Nigeria’s Health Insurance Gap Deepens as Medical Bills Push More Households Towards Financial Hardship
ABUJA, Nigeria — Access to healthcare in Nigeria is becoming an increasingly difficult financial calculation for millions of households, as families confront medical expenses in a system where out-of-pocket payments remain the dominant source of healthcare financing.
For low-income earners, the consequences can be particularly severe. A routine consultation, diagnostic test, prescription or hospital admission can quickly consume a significant portion of household income, while serious illness can create expenses that exceed what many families can reasonably afford.
The challenge is not simply the price of individual medical services. It is also the structure of healthcare financing in Nigeria, where health insurance coverage remains limited and households continue to carry a large share of the cost of treatment directly.
The African Health Observatory Platform, drawing on Nigeria’s health-system data, reports that out-of-pocket spending accounts for more than 75 per cent of total health expenditure in the country — among the highest levels globally. It also notes that Nigeria’s health spending remains below international benchmarks. (Aho)
The Commonwealth Fund’s latest Nigeria profile similarly estimates that out-of-pocket payments represented about 76 per cent of total health spending and that approximately 91 per cent of Nigerians were uninsured as of 2024. (Commonwealth Fund)
These figures underline the scale of the financial protection challenge confronting the country’s healthcare system.
When illness becomes a household economic crisis
For families without adequate insurance, healthcare is often financed from money that would otherwise be used for food, rent, education, transportation or other basic necessities.
This makes illness not only a health concern but also an economic risk.
A household may be able to manage the cost of an ordinary doctor’s appointment or a short course of medication. The financial equation changes dramatically when treatment involves surgery, prolonged hospitalisation, specialised investigations, cancer care, dialysis, maternity complications or other expensive interventions.
In such circumstances, families may be forced to borrow money, sell assets, seek assistance from relatives or delay treatment.
The problem is particularly serious for households whose incomes have been squeezed by the broader cost-of-living pressures of recent years.
Nigeria has undergone major economic reforms since 2023, including the removal of the petrol subsidy and changes to the foreign-exchange system. Although the government and international financial institutions have pointed to improvements in some macroeconomic indicators, the reforms have also generated significant adjustment costs for households.
Reuters reported in July 2026 that Nigeria’s Finance Minister said savings from subsidy removal and foreign-exchange reforms had largely been absorbed by higher debt-servicing costs and increased government spending, while Nigerians continued to face the consequences of higher living costs.

For families already operating on narrow margins, healthcare expenses therefore compete directly with other essential household needs.
Insurance remains the missing financial shield
Health insurance is intended to spread the financial risk of illness across a larger pool of contributors, reducing the amount an individual must pay when medical treatment becomes necessary.
Nigeria’s National Health Insurance Authority was established under the National Health Insurance Authority Act of 2022, replacing the former National Health Insurance Scheme framework.
The authority’s stated objective is to achieve universal health coverage and provide financial access to quality healthcare for Nigerians.
The NHIA says its programmes cover formal-sector workers, organised private-sector employees, vulnerable groups, self-employed Nigerians and other categories of the population. Its framework also includes State Social Health Insurance Schemes and programmes aimed at vulnerable populations. (National Health Insurance Authority)
But the existence of a national insurance framework does not automatically translate into universal effective coverage.
The central challenge is reaching people outside the formal economy.
Millions of Nigerians work in informal employment, including petty trading, agriculture, transportation, domestic services, construction and other occupations where regular payroll deductions and employer-sponsored insurance are unavailable.
For these workers, enrolling in health insurance may require individual payments and sustained awareness of the benefits.
The result is a large gap between the policy objective of universal health coverage and the financial reality experienced by many households.
NHIA’s expansion agenda
The NHIA has continued to position insurance expansion as a major part of Nigeria’s strategy for reducing financial barriers to healthcare.
Its current programmes include coverage mechanisms for formal workers, the private sector, vulnerable groups, the self-employed and state-based social health insurance schemes.
The authority says state schemes are expected to establish equity funds aimed particularly at poor and vulnerable residents. According to the NHIA, such schemes can cover some or all of the costs associated with consultations, hospital stays and emergencies, depending on the programme. (National Health Insurance Authority)
The authority also promotes coverage for informal-sector workers and self-employed Nigerians, an important area because insurance expansion cannot achieve national scale if it remains concentrated among salaried workers.
The challenge, however, is not only enrolment.
Insurance must also provide meaningful financial protection when people actually need healthcare.
A card that does not adequately cover medicines, diagnostic procedures, specialist treatment or other necessary services may leave patients exposed to significant additional payments.
The quality, availability and affordability of healthcare providers participating in insurance schemes are therefore as important as the number of people formally registered.
Out-of-pocket payments remain a major obstacle
The World Health Organization identifies financial protection as one of the central pillars of universal health coverage.
Its 2025 Global Monitoring Report states that 2.1 billion people globally experienced financial hardship due to out-of-pocket health spending in 2022, demonstrating that healthcare costs remain a significant international development challenge. (World Health Organization)
For Nigeria, the problem is particularly pronounced because of the country’s exceptionally high dependence on direct household payments.
The African Health Observatory’s Nigeria health-system profile says out-of-pocket expenditure accounts for more than three-quarters of total health expenditure. (Aho)
This creates what health economists describe as financial vulnerability: the possibility that a medical event can destabilise a household’s finances.
