About W93.01XS
W93.01XS is the ICD-10-CM diagnosis code for contact with dry ice, sequela. It belongs to category W93 (exposure to excessive cold of man-made origin), block W85-W99 (exposure to electric current, radiation and extreme ambient air temperature and pressure) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E929.5 (late effects of accident due to natural and environmental factors).
