Questions About 5A0522C

Is 5A0522C still a valid ICD-10-PCS code?

No. 5A0522C 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 5A0522C?

The CMS ICD-10-PCS conversion table maps 5A0522C to 5A0222C. Confirm it matches the procedure documentation before you use it; a conversion is a starting point, not an automatic substitution.

Can I still use 5A0522C 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 5A0522C.
