S88.021Partial traumatic amputation at knee level, right lower leg

S88.021 is the ICD-10-CM diagnosis code for partial traumatic amputation at knee level, right lower leg. It belongs to category S88 (traumatic amputation of lower leg), block S80-S89 (injuries to the knee and lower leg) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within S88.02 (partial traumatic amputation at knee level), S88.021 is specifically for partial traumatic amputation at knee level, right lower leg. Related codes cover left lower leg (S88.022) and unspecified lower leg (S88.029).

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.
