How Does Health Insurance Work in Nigeria? What Every Nigerian Needs to Know Before Falling Ill

Imagine waking up with a medical emergency, rushing to the hospital, and finding out the treatment you need costs more than three months of your salary. For millions of Nigerians, this is an everyday reality. But it doesn’t have to be. Health insurance is changing the game, offering a system where you don’t always have to pay out of pocket when life takes a turn. If you’ve ever asked, “How does health insurance work in Nigeria?”—this article will give you the real picture.

The Concept Behind Health Insurance in Nigeria

At its core, health insurance is a plan that allows you to receive medical care without paying full costs each time you visit the hospital. Instead of footing the bill directly, you contribute a set amount regularly—monthly, quarterly, or yearly—to an insurance company or an HMO. This contribution is called a premium.

Once your premium is paid and your plan is active, you’re entitled to receive medical services covered under that plan. When you visit a hospital that works with your provider, your insurer pays for the services you receive, depending on what your plan covers. In short, it’s a shared risk model. Everyone in the system pays into a pool, and those who fall sick draw from it when needed.

Who Regulates Health Insurance in Nigeria?

In Nigeria, health insurance is overseen by the National Health Insurance Authority (NHIA), which replaced the older NHIS framework. The NHIA is responsible for ensuring that registered HMOs and healthcare providers offer proper coverage and don’t exploit enrollees. It also handles public health insurance plans for federal workers, students, retirees, and low-income groups.

Private HMOs are regulated by NHIA as well. They offer health plans for individuals, families, SMEs, large corporations, and specific communities. Each HMO has a network of partner hospitals that provide treatment for clients under their cover.

Types of Health Insurance Plans Available

In Nigeria, you’ll typically find two main types of health insurance: public and private.

The public option is mostly reserved for civil servants and low-income earners under government-subsidized plans. This includes programs like the Formal Sector Social Health Insurance Program (FSSHIP), the Tertiary Institutions Social Health Insurance Program (TISHIP), and the Vulnerable Group Health Insurance Scheme.

Private health insurance, on the other hand, is open to everyone. It includes plans for individuals, families, and companies. You get to choose your provider, plan tier, and preferred hospital.

These plans vary in price and coverage. Lower-tier plans cover basic outpatient services, common medications, and maternal care. Higher-tier options may cover surgeries, advanced diagnostics, dental and optical services, and even emergency evacuations.

What Happens After You Subscribe?

Once you subscribe and make payment, your provider gives you an insurance card or digital ID. This card contains your unique ID number and provider details. When you need medical attention, you simply present your card at any of the accredited hospitals listed by your HMO.

Before you start using the plan, there’s usually a waiting period. This could range from 2 to 4 weeks after payment. During this period, your full coverage is not yet active. However, some providers may allow emergency treatment within this timeframe.

Your Primary Provider and How to Access Care

When signing up for a plan, you’re required to choose a primary healthcare provider (PHP)—this is usually a hospital or clinic closest to you. All your treatments must be routed through this provider, unless your plan includes flexible access.

If your primary provider cannot handle your case, they will refer you to a secondary or tertiary facility. This is especially common for surgeries or specialist treatment. The referral must be approved by your HMO for your treatment to be covered.

For example, if you have a plan that includes surgery but your PHP lacks a surgeon, you’ll be referred to another hospital. Your HMO must authorize the referral before you receive treatment.

How HMOs Make Payments to Hospitals

Every time you access treatment, the hospital sends a report and billing to your HMO. The HMO verifies that the treatment is within your plan’s scope, and if it is, they process payment directly to the hospital. You’re not required to pay anything out of pocket unless the service you received is excluded from your plan.

Some treatments may require pre-authorization, especially for surgeries, long-term hospital stays, or advanced diagnostics. If you go ahead with such treatment without approval, you might have to cover the cost yourself.

Common Services Covered Under Most Health Insurance Plans

While plans differ, most health insurance packages in Nigeria cover the following:

• Outpatient consultation and treatment
• Basic laboratory investigations
• Hospital admissions and basic surgeries
• Maternity care and delivery
• Treatment for common illnesses like malaria, typhoid, and infections
• Chronic condition management (like hypertension and diabetes)
• Access to general practitioners and some specialists

More advanced or premium plans may also include:

• Dental care
• Eye care (glasses, testing, surgery)
• Radiology and advanced scans (CT, MRI)
• Emergency care
• Ambulance services
• Cancer treatments and dialysis

You should always confirm what’s covered and what’s excluded before subscribing.

What’s Not Covered Under Most Plans

No matter how fancy your plan sounds, every policy comes with exclusions. These are services your HMO won’t pay for, even if you need them. Common exclusions include:

• Cosmetic surgery
• Infertility treatments
• Non-prescribed drugs
• Experimental procedures
• Self-inflicted injuries
• Treatments done at non-accredited hospitals

Always read the policy terms before signing up. If there’s something you know you’ll likely need in the future—like dental braces or fertility support—look for plans that offer those as optional add-ons.

Switching Providers or Hospitals

You can switch hospitals or HMOs, but there are rules. Most HMOs only allow you to change your primary hospital once every three or six months. If your chosen hospital is underperforming or too far, request a change by contacting your HMO’s support. Changing your HMO is possible, especially if you’re under a private plan. However, your existing plan must be completed or canceled before switching. Also, you may need to serve a new waiting period under your new provider.

Emergency Care and Walk-In Treatments

Some health insurance plans include emergency coverage, allowing you to access treatment anywhere in Nigeria. But others limit you to your chosen hospital. This can be frustrating in urgent cases. If emergency care is important to you, choose a provider with a wide hospital network and emergency access. Certain premium plans also allow you to walk into any partner hospital without a referral. These plans are more expensive but offer greater flexibility and convenience.

Handling Complaints and Disputes

If your hospital refuses to treat you or your HMO delays payment, you can report them to the NHIA. The authority investigates such complaints and can penalize non-performing providers. Before it gets to that, you should try resolving the issue directly. Contact your HMO’s account officer or customer care team. If the matter isn’t resolved, escalate it to the NHIA with evidence of the complaint.
