About ICD-9-CM 090.5
090.5 is an ICD-9-CM diagnosis code for other late congenital syphilis, symptomatic. 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 A50.52 (Hutchinson's teeth), A50.57 (Syphilitic saddle nose) and A50.59 (Other late congenital syphilis, symptomatic). All of these are approximate matches, so review the record to pick the right one.
