About ICD-9-CM E929.5

E929.5 is an ICD-9-CM diagnosis code for late effects of accident due to natural and environmental factors. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as W92.XXXS (Exposure to excessive heat of man-made origin, sequela), W99.XXXS (Exposure to other man-made environmental factors, sequela) and X39.8XXS (Other exposure to forces of nature, sequela). All of these are approximate matches, so review the record to pick the right one.
