About ICD-9-CM 33.52
33.52 is an ICD-9-CM procedure code for bilateral lung transplantation. 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 0BYM0Z0 (Transplantation of Bilateral Lungs, Allogeneic, Open Approach), 0BYM0Z1 (Transplantation of Bilateral Lungs, Syngeneic, Open Approach) and 0BYM0Z2 (Transplantation of Bilateral Lungs, Zooplastic, Open Approach). All of these are approximate matches, so review the record to pick the right one.
