Introduction
Choosing a health insurance plan should feel like buying peace of mind for your family. In practice, it often turns into a confusing exercise of staring at brochures, scanning similar-looking benefit lists, and premiums that vary for no clear reason. Most Nigerians end up comparing the wrong things, then discovering the gap when a hospital bill arrives. This explainer walks through the six mistakes most people make when comparing HMO plans, and how to compare them properly.
Most Nigerians compare HMO plans by premium and hospital list. The comparisons that actually decide whether a plan is good value are coverage limits, exclusions, hospital tiers, the HMO's NHIA accreditation, and how it handles claims.
The NHIA Act 2022 introduced a framework aimed at making health insurance universal for Nigerians and legal residents, though implementation and enforcement are still being rolled out across the country. That has pushed millions of households into the HMO market for the first time, often without a clear way to tell strong plans from weak ones.
The cost of getting it wrong is real. A single uncovered surgery can run into millions of naira. A maternity admission outside your plan's covered benefit can cost ₦400,000 or more out of pocket. Choosing badly does not just waste premium, it leaves you exposed at the moment you need cover the most.
Three structural features shape how an HMO plan behaves in practice. Most marketing material glosses over all of them.
The first is accreditation. The National Health Insurance Authority (NHIA) accredits Health Maintenance Organisations, Mutual Health Associations, and Third-Party Administrators. NHIA can also withdraw a licence where operational guidelines are breached. An unaccredited HMO is not legally permitted to sell health insurance in Nigeria, and an HMO with a recent licence query is a different proposition from one in good standing.
The second is the hospital tier system. Most HMOs band their network hospitals into tiers, typically A, B, and C, with major teaching hospitals and high-end private facilities at the top. Your plan often only covers a subset of tiers or covers higher tiers at a lower limit.
The third is how the plan pays providers. Many HMOs in Nigeria use a blended payment structure, including capitation for primary care services and fee-for-service or other reimbursement models for specialist and hospital-based treatment. The model affects how willing a hospital is to run extra tests, refer to specialists, or admit you when needed.
1. Comparing premiums first, instead of asking what the premium actually buys
The cheapest plan is rarely the best value, and the most expensive is not automatically the most comprehensive. Two plans at ₦180,000 a year can have wildly different annual limits, surgery sub-limits, and excluded benefits.
A better question is: for the premium being quoted, what is my total annual benefit limit, my surgery sub-limit, and my hospitalisation cap per night? Plans that look identical on the front page often diverge sharply once you read those numbers.
2. Trusting the hospital list at face value
A plan listing 200 hospitals sounds reassuring. It is less reassuring when you find that the two hospitals near your house are tier C with limited specialist cover, while the teaching hospital you would actually want to use is tier A and not on your plan at all.
Always cross-check the hospital list against where you live, where you work, and where you would want to be admitted in an emergency. A 50-hospital plan with the right facilities near you is more useful than a 200-hospital plan that does not include any of them.
3. Skimming the exclusions and waiting periods
Exclusions are where the real differences sit. Maternity is the most common surprise: many basic plans exclude it entirely or impose a 9 to 12 month waiting period before it kicks in. Dental and optical cover is often limited to routine check-ups, with anything more complex paid out of pocket.
Pre-existing conditions are another flashpoint. Plans treat them very differently. Some impose waiting periods, some exclude them outright, some cover them with sub-limits. Before paying any premium, read the exclusions list and the waiting period schedule in full.
4. Missing the per-benefit limits and sub-limits
A plan can have a generous overall annual limit but tight sub-limits within it. Common examples include a small cap on glasses or contact lenses, an annual ceiling on dental procedures, a per-night room rate that does not stretch to a private ward at most quality hospitals, and a surgery sub-limit that is a fraction of the headline annual benefit.
These caps are where unexpected co-payments come from. If your plan caps room charges at ₦20,000 a night and the hospital you choose charges ₦50,000, you cover the difference yourself.
5. Assuming “Comprehensive” means the same thing on every plan
“Comprehensive” is a marketing word, not a regulated definition. One HMO's “Comprehensive” plan may include international evacuation, fertility treatment, and chronic care management. Another's may simply mean inpatient and outpatient cover with standard exclusions.
Ignore the plan name. Read the benefit schedule line by line and treat the title as descriptive at best.
6. Not checking NHIA accreditation and the HMO's claims record
Accreditation is the floor, not the ceiling. An HMO can be accredited but still have a poor reputation for paying providers on time, authorising referrals quickly, or settling claims without disputes.
Hospitals talk to each other. Before signing a plan, ask two or three hospitals you would actually use whether they accept the HMO, how prompt the authorisation process is, and whether the HMO settles invoices reliably. That conversation tells you more than any brochure.
A simple seven-step framework keeps the focus on what matters.
For a salary earner enrolling a young family, the brochure trap is real. A long hospital list and a “Comprehensive” plan name at ₦450,000 a year feels reassuring, but value sits in the surgery sub-limit, paediatric specialist access, and whether your preferred hospital is on the right tier. Our HMO comparison tool surfaces those benefit-level details side by side, so the decision is made on cover, not on cover-page wording.
For a younger professional choosing her first individual plan, the comparison tilts toward maternity cover, dental and optical inclusions, and how much of the policy can be managed in-app. Two ₦220,000 plans can differ by a year-one maternity inclusion or by a 12-month waiting period. Our platform brings benefit detail and digital experience into one view, so cover and convenience can be weighed together.
Yes. The NHIA Act 2022 makes health insurance mandatory for every Nigerian and legal resident. Implementation is rolling out in stages, but the legal requirement is in force.
The NHIA maintains a register of accredited Health Maintenance Organisations, Mutual Health Associations, and Third-Party Administrators. Verify any provider on that register before purchasing a plan, regardless of how well known the brand is.
HMOs band hospitals based on cost and service level. Higher-tier hospitals usually have stronger specialist depth and higher charges. Your plan may cover lower tiers fully and higher tiers only up to a sub-limit, with you paying the balance.
A waiting period is the time between paying your premium and being able to claim a particular benefit. Maternity, dental work, and pre-existing conditions commonly carry waiting periods of three to twelve months.
Some employer-sponsored HMO plans are structured around cost-control budgets and may offer limited hospital options or lower benefit limits, though coverage quality varies significantly by employer and provider. Many salary earners hold a private top-up plan alongside the employer plan to fill the gaps.
Yes, but waiting periods usually reset on the new plan unless your new HMO offers continuity-of-cover terms. Confirm this in writing before switching, particularly if you have ongoing treatment.
Escalate to the HMO's customer service in writing, then to the NHIA. Document every interaction. The NHIA has regulatory oversight powers under the NHIA Act 2022, including the ability to investigate and take regulatory action against HMOs that breach operational requirements.
Comparing HMO plans well is mostly about asking the right questions in the right order. Start with the cover you actually need, verify NHIA accreditation, read the benefit schedule beyond the marketing page, and only then look at the premium. Done that way, the cheapest-looking plan rarely wins, and the most expensive rarely needs to.
The goal is a plan that pays when you need it, at a hospital you would actually use, for the people who matter most. Compare your options before you decide.
