Health Insurance After Divorce in Australia

Splitting health insurance after divorce isn't just about updating contact details — it affects your tax obligations, your children's coverage, and your privacy. A shared Medicare card lets your ex-spouse view your medical claims and Safety Net records. And dropping from a family private health insurance policy to no cover at all can trigger the Medicare Levy Surcharge.

Separating Your Medicare Card

If you and your ex-spouse share a Medicare card, either of you can view the other's medical claims and Safety Net history. Separating the card is straightforward but must be done deliberately.

How to split the card:

1. Call Medicare (Services Australia) or visit a Service NSW / Services Australia centre
2. Request a new individual Medicare card in your name only
3. If you have children, decide whose card they'll be listed on (they can appear on both parents' cards)
4. Your new card number will be different — update it with every healthcare provider, pharmacy, and specialist

Privacy sequence matters: unlink your shared Services Australia records before updating your new address or bank details. If you update first, your ex-partner can potentially see your new address and banking information through their own MyGov portal. Separate the records, then update the details.

The digital Medicare card in your myGov app wallet updates automatically once the phone or in-person update is processed.

Private Health Insurance: What Changes

If you held a joint or family private health insurance policy, you'll need to restructure coverage. The options:

If you were the policy holder:

• Contact your insurer to remove your ex-spouse from the policy
• Downgrade from a couples/family policy to singles or single-parent if applicable
• Your premium will decrease, but check that your coverage levels are still appropriate

If your ex-spouse was the policy holder:

• You lose coverage the moment you're removed from their policy
• Take out a new individual or single-parent policy to avoid coverage gaps
• Ask your new insurer about transfer certificates — these preserve your waiting periods so you don't have to re-serve them for hospital treatment

Children's cover: children can be covered under either parent's policy. If both parents maintain private cover, you can choose which policy covers the children — or split them if your insurer allows. Coordinate this to avoid both parents paying for duplicate children's cover.

The Medicare Levy Surcharge Trap

If your individual income exceeds $93,000 (2025-26 threshold for singles), you'll pay the Medicare Levy Surcharge of 1-1.5% on top of your regular Medicare levy — unless you hold an appropriate level of private hospital cover.

When you were married or in a de facto relationship, the threshold was based on combined family income ($186,000 for couples). After separation, the threshold drops to the singles level. This means some people who were comfortably below the surcharge threshold as a couple suddenly exceed it as an individual.

Check your income against the current thresholds and take out at least basic hospital cover if you're above them. The surcharge often costs more than a basic hospital policy.

Lifetime Health Cover Loading

If you're over 31 and have never held private hospital cover (or had gaps longer than 1,095 continuous days), you'll face a Lifetime Health Cover (LHC) loading — an extra 2% added to your premium for each year you're over 30 when you first take out hospital cover, up to a maximum 70% loading.

This matters after divorce if your ex-spouse was the policy holder and you've never held cover in your own name. Getting your own policy quickly avoids the loading clock continuing to tick.

Steps to Sort Health Insurance After Divorce

1. Separate the Medicare card — call Services Australia before updating your address
2. Review the private health insurance situation — who holds the policy, who stays, who needs new cover
3. Check the MLS threshold — is your individual income above $93,000?
4. Get a transfer certificate if taking out a new policy — preserves waiting periods
5. Update all healthcare providers with your new Medicare card number and private health fund details

The NSW After-Divorce Checklist includes templates for notifying your health fund and a checklist for separating Medicare records — tasks that feel small but protect your medical privacy and can save thousands in unexpected tax surcharges.
