M79.66 requires a 6th digit:
M79.661 Pain in right lower leg
M79.662 Pain in left lower leg
If the patient has bilateral lower leg pain, you'd use both of those codes to indicate left and right.
M79.661 Pain in right lower leg
M79.662 Pain in left lower leg
If the patient has bilateral lower leg pain, you'd use both of those codes to indicate left and right.
