Answer:
S82.202A, S82.402A
Explanation:
X-rays are high frequency electromagnetic radiation, produced from the collision of electron beams with metals. This radiation cannot be perceived by the human eye as it is beyond the maximum frequency distinguished by human vision. It is important in medicine because it makes it possible to generate diagnoses through images. The capture of these images correspond to codes that are placed on the x-ray machine and correspond to a specific part of the body, the codes that correspond to the tibia and fibula are S82.202A and S82.402A.
