944.23 is an ICD-9-CM diagnosis code for Blisters, epidermal loss [second degree] of two or more digits of hand, not including thumb. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as T23.239A (Burn of second degree of unspecified multiple fingers (nail), not including thumb, initial encounter) and T23.639A (Corrosion of second degree of unspecified multiple fingers (nail), not including thumb, initial encounter). All of these are approximate matches, so review the record to pick the right one.
