The preexisting condition look-back period is measured in months. Which of the following is a valid look-back month for health policy preexisting condition determination?

• A. Twelve
• B. Six
• C. Three
• D. Nine

Answer: (B)

The concept being tested is how long before the policy starts is used to check for conditions that existed prior to coverage. This look-back period is measured in months, and in health policy practice questions the standard window used is six months. So, a condition diagnosed or treated within the six months leading up to the policy’s effective date would be considered preexisting under this framework. That’s why six months is the valid look-back period in this context. The other durations—twelve, three, or nine months—aren’t the standard look-back window used for this determination in the question’s framework.
