About S50.34

S50.34 is the ICD-10-CM diagnosis code for external constriction of elbow. It belongs to category S50 (superficial injury of elbow and forearm), 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 S50.3 (other superficial injuries of elbow), S50.34 is specifically for external constriction of elbow. Related codes cover abrasion of elbow (S50.31), Blister (nonthermal) of elbow (S50.32), superficial foreign body of elbow (S50.35), insect bite (nonvenomous) of elbow (S50.36) and other superficial bite of elbow (S50.37).

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.
