About ICD-9-CM 844.8

844.8 is an ICD-9-CM diagnosis code for sprains and strains of other specified sites of knee and leg. 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 S83.8X9A (Sprain of other specified parts of unspecified knee, initial encounter) and S86.819A (Strain of other muscle(s) and tendon(s) at lower leg level, unspecified leg, initial encounter). All of these are approximate matches, so review the record to pick the right one.
