Which of the following terms is NOT related to healthcare costs?

The term that is not directly related to healthcare costs is the interest rate. In the context of healthcare, terms like out-of-pocket limit, co-payment, and deductible specifically refer to different components of health insurance and the costs that individuals incur when accessing medical care.

The out-of-pocket limit is the maximum amount that an insured individual would need to pay for covered healthcare services in a plan year. Once this limit is reached, the insurance company pays 100% of the covered costs.

Co-payment is a fixed amount that a patient pays for a specific healthcare service, such as a doctor's visit or prescription medication, at the time of receiving the service.

Deductible refers to the amount that a patient must pay out-of-pocket before their insurance coverage begins to pay for claims. These terms are foundational to understanding how healthcare costs are structured within insurance policies.

Interest rates, while related to financing and loans, do not pertain to the healthcare cost framework in the same way. They might affect the overall financial landscape but do not specifically categorize or describe healthcare expenses themselves.
