S82.51XQ vs S82.87
S82.51XQ (Displaced fracture of medial malleolus of right tibia, subsequent encounter for open fracture type I or II with malunion) compared with S82.87 (Pilon fracture of tibia), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. S82.51XQ carries an Excludes1 note covering S82.87: “pilon fracture of distal tibia (S82.87-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
