About ICD-9-CM 17.21
17.21 is an ICD-9-CM procedure code for laparoscopic bilateral repair of direct inguinal hernia with graft or prosthesis. 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 3 ICD-10-PCS codes, such as 0YUA47Z (Supplement Bilateral Inguinal Region with Autologous Tissue Substitute, Percutaneous Endoscopic Approach), 0YUA4JZ (Supplement Bilateral Inguinal Region with Synthetic Substitute, Percutaneous Endoscopic Approach) and 0YUA4KZ (Supplement Bilateral Inguinal Region with Nonautologous Tissue Substitute, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
