About ICD-9-CM 996.52
996.52 is an ICD-9-CM diagnosis code for mechanical complication due to graft of other tissue, not elsewhere classified. 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 T86.820 (Skin graft (allograft) rejection) and T86.821 (Skin graft (allograft) (autograft) failure). All of these are approximate matches, so review the record to pick the right one.
