Morbidity Rate

Morbidity rate is a statistical measure used by insurers and health professionals to indicate the frequency or likelihood of illness, injury, or disability within a defined population over a specific period of time. It reflects how many people in a given group are expected to experience a health-related event that may result in medical costs or lost productivity. In the insurance industry, morbidity rates are used to predict claim patterns, set premium levels, and design sustainable health and disability products.

Insurers use large-scale health data and actuarial analysis to estimate morbidity rates based on age, gender, occupation, lifestyle, and other risk factors. A higher morbidity rate indicates a greater likelihood of claims, which generally leads to higher premiums. Morbidity rates differ from mortality rates, which measure the frequency of death, as they focus on the probability of becoming ill or disabled rather than dying.

Example:

If data shows that 10 out of every 1,000 people in a specific age group experience a long-term disability each year, the morbidity rate for that group is 1 percent. Insurers use this information to calculate premiums and reserves for disability coverage.

What to Watch For:

Morbidity rates can change over time due to improvements in healthcare, changes in lifestyle habits, or shifts in workforce demographics. Understanding how morbidity affects insurance pricing helps explain why premiums may rise with age or why certain occupations have higher disability insurance costs.

Mortality Rate

Mortality rate is a statistical measure that represents the frequency or probability of death within a specific population during a defined period of time. In insurance, it is a key actuarial factor used to determine life insurance premiums, reserves, and the expected financial risk to the insurer. Mortality rates are derived from large-scale data that reflect age, gender, health, lifestyle, and other risk factors, allowing insurers to predict how many people in a given group are likely to die each year.

Medically Underwritten (MU)

Medically underwritten (MU) refers to the process used by insurers to evaluate an applicant’s health history before approving coverage and determining eligibility, premiums, and benefit limits. In a medically underwritten plan, you must answer health questions, disclose pre-existing conditions, and often complete a medical questionnaire or provide additional documentation

Major Restorative

Major restorative coverage includes complex dental procedures designed to restore the function and appearance of teeth. Examples include crowns, bridges, onlays, dentures, and sometimes implants. These treatments are more extensive and expensive than basic restorative services such as fillings.

Misstatement of Age

Misstatement of age occurs when the age of the insured person is recorded incorrectly on an insurance application or policy. Because age is a key factor in determining eligibility, premiums, and benefit amounts, any error - whether accidental or intentional - can affect the terms of coverage. The misstatement may be discovered during underwriting, at the time of a claim, or during a policy review.

Medically Necessary

Medically necessary describes any service, treatment, or supply required to diagnose, treat, or manage a health condition, rather than for convenience, appearance, or personal preference. Insurers use this term to determine whether a claim qualifies for payment under your policy.
