About ICD-9-CM 996.59
996.59 is an ICD-9-CM diagnosis code for mechanical complication due to other implant and internal device, 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 4 ICD-10-CM codes, such as T85.398A (Other mechanical complication of other ocular prosthetic devices, implants and grafts, initial encounter), T85.590A (Other mechanical complication of bile duct prosthesis, initial encounter) and T85.692A (Other mechanical complication of permanent sutures, initial encounter). All of these are approximate matches, so review the record to pick the right one.
