NHIS in Nigeria: What It Covers and What You'll Still Pay Out of Pocket (2026 Guide)

If you're enrolled in the National Health Insurance Scheme (NHIS), now operating under the National Health Insurance Authority (NHIA), you've probably asked: "What exactly does my coverage include, and when will I still need to pay from my own pocket?"

The short answer: NHIS covers a wide range of essential health services—from outpatient consultations and maternity care to basic dental and eye care—but there are important exclusions and co-payments you need to know. Understanding these details helps you budget for healthcare, avoid surprise bills, and make informed decisions about supplemental coverage.

In this guide, I'll walk you through the NHIS benefit package, break down what's fully covered, what requires co-payment, and what's excluded entirely. I'll also show you real examples of out-of-pocket costs and tie in ToolBase's NHIS Contribution Calculator to help you plan your monthly deductions. Let's dive in.

What Is NHIS and How Does It Work?

The National Health Insurance Scheme (NHIS) was established by Decree 35 in 1999 and became operational on June 6, 2005. In May 2022, the National Health Insurance Authority (NHIA) Act was signed into law, transforming NHIS into the National Health Insurance Authority (NHIA) and making health insurance mandatory for all Nigerians and legal residents.

Under the NHIA Act, employers with five or more staff must enroll employees in NHIA-approved health insurance plans, covering the employee, one spouse, and up to four children under 18. The scheme operates through Health Maintenance Organizations (HMOs), which act as intermediaries between enrollees and accredited healthcare providers.

Contribution Rates for Formal Sector Workers

If you're in the formal sector (public or private), your NHIS contribution is based on your basic salary:

• Employer contribution: 10% of your basic monthly salary
• Employee contribution: 5% of your basic monthly salary
• Total: 15% of basic salary remitted to the NHIA Fund Account

For consolidated salary structures, the split is 3.25% from the employer and 1.75% from the employee monthly.

Example: If your basic salary is ₦200,000:

• Employer pays: ₦20,000 (10%)
• You pay: ₦10,000 (5%)
• Total monthly contribution: ₦30,000

You can use ToolBase's NHIS Contribution Calculator to estimate your monthly deductions based on your salary structure.

The NHIS Benefit Package: What's Fully Covered

The NHIS benefit package is comprehensive by design and includes the following services at no additional cost (except for the 10% drug co-payment discussed later):

1. Outpatient Care

What You'll Still Pay Out of Pocket

Even with NHIS coverage, there are several scenarios where you'll need to pay from your own pocket. Here's what to expect:

1. 10% Drug Co-Payment

This is the most common out-of-pocket expense for NHIS enrollees. For every prescription, you pay 10% of the total cost of drugs as listed on the NHIS drug price list.

Example: If your prescription costs ₦5,000:

• NHIS covers: ₦4,500 (90%)
• You pay: ₦500 (10%)

Over a year, this can add up—especially if you're managing chronic conditions like hypertension or diabetes that require monthly medications.

2. High-Technology Investigations (50% Co-Payment)

CT scans, MRIs, and other advanced imaging are partially excluded. The HMO pays 50% of the cost, and you cover the remaining 50%—unless it's a life-threatening emergency.

Example: If an MRI costs ₦80,000:

• HMO pays: ₦40,000
• You pay: ₦40,000

This is a significant out-of-pocket expense that many enrollees don't anticipate.

3. Dialysis for Acute Renal Failure

Dialysis is partially covered for acute renal failure, with a maximum of 6 sessions. Beyond this limit, or for chronic kidney disease, you'll bear the full cost.

4. Eyeglasses Beyond ₦10,000

If your prescribed glasses cost more than ₦10,000, you pay the difference. Contact lenses are fully excluded.

5. Dental Procedures Beyond Basic Care

While NHIS covers basic dental care, advanced procedures require out-of-pocket payment:

• Crowns and bridges
• Dental implants
• Teeth bleaching/whitening
• Orthodontic treatment (braces)
• Maxillo-facial surgeries

Example: A dental implant can cost ₦150,000–₦300,000 per tooth—fully out-of-pocket.

6. Specialist Treatments Beyond Defined Limits

Some specialist consultations and procedures have coverage limits. Once you exceed these limits, additional costs are yours to bear.

Total Exclusions: What NHIS Does Not Cover

The NHIS benefit package has a clear exclusion list. These conditions and procedures are not covered at all, meaning you'll pay 100% out-of-pocket:

1. Occupational/Industrial Injuries

Injuries covered under the Workmen Compensation Act are excluded from NHIS.

2. Injuries from Specific Causes

• Natural disasters (earthquakes, landslides)
• Conflicts, social unrest, riots, wars
• Epidemics
• Extreme sports (car racing, horse racing, polo, mountaineering, boxing, wrestling)

3. Terminal Illnesses and Cancers

While the NHIA Act added treatment for cancers to the benefit package, some sources still list terminal illnesses and cancers as exclusions under certain plans. This discrepancy highlights the importance of confirming coverage with your specific HMO.

