Which of the following is NOT classified as an unfair claims settlement practice?

Denying unsubstantiated claims on a timely basis is not classified as an unfair claims settlement practice because it reflects a legitimate action by the insurer in maintaining the integrity of the claims process. Insurance companies are obligated to investigate claims thoroughly and ensure that they are legitimate before providing benefits. If a claim lacks sufficient evidence or documentation to support it, denying that claim is not only appropriate but also necessary to prevent fraudulent activity and protect the insurer and its policyholders.

In contrast, failing to acknowledge pertinent communications, not providing a reasonable explanation for a denial, and failing to finalize the investigation of claims can be seen as unfair practices because these actions can lead to unnecessary delays, confusion, and frustration for policyholders. Clear communication and timely processing are fundamental responsibilities of insurers, ensuring that policyholders receive fair treatment throughout the claims process.
