About ICD-9-CM 996.49
996.49 is an ICD-9-CM diagnosis code for other mechanical complication of other internal orthopedic 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 4 ICD-10-CM codes, such as T84.119A (Breakdown (mechanical) of internal fixation device of unspecified bone of limb, initial encounter), T84.129A (Displacement of internal fixation device of unspecified bone of limb, initial encounter) and T84.199A (Other mechanical complication of internal fixation device of unspecified bone of limb, initial encounter). All of these are approximate matches, so review the record to pick the right one.
