About ICD-9-CM 996.63
996.63 is an ICD-9-CM diagnosis code for infection and inflammatory reaction due to nervous system device, implant, and graft. 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 7 ICD-10-CM codes, such as T85.730A (Infection and inflammatory reaction due to ventricular intracranial (communicating) shunt, initial encounter), T85.731A (Infection and inflammatory reaction due to implanted electronic neurostimulator of brain, electrode (lead), initial encounter) and T85.732A (Infection and inflammatory reaction due to implanted electronic neurostimulator of peripheral nerve, electrode (lead), initial encounter). All of these are approximate matches, so review the record to pick the right one.
