Questions About 0SG637Z

Is 0SG637Z still a valid ICD-10-PCS code?

No. 0SG637Z 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 0SG637Z?

The CMS ICD-10-PCS conversion table maps 0SG637Z to 0SB63ZZ. Confirm it matches the procedure documentation before you use it; a conversion is a starting point, not an automatic substitution.

Can I still use 0SG637Z for older discharges?

Yes, for inpatient discharges from October 1, 2019 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 0SG637Z.
