S83.5Sprain of cruciate ligament of knee

S83.5 is the ICD-10-CM diagnosis code for sprain of cruciate ligament of knee. It belongs to category S83 (dislocation and sprain of joints and ligaments of knee), 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 S83 (dislocation and sprain of joints and ligaments of knee), S83.5 is specifically for sprain of cruciate ligament of knee. Related codes cover subluxation and dislocation of patella (S83.0), subluxation and dislocation of knee (S83.1), tear of meniscus, current injury (S83.2), tear of articular cartilage of knee, current (S83.3), sprain of collateral ligament of knee (S83.4), sprain of the superior tibiofibular joint and ligament (S83.6), sprain of other specified parts of knee (S83.8) and sprain of unspecified site of knee (S83.9).

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.
