About ICD-9-CM 906.0
906.0 is an ICD-9-CM diagnosis code for late effect of open wound of head, neck, and trunk. 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 5 ICD-10-CM codes, such as S01.90XS (Unspecified open wound of unspecified part of head, sequela), S11.90XS (Unspecified open wound of unspecified part of neck, sequela) and S21.90XS (Unspecified open wound of unspecified part of thorax, sequela). All of these are approximate matches, so review the record to pick the right one.
