How long should it take an insurance company to come back to you with a decision on your long term claim before they ask for more info and tell you the next step?

This can depend on a number of different things, including the terms of your specific policy, whether your application was considered "complete" when it was submitted, whether the insurer has asked for additional information, and so on. That said, if it's been more than 60 days, you should contact our firm, as it may be time to connect you with a lawyer for a free consultation.
