About ICD-9-CM 16.51

16.51 is an ICD-9-CM procedure code for exenteration of orbit with removal of adjacent structures. 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 8 ICD-10-PCS codes, such as 08T0XZZ (Resection of Right Eye, External Approach), 08T1XZZ (Resection of Left Eye, External Approach) and 0NBP0ZZ (Excision of Right Orbit, Open 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.
