Employer medical cover and VHIS: choosing a deductible

Check what employer medical insurance actually pays before choosing a personal VHIS deductible. A headline group limit is not the amount paid on every bill, nor an automatic offset against a personal deductible. This guide helps structure the comparison; it does not recommend a particular deductible.

Three questions before supplementing employer cover

1. How much would the employer policy actually reimburse for this bill?
2. Do the individual policy terms allow already-paid eligible expenses to reduce its deductible?
3. Could you afford the remaining costs with no group payment after leaving work or retiring?

The same hypothetical bill below illustrates the decision. At the end, switch group-payment scenarios to see how out-of-pocket costs change.

Obtain both policies first

Question to confirm	Why it matters
What are hospital, surgery and diagnostic limits?	Annual cover does not determine each reimbursable item
Which items have coinsurance or exclusions?	Some costs may remain payable by you
How do payments by another policy count towards the deductible?	Actual terms govern coordination; do not simply add cover limits
Which insurer receives the claim first, and which documents are needed?	Confirm settlement statements and receipt requirements
What happens on leaving, retiring or changing jobs?	Do not assume group cover continues
Can the personal deductible be reduced later?	Check timing, underwriting and conditions

Official VHIS FAQ Q3 distinguishes individual certified plans from employer-purchased group insurance. They are not governed by identical product rules. Official explanation

One HK$80,000 bill, three employer-payment scenarios

These are hypothetical teaching examples, not results for named plans.

Assume the entire HK$80,000 is eligible under both policies, the unused personal annual deductible is HK$25,000, and there are no other limits or coinsurance. Assume the terms allow eligible expenses already reimbursed by the group policy to reduce the remaining personal deductible, without duplicate reimbursement of the same costs.

Actual group payment	Unpaid bill	Remaining deductible after offset	Illustrative personal payment	You pay
HK$20,000	HK$60,000	HK$5,000	HK$55,000	HK$5,000
HK$35,000	HK$45,000	HK$0	HK$45,000	HK$0
HK$0	HK$80,000	HK$25,000	HK$55,000	HK$25,000

In the first row: HK$80,000 − HK$20,000 − HK$55,000 = HK$5,000. Each row's group payment, personal payment and patient share add up to HK$80,000. If eligible items differ between policies, recalculate item by item instead of applying this example.

A clause example appears in official registry document F00059-04-000-01, which describes other-insurance payments reducing a deductible. This is a specific document, not a universal rule. Check its version and your own terms.

Repeat the exercise without employer cover

The third row is a budgeting exercise without a group payment. Add possible exclusions and above-limit expenses to assess affordability. Consider retirement, job changes and changes to group benefits rather than relying solely on today's group limit.

Record annual premium savings separately from possible extra out-of-pocket costs. The former concerns a fixed period; the latter depends on claims and terms. Dividing one by the other does not establish which option will certainly be better.

Use the tools together

• Compare Plans: compare standard premiums for different deductibles using consistent inputs.
• Reimbursement examples: distinguish item limits from deductibles.
• Claim estimator: compare personal plans on one case. It does not approve coordinated claims across two policies.
• Premium and renewal guide: understand price and renewal comparisons.

Frequently asked questions

Q1: If employer cover exceeds the deductible, will I pay nothing?

Not necessarily. Actual payments, eligible expenses, coordination terms and other restrictions matter.

Q2: Can I automatically reduce my deductible to zero after leaving a job?

Do not assume so. Confirm the personal policy's conversion and underwriting conditions.

Q3: Which policy should receive the claim first?

Confirm the order and documents with both insurers and disclose other reimbursements. This guide does not prescribe one order for every policy.
