About ICD-9-CM 78.94
78.94 is an ICD-9-CM procedure code for insertion of bone growth stimulator, carpals and metacarpals. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-PCS codes, such as 0PHY0MZ (Insertion of Bone Growth Stimulator into Upper Bone, Open Approach), 0PHY3MZ (Insertion of Bone Growth Stimulator into Upper Bone, Percutaneous Approach) and 0PHY4MZ (Insertion of Bone Growth Stimulator into Upper Bone, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
