About T22.75

T22.75 is the ICD-10-CM diagnosis code for corrosion of third degree of shoulder. It belongs to category T22 (burn and corrosion of shoulder and upper limb, except wrist and hand), block T20-T25 (burns and corrosions of external body surface, specified by site) 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 T22.7 (corrosion of third degree of shoulder and upper limb, except wrist and hand), T22.75 is specifically for corrosion of third degree of shoulder. Related codes cover unspecified site (T22.70), forearm (T22.71), elbow (T22.72), upper arm (T22.73), axilla (T22.74), scapular region (T22.76) and multiple sites of shoulder and upper limb, except wrist and hand (T22.79).

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.
