ICD-9-CM procedure code (retired)
33.6 — Combined heart-lung transplantation
About ICD-9-CM 33.6
33.6 is an ICD-9-CM procedure code for combined heart-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 6 ICD-10-PCS codes, such as 02YA0Z0 (Transplantation of Heart, Allogeneic, Open Approach), 02YA0Z1 (Transplantation of Heart, Syngeneic, Open Approach) and 02YA0Z2 (Transplantation of Heart, Zooplastic, 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.
