<prompt> Human: I visited the hospital on December 1st. My health insurance deductible is 1500 for the year. The claim email from my insurance just came in today and said the hospital bill was 3800. If I pay my insurance bill on January 5th, will the 1500 I pay to my insurance deductible be for 2016 or 2017?  <response>: Everything is based on dates of service and the start and end dates of the plan year. Not all plans use a calendar year, but most do. So that will count for 2016.
