About S53.30

S53.30 is the ICD-10-CM diagnosis code for traumatic rupture of unspecified ulnar collateral ligament. It belongs to category S53 (dislocation and sprain of joints and ligaments of elbow), block S50-S59 (injuries to the elbow and forearm) 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 S53.3, choose S53.30 (unspecified ulnar collateral ligament) only when documentation doesn't support a more specific option: right ulnar collateral ligament (S53.31) and left ulnar collateral ligament (S53.32).

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.
