ICD-9-CM procedure code (retired)
20.97 — Implantation or replacement of cochlear prosthetic device, single channel
About ICD-9-CM 20.97
20.97 is an ICD-9-CM procedure code for implantation or replacement of cochlear prosthetic device, single channel. 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 12 ICD-10-PCS codes, such as 09HD05Z (Insertion of Single Channel Cochlear Prosthesis into Right Inner Ear, Open Approach), 09HD35Z (Insertion of Single Channel Cochlear Prosthesis into Right Inner Ear, Percutaneous Approach) and 09HD45Z (Insertion of Single Channel Cochlear Prosthesis into Right Inner Ear, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
