About ICD-9-CM 31.98
31.98 is an ICD-9-CM procedure code for other operations on larynx. 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 24 ICD-10-PCS codes, such as 0C7S0DZ (Dilation of Larynx with Intraluminal Device, Open Approach), 0C7S0ZZ (Dilation of Larynx, Open Approach) and 0C7S3DZ (Dilation of Larynx with Intraluminal Device, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