4. Cosmetic and Elective Surgeries

• Cosmetic procedures (e.g., mammoplasty, liposuction)
• Transplant surgeries (organ transplants, open-heart surgery, neurosurgery except borehole, laminectomy)

5. Infertility Treatments

• Artificial insemination
• IVF (In Vitro Fertilization)
• ICSI (Intracytoplasmic Sperm Injection)

6. Advanced Dental Care

• Dentures beyond the four-tooth limit
• Crowns, bridges, implants
• Bleaching/whitening
• Root canal treatments beyond the two-session limit

7. Contact Lenses

Provision of contact lenses is fully excluded.

8. Drug Abuse and Addiction Treatment

Treatment for drug abuse/addiction is not covered.

9. Domiciliary (Home) Visits

Home visits by healthcare providers are excluded.

10. Anti-Tuberculosis Drugs

TB medications are excluded from the benefit package.

11. Congenital Abnormalities Requiring Advanced Surgery

Conditions like Tetralogy of Fallot (TOF), Atrial Septal Defect (ASD), and Ventricular Septal Defect (VSD) requiring advanced surgical procedures are excluded.

12. Post-Mortem Examinations

Autopsies and post-mortem examinations are not covered.

13. Experimental or Unproven Treatments

Treatments not recognized by Nigerian medical standards or still in trial phases are excluded.

14. Treatment Outside Nigeria

International medical tourism or treatment received outside Nigeria is not covered.

15. Injuries from Intentional Self-Harm

Injuries resulting from self-inflicted harm are excluded.

How to Minimize Out-of-Pocket Expenses

While NHIS provides substantial coverage, here are practical steps to reduce your out-of-pocket spending:

1. Use Accredited Healthcare Providers

NHIS only covers services at accredited facilities. Going to non-accredited hospitals means you'll pay 100% out-of-pocket.

2. Stay Within the NHIS Essential Medicines List

Ask your doctor to prescribe medications on the NHIS Essential Medicines List to ensure coverage. Non-listed drugs may not be covered.

3. Confirm Coverage Before Expensive Procedures

Before undergoing high-cost procedures like CT scans, MRIs, or surgeries, confirm with your HMO what percentage is covered and what you'll pay.

4. Consider Supplemental Health Insurance

Many Nigerians purchase additional private health insurance or HMO plans to cover exclusions like dental implants, IVF, or international treatment.

5. Budget for the 10% Drug Co-Payment

If you're on chronic medications, set aside a monthly budget for the 10% co-payment. Over a year, this can range from ₦5,000 to ₦50,000+ depending on your condition.

6. Leverage ToolBase Resources

Use ToolBase's NHIS Contribution Calculator to estimate your monthly deductions and plan your household budget accordingly. You can also explore our Healthcare Cost Tracker to monitor out-of-pocket expenses throughout the year.

Common Misconceptions About NHIS Coverage

Let's clear up some frequent misunderstandings:

Misconception 1: "NHIS Covers Everything"

Reality: NHIS covers a comprehensive benefit package, but there are significant exclusions and co-payments. Always check the exclusion list before assuming coverage.

Misconception 2: "I Don't Need to Pay Anything at the Hospital"

Reality: You'll pay 10% of drug costs and 50% of high-technology investigations (unless it's a life-threatening emergency).

Misconception 3: "My HMO Will Cover Cosmetic Surgery"

Reality: Cosmetic procedures are fully excluded. If you want coverage for these, you'll need a separate plan.

Misconception 4: "NHIS Covers My Entire Family Without Limits"

Reality: Coverage extends to one spouse and up to four children under 18 for formal sector enrollees. Additional dependents require separate enrollment.

Misconception 5: "Cancer Treatment Is Fully Covered"

Reality: While the NHIA Act added cancer treatment to the benefit package, some HMOs still list terminal illnesses and cancers as exclusions. Confirm with your specific provider.

NHIS vs. Private HMO Plans: What's the Difference?

Many Nigerians wonder whether to rely solely on NHIS or purchase additional private coverage. Here's a quick comparison:

Bottom line: NHIS provides essential coverage, but private HMOs can fill gaps—especially for dental, optical, and international care.

Recent Changes Under the NHIA Act (2022)

The National Health Insurance Authority Act, signed in May 2022, introduced several key changes:

1. Mandatory Enrollment: All Nigerians and legal residents must enroll in health insurance.
2. Expanded Benefit Package: Added coverage for cancer treatment, first hour of emergency care, and first 3 hours of stroke management.
3. Basic Minimum Package Enforcement: NHIA enforces a minimum package of health services across all schemes to ensure equity.
4. Free Healthcare for Indigent Citizens: The Act provides that indigent citizens enjoy free healthcare funded by federal, state, and local governments.
5. Penalties for Non-Compliance: Employers with 5+ staff must enroll employees, with penalties for non-compliance.

These changes aim to achieve Universal Health Coverage (UHC) in line with the UN Sustainable Development Goals by 2030.
