CMS states:
ICD-10 codes must be used on all HIPAA transactions, including outpatient claims with dates of service, and inpatient claims with dates of discharge on and after October 1, 2013.
My question is: Where is the discharge date in the 837I? I only find discharge hour. Is the Through date of statement date to be assumed to be discharge date? For interim bills, that would not be valid. Please advise what date in the 837I should be used for DX and Principal/Other Procedure codes, for ICD-10
The date of discharge would be the through date from the Statement Dates segment for final bills unless Occurrence Code 42 (Date of Discharge) is used, in that case you would use the Occurrence Date that corresponds to that Occurrence Code.
For interim billing, the through date from the Statement Dates segment represents the end of the billing period. ICD reporting for all new interim claims should use ICD-10 if the interim is issued after the compliance date, even if the initial claim began with ICD-9. ICD10 would also be used if the interim claim spanned the compliance date.
