About ICD-9-CM 802.23
802.23 is an ICD-9-CM diagnosis code for closed 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 S02.630A (Fracture of coronoid process of mandible, unspecified side, initial encounter for closed fracture), S02.631A (Fracture of coronoid process of right mandible, initial encounter for closed fracture) and S02.632A (Fracture of coronoid process of left mandible, initial encounter for closed fracture). All of these are approximate matches, so review the record to pick the right one.
