Please help with the following:

POSTOP Diag: Distal tibia/fibula fracture, Salter Harris II tibia fracture with displacement and angulation.

PROCEDURE: ...C-arm was brought in. The fractures were visualized. The fractures were anatomically reduced and then a long leg cast was then applied. After placement of long leg cast, the reduction was reviewed. There was noted to be excellent position and alignment...

That is all that is in the operative report. Seems easy enough but I need help with CPT and diagnosis code.
