S53.0Subluxation and dislocation of radial head
S53.0 is a header code, so it can't be reported by itself. Choose one of the 5 more specific codes beneath it and add the required 7th character.

About S53.0
S53.0 is the ICD-10-CM diagnosis code for subluxation and dislocation of radial head. 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 5 subcodes must be used instead.
Within S53 (dislocation and sprain of joints and ligaments of elbow), S53.0 is specifically for subluxation and dislocation of radial head. Related codes cover subluxation and dislocation of ulnohumeral joint (S53.1), traumatic rupture of radial collateral ligament (S53.2), traumatic rupture of ulnar collateral ligament (S53.3) and sprain of elbow (S53.4).
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.
Don't report S53.0 together with the conditions in its Excludes1 note: Monteggia's fracture-dislocation (S52.27-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
