About ICD-9-CM 824.9

824.9 is an ICD-9-CM diagnosis code for unspecified fracture of ankle, open. 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 S82.899B (Other fracture of unspecified lower leg, initial encounter for open fracture type I or II) and S82.899C (Other fracture of unspecified lower leg, initial encounter for open fracture type IIIA, IIIB, or IIIC). All of these are approximate matches, so review the record to pick the right one.
