About ICD-9-CM 16.01

16.01 is an ICD-9-CM procedure code for orbitotomy with bone flap. 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 6 ICD-10-PCS codes, such as 0NRP07Z (Replacement of Right Orbit with Autologous Tissue Substitute, Open Approach), 0NRP37Z (Replacement of Right Orbit with Autologous Tissue Substitute, Percutaneous Approach) and 0NRP47Z (Replacement of Right Orbit with Autologous Tissue Substitute, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
