Questions About XW043E6

Is XW043E6 still a valid ICD-10-PCS code?

No. XW043E6 was deleted from ICD-10-PCS effective October 1, 2025, with the FY 2026 code set. It cannot be reported for inpatient discharges on or after that date.

What replaced XW043E6?

The CMS ICD-10-PCS conversion table lists no replacement for XW043E6. Build the current code from the ICD-10-PCS tables or find it through the Alphabetic Index, then confirm it against the procedure documentation.

Can I still use XW043E6 for older discharges?

Yes, for inpatient discharges from October 1, 2021 through September 30, 2025. 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 XW043E6.
