About ICD-9-CM 055.79
055.79 is an ICD-9-CM diagnosis code for measles with other specified complications. 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 B05.1 (Measles complicated by meningitis), B05.4 (Measles with intestinal complications) and B05.89 (Other measles complications). All of these are approximate matches, so review the record to pick the right one.
