943.55 — Deep necrosis of underlying tissues [deep third degree] with loss of a body part, of shoulder

943.55 is an ICD-9-CM diagnosis code for deep necrosis of underlying tissues [deep third degree] with loss of a body part, of shoulder. 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 T22.359A (Burn of third degree of unspecified shoulder, initial encounter) and T22.759A (Corrosion of third degree of unspecified shoulder, initial encounter). All of these are approximate matches, so review the record to pick the right one.
