About ICD-9-CM 37.53

37.53 is an ICD-9-CM procedure code for replacement or repair of thoracic unit of (total) replacement heart system. 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 02RK0JZ (Replacement of Right Ventricle with Synthetic Substitute, Open Approach), 02RL0JZ (Replacement of Left Ventricle with Synthetic Substitute, Open Approach) and 02WA0JZ (Revision of Synthetic Substitute in Heart, 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.
