944.45 — Deep necrosis of underlying tissues [deep third degree] without mention of loss of a body part, of palm of hand

944.45 is an ICD-9-CM diagnosis code for deep necrosis of underlying tissues [deep third degree] without mention of loss of a body part, of palm of hand. 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 T23.359A (Burn of third degree of unspecified palm, initial encounter) and T23.759A (Corrosion of third degree of unspecified palm, initial encounter). All of these are approximate matches, so review the record to pick the right one.
