About ICD-9-CM 10.31
10.31 is an ICD-9-CM procedure code for excision of lesion or tissue of conjunctiva. 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 2 ICD-10-PCS codes, such as 08BSXZZ (Excision of Right Conjunctiva, External Approach) and 08BTXZZ (Excision of Left Conjunctiva, External Approach). All of these are approximate matches, so review the record to pick the right one.
