I am having a family floater health insurance policy since 2017, in 2017 itself after taking the policy I have surgery to remove swelled lymph node in my neck (Benign in nature) which my insurer didn't cover (Obviously)

Like to know do I need to intimate the insurer regarding the same while renewing?? (As they do not ask any question while renewing)

Will it affect any of my future claims?

If yes, do I need to mail the customer care regarding that?
