824.1 — Fracture of medial malleolus, open
About ICD-9-CM 824.1
824.1 is an ICD-9-CM diagnosis code for fracture of medial malleolus, 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 4 ICD-10-CM codes, such as S82.53XB (Displaced fracture of medial malleolus of unspecified tibia, initial encounter for open fracture type I or II), S82.53XC (Displaced fracture of medial malleolus of unspecified tibia, initial encounter for open fracture type IIIA, IIIB, or IIIC) and S82.56XB (Nondisplaced fracture of medial malleolus of unspecified tibia, initial encounter for open fracture type I or II). All of these are approximate matches, so review the record to pick the right one.
