About ICD-9-CM 20.98

20.98 is an ICD-9-CM procedure code for implantation or replacement of cochlear prosthetic device, multiple 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 18 ICD-10-PCS codes, such as 09HD06Z (Insertion of Multiple Channel Cochlear Prosthesis into Right Inner Ear, Open Approach), 09HD06Z (Insertion of Multiple Channel Cochlear Prosthesis into Right Inner Ear, Open Approach) and 09HD36Z (Insertion of Multiple Channel Cochlear Prosthesis into Right Inner Ear, Percutaneous 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.
