About coding knee contusion
The ICD-10-CM code for knee contusion is S80.0 (Contusion of knee).
Within S80 (superficial injury of knee and lower leg), S80.0 is specifically for contusion of knee. Related codes cover contusion of lower leg (S80.1), other superficial injuries of knee (S80.2), other superficial injuries of lower leg (S80.8) and unspecified superficial injury of knee and lower leg (S80.9).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
