Questions About DDY5KZZ

Is DDY5KZZ still a valid ICD-10-PCS code?

No. DDY5KZZ 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 DDY5KZZ?

The CMS ICD-10-PCS conversion table maps DDY5KZZ to 0D5E0Z3, 0D5E3Z3, and 0D5E4Z3. Pick the one that matches the procedure documentation; a conversion is a starting point, not an automatic substitution.

Can I still use DDY5KZZ 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 DDY5KZZ.
