Common questions

What belongs in the tracker?

Add every dated claim event that may show filing, notice, investigation activity, treatment, a response, or a written decision.

Does under investigation mean the claim is denied?

No. It is a status description. Use the actual written notice to record what is pending or disputed.

Why does the tool avoid deadline math?

The trigger, service facts, statutory period, and exceptions can require review of the actual documents.
