I can provide you with some general information about health insurance in Dubai. Keep in mind that the status and availability of health insurance companies may change, and it's always recommended to check the latest information.

In Dubai, health insurance is mandatory for all residents, including expatriates and their dependents. The Dubai Health Authority (DHA) has a list of approved health insurance providers. Residents must choose a health insurance plan from these approved providers to meet the visa and residency requirements.

Some of the health insurance companies operating in Dubai as of my last update include:

1. AXA Insurance
2. Daman - National Health Insurance Company
3. Oman Insurance Company
4. MetLife Alico
5. Dubai Insurance Company
6. Abu Dhabi National Insurance Company (ADNIC)
7. Allianz Partners
8. Salama Islamic Arab Insurance Company

Please note that this is not an exhaustive list, and there are several other insurance companies authorized by the DHA. It's essential to check the latest list provided by the Dubai Health Authority or consult with your employer's HR department for updated information on approved health insurance providers.

Additionally, new companies may enter the market, and existing ones may undergo changes, so it's advisable to verify the information from official sources or directly with the relevant authorities for the most up-to-date details.
