Insurance - marked out paitent was told I was staying the nite

Have your surgeon submit a revised order to insurance - seems to be his/her error, and should just require an amended order. You should not be penalized for a paperwork screw-up, but also don't waste your recovery energy worrying about this - it will get straightened out. Often docs order 23 hour obs for this type of surgery, assuming you will be discharged within that 23 hour time period - thus technically “out-patient" but since you exceeded 24 hours you are considered in-patient. Try not to be upset or worried, but call your surgeon's insurance specialist and let them know.
