancelled separately Solution: Cancel supplementary with 3 months’ notice to year-end

5. Not Coordinating Accident Coverage

Problem: Double coverage or gaps in accident insurance Solution: Verify employer coverage and exclude from health insurance if applicable
