Query of non settlement claim.
Hospital provide the printed bill with final settlement receipt but the detail of medicine was mention manually on supporting docs which is not acceptable by the raksha tpa company.

My question is bill and receipt from the hospital is provided to insurance company and proof of payment from inssured person is provided however still why such delayed?
