Health insurance rejection because hospital registration expired?

I had a maternity claim for my delivery through c section that was performed in a maternity nursing home. I paid for the delivery and am expecting a reimbursement from insurance. I have submitted all my documents, but the hospital registration lapsed in February. I was admitted in July. The insurance company has asked for renewed registration but the hospital is not able to provide it.

Will my claim be rejected on this basis? In that case what can I do?
