You do not need to change or rewrite your original orders
By CMS.gov November 25, 2015
CMS wants to remind you not to change or rewrite your original orders for any service or product due to the change of code sets from ICD-9-CM to ICD-10-CM.
For any type of product or service prior to October 1, 2015, do not change the order, even if it will be a continued service with dates spanning prior and after ICD-10 is in effect. You will simply change your codes from ICD-9 to ICD-10, leaving the original order as is.
They do not require updated physician (or non-physician practitioner) orders for lab, radiology services, or any other services after ICD-10 implementation.
