When it comes to employee health benefits in the Philippines, understanding pre-existing conditions and how they affect coverage is crucial — especially if you’re exploring HMO options for an entire team. In this guide, we break down everything HR teams and employees need to know, from definitions to practical tips for choosing the right plan.

What are Pre-Existing Conditions?

In the context of HMOs, pre-existing conditions refer to any illness, disease, or medical condition that existed before an individual enrolled in a health plan. Insurers often look at these conditions to determine coverage, waiting periods, and benefits.

Common examples of pre-existing conditions include:

Hypertension (high blood pressure)
Diabetes
Asthma
Thyroid conditions
Dyslipidemia
Polycystic Ovary Syndrome (PCOS)
Other chronic conditions that require ongoing management

Even if a condition is kept under control or if a member is already undergoing maintenance for it, HMOs may still consider it a pre-existing condition. Understanding this helps HR teams plan for comprehensive coverage that fits their employees’ needs.

Why Do HMOs Check for Pre-Existing Conditions?

HMOs in the Philippines conduct checks for pre-existing conditions primarily to manage risk and healthcare costs. These evaluations help insurers anticipate potential claims and maintain sustainability for all members.

How Are Pre-Existing Conditions Evaluated?

Health Questionnaires: Employees may be asked to fill out detailed forms about their medical history.
Annual Physical Exams (APE) or Pre-Employment Medical Examinations (PME or PEME): Results provide objective data about current health status.
Doctor Assessments & Past Medical Records: Some plans may request reports to verify conditions.

Some HMOs may also ask for health declarations to ensure transparency. Accurate declarations protect employees from future claim denials and ensure the plan can provide the right support for their needs.

Are Pre-Existing Conditions Covered by HMOs?

Coverage of pre-existing conditions varies depending on the HMO plan in the Philippines. Most plans offer partial coverage, full coverage after evaluation, or limited coverage depending on the condition and plan terms.

Waiting Periods

For some HMOs, pre-existing conditions may not be covered immediately. A waiting period is the time you must wait after enrollment before coverage for pre-existing conditions kicks in. In the Philippines, waiting periods typically range from 6 months to 2 years, depending on the type of condition and the HMO provider.

Partial vs. Excluded Coverage

Partially covered: Some conditions may be partially reimbursed or have caps or set limits during the waiting period.
Excluded: Certain conditions may not be covered at all if they pose high risk.
Coverage limits: Many HMOs may offer coverage once the condition is reviewed by a medical professional, but set a maximum reimbursement amount for chronic conditions.
Maximum Benefit Limits (MBL): Coverage may be limited up to the plan’s annual MBL.

Understanding these nuances before choosing an HMO helps the HRs understand the coverage plan, and thus helps employees avoid surprises when filing for claims. HR teams should carefully review plan documents to understand these limits and communicate them clearly to employees.

What Happens If You Don’t Declare a Pre-Existing Condition?

Failing to declare a pre-existing condition can lead to consequences:

Claims investigation: Insurers may review medical records and investigate discrepancies.
Risks of non-disclosure: Denied claims, delayed reimbursements, or even plan cancellation.

Honest disclosure is always the safest choice, especially when it comes to health. It ensures that employees receive the care they need and protects the company from liability.

Tips for Employees and HR Teams When Choosing an HMO Plan

Selecting the right HMO plan requires careful consideration. Here are some practical tips:

Ask About Pre-Existing Coverage: Clarify which conditions are covered, waiting periods, and partial vs. full benefits.
Compare Plans: Look at the maximum benefit limits, coverage inclusions, and all exclusions .
Prioritize Digital Access: Platforms that offer teleconsultations and online LOAs save time and improve care management for employees with chronic conditions.
Check Telehealth Options: Quick access to online doctors ensures employees get timely diagnosis, prescriptions, and care without long hospital waits.
Consider Employee Needs: Evaluate which conditions are common in your workforce and choose plans that provide appropriate support.
