Antigua and Barbuda has a general tax-funded public hospital and clinic network (led by Mount St. John’s Medical Centre) open to legal residents, layered with a separate payroll-tax-funded Medical Benefits Scheme (MBS) that reimburses costs tied to a specific list of covered diseases and related services rather than acting as comprehensive health insurance. Here is what that actually means for an American or Briton living in Antigua and Barbuda: what the public system gives you, what it does not, and where private cover fits.
Can you use the public system?
- Working for a local employer: Only in limited cases
- Self-employed: Only in limited cases
- Retired or not working: No
Non-national applicants must show 12 consecutive months of legal residency before they can even register with MBS, and registration for non-nationals explicitly requires a work permit alongside a passport and Social Security card. Once registered, a member needs a minimum of 26 weeks (about 6 months) of contributions before benefits can be claimed. Contributions are payroll-based: employees and employers each pay 3.5 percent of wages (ages 16 to 59), reducing at 60 to 69 and dropping to zero at 70; self-employed persons pay 5 percent of earnings. No US or UK reciprocal healthcare arrangement was found.
Waiting period: 12 consecutive months of legal residency before a non-national can register, plus a minimum of 26 weeks (about 6 months) of contributions after registration before benefits become claimable.
If you are retiring here
A non-working retiree has no clear automatic route into MBS: the non-national registration category on the official MBS site lists a work permit as a required document, and the voluntary-contributor category is explicitly for people who ‘were working and have since lost their job’, not for new retirees with no prior local contribution history. Combined with the absence of any US or UK reciprocal healthcare agreement, this means a non-working retiree resident should assume no public cover route exists and treat private international health insurance as the only realistic option, though this specific conclusion is an inference from document-requirement lists rather than an explicit published MBS rule, so it is flagged as low confidence and worth confirming directly with the MBS Registration Department.
What public cover will not give you
- MBS reimburses physician visits and related costs only for a defined list of covered conditions (reported as 11 diseases), not general comprehensive primary care, so many routine and non-listed conditions fall outside it
- Each family member needs their own separate MBS membership and contribution history; there is no dependant cover riding on one person’s contributions
- Medical evacuation for complex or trauma care, commonly to the US, Puerto Rico, Trinidad or larger islands, given roughly 3.8 physicians per 10,000 population against a WHO benchmark of 10
- The decompression chamber in Antigua is not always operational, so diving-related emergencies may need evacuation
- Extensive/complex dental work (crowns, root canals, implants) is largely private-pay
- Private hospital care, generally preferred by expats for speed, modern facilities and English-language ease, sits outside MBS and is paid privately or via private insurance
So do you need private health insurance?
Private international health insurance is genuinely necessary in practice for most expats, given MBS’s 12-month/26-week entry barrier and its narrow, disease-specific scope. It is also an explicit, stated legal requirement for two specific routes: the Citizenship by Investment Programme (a health insurance certificate is a required application document) and the Nomad Digital Residence visa (mandatory health insurance covering the stay). Whether it is formally mandated for the standard, non-CBI Permanent Residence Certificate route (as opposed to just a medical exam/health certificate) could not be confirmed from official sources. Proof of health insurance is also a condition of the main residence routes here, so most expats need a policy in place before they apply.