The poorest households are often the most exposed because they have fewer savings and fewer assets to fall back on.
Consequently, financial protection is not simply a question of making hospitals more affordable. It is also about preventing medical emergencies from becoming pathways into deeper poverty.
The informal economy presents a difficult test
Nigeria’s large informal economy presents one of the biggest tests for universal health insurance.
Formal-sector employees can generally be reached through payroll and employer structures. Informal workers require a different approach.
A market trader, farmer or motorcycle operator may have irregular income and may be reluctant to commit scarce resources to an insurance contribution when there is no immediate medical need.
This creates a familiar challenge in insurance systems: people may prioritise immediate household expenses over protection against an uncertain future risk.
The policy response therefore requires more than simply making insurance mandatory or available.
It requires affordable contribution structures, convenient registration, public education and confidence that enrolled patients will actually receive quality services when they present at health facilities.
The NHIA has recognised the need to extend coverage beyond conventional employment structures, with programmes specifically targeting self-employed people and vulnerable populations. (National Health Insurance Authority)
Rising costs can weaken the value of insurance
Another challenge is the relationship between insurance premiums and the actual cost of healthcare.
When the cost of medicines, equipment, diagnostics, personnel and hospital operations increases, insurers and healthcare providers face pressure to adjust their rates and reimbursement arrangements.
If premiums rise too quickly, households may struggle to maintain coverage.
If premiums remain artificially low without corresponding funding, healthcare providers may face delayed payments or inadequate reimbursement, potentially affecting the quality and availability of services.
This creates a difficult policy balance.
Nigeria needs insurance products that households can afford, but those products must also be sufficiently funded to support sustainable healthcare delivery.
The solution cannot simply be to shift the financial burden from patients to insurers without addressing the underlying cost and capacity problems within the healthcare system.
Public investment remains critical
Health insurance cannot operate effectively in isolation from the broader healthcare system.
Insurance can help patients pay for services, but it cannot by itself create functioning hospitals, recruit sufficient healthcare workers, guarantee medicine availability or provide reliable electricity and equipment.
Nigeria’s health-system financing remains comparatively low.
The African Health Observatory reports that current health expenditure was about 4 per cent of GDP in 2021 and notes that the national health budget has remained below the 15 per cent benchmark associated with the Abuja Declaration. (Aho)
This means Nigeria’s universal health coverage ambition requires simultaneous progress in financing, insurance, primary healthcare, infrastructure, workforce development and accountability.
The quality of public health facilities is especially important for low-income Nigerians.
Where public facilities are unable to provide timely and reliable care, patients may be pushed toward private hospitals, where costs can be considerably higher.
That can further deepen the financial divide between households that can afford private treatment and those that cannot.
The cost of delaying treatment
High out-of-pocket healthcare costs can influence not only how people pay for treatment but whether they seek treatment at all.
When a family knows that a hospital visit could generate an unaffordable bill, it may postpone consultation, self-medicate or rely on informal alternatives.
Delaying treatment can allow relatively manageable conditions to become more serious and expensive.
This creates a cycle in which financial barriers contribute to poorer health outcomes, while worsening health creates larger financial demands.
Breaking that cycle requires stronger primary healthcare and affordable early intervention.
Universal health coverage therefore should not be measured solely by how many people possess insurance cards.
The more important question is whether Nigerians can obtain appropriate healthcare when they need it without being pushed into financial distress.
A policy challenge that requires trust
For Nigeria’s health insurance reforms to succeed, public confidence will be crucial.
People are more likely to contribute to an insurance programme when they believe that the system will work when they need it.
That requires transparent administration, timely payment to healthcare providers, effective regulation of HMOs and insurance agencies, clear benefit packages and mechanisms for resolving complaints.
The NHIA says beneficiaries under its programmes can access defined healthcare benefits and that its broader mandate includes financial protection, fairness and quality improvement. (National Health Insurance Authority)
Turning those objectives into widespread public experience will be the real test.
Nigeria’s healthcare financing challenge cannot be solved by government alone. Employers, insurers, state governments, healthcare providers, civil-society organisations and citizens all have roles to play.
But government remains responsible for establishing the regulatory and financial environment in which the system can function effectively.
The road to universal health coverage
Nigeria’s ambition of achieving universal health coverage by 2030 remains possible, but the scale of the financing challenge is considerable.
The country has already established a legal and institutional framework for expanding insurance coverage. The NHIA Act provides the basis for a broader national system, while state insurance agencies provide additional channels for reaching local populations. (National Health Insurance Authority)
The next stage must be implementation at scale.
That means making insurance affordable for informal workers, strengthening vulnerable-group financing, improving the quality of primary healthcare and ensuring that insurance coverage translates into real access to treatment.
It also means addressing the underlying affordability of medicines, diagnostics and hospital services.
For millions of Nigerians, health insurance is not merely a financial product.
It can determine whether a family sells an asset to pay a hospital bill, borrows money to obtain treatment, delays care or receives medical attention when it is most effective.
As household finances remain under pressure, the stakes are becoming higher.
The central measure of Nigeria’s health-insurance reform should therefore be straightforward: whether ordinary Nigerians can obtain necessary healthcare without having to choose between medical treatment and other basic necessities.
Until that protection becomes widespread, the country’s healthcare financing gap will remain one of its most pressing social and economic challenges.
