Know How to Report ICD-9 Codes When Dates of Service Span ICD-10 Implementation Date

Published on Mon Jan 08, 2001

Question: How should we report diagnosis codes for claims that begin on dates of service before Oct. 1, 2013, but don't end until after Oct. 1? We're an inpatient facility.

Answer: CMS answers this question with Transmittal 950, released on Aug. 19, which breaks down how each various providers should report claims that span the ICD-10 implementation date.

Inpatient hospitals: Use the "through" date -- If the hospital's discharge and/or through date occurs on or after Oct. 1, 2013, then the whole claim will be billed with ICD-10 codes. Part B hospital services, outpatient hospitals, outpatient therapy, hospices, renal disease providers, and outpatient home health: You'll split the claim, so all ICD-9 codes remain on one claim and all ICD-10 codes remain on the other claim.
