Questions About XW03377

Is XW03377 still a valid ICD-10-PCS code?

No. XW03377 was deleted from ICD-10-PCS effective October 1, 2026, with the FY 2027 code set. It cannot be reported for inpatient discharges on or after that date.

What replaced XW03377?

The CMS ICD-10-PCS conversion table maps XW03377 to 3E033GC. Confirm it matches the procedure documentation before you use it; a conversion is a starting point, not an automatic substitution.

Can I still use XW03377 for older discharges?

Yes, for inpatient discharges from October 1, 2021 through September 30, 2026. 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 XW03377.
