Questions About DFY2KZZ

Is DFY2KZZ still a valid ICD-10-PCS code?

No. DFY2KZZ was deleted from ICD-10-PCS effective October 1, 2022, with the FY 2023 code set. It cannot be reported for inpatient discharges on or after that date.

What replaced DFY2KZZ?

The CMS ICD-10-PCS conversion table maps DFY2KZZ to 0F550Z3, 0F553Z3, 0F554Z3, and 0F560Z3 and 20 more codes. Pick the one that matches the procedure documentation; a conversion is a starting point, not an automatic substitution.

Can I still use DFY2KZZ for older discharges?

Yes, for inpatient discharges from October 1, 2019 through September 30, 2022. ICD-10-PCS codes are assigned by the code set in effect on the date of discharge, so a corrected or late claim for a discharge in that window still uses DFY2KZZ.
