About ICD-9-CM 812.12

812.12 is an ICD-9-CM diagnosis code for open fracture of anatomical neck of humerus. 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 2 ICD-10-CM codes, such as S42.293B (Other displaced fracture of upper end of unspecified humerus, initial encounter for open fracture) and S42.296B (Other nondisplaced fracture of upper end of unspecified humerus, initial encounter for open fracture). All of these are approximate matches, so review the record to pick the right one.
