About ICD-9-CM 802.33
802.33 is an ICD-9-CM diagnosis code for open fracture of mandible, coronoid process. 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 S02.630B (Fracture of coronoid process of mandible, unspecified side, initial encounter for open fracture), S02.631B (Fracture of coronoid process of right mandible, initial encounter for open fracture) and S02.632B (Fracture of coronoid process of left mandible, initial encounter for open fracture). All of these are approximate matches, so review the record to pick the right one.
