S62.18Fracture of trapezoid [smaller multangular]

S62.18 is the ICD-10-CM diagnosis code for fracture of trapezoid [smaller multangular]. It belongs to category S62 (fracture at wrist and hand level), block S60-S69 (injuries to the wrist, hand and fingers) 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 6 subcodes must be used instead.

Within S62.1 (fracture of other and unspecified carpal bone(s)), S62.18 is specifically for fracture of trapezoid [smaller multangular]. Related codes cover unspecified carpal bone (S62.10), triquetrum [cuneiform] bone of wrist (S62.11), lunate [semilunar] (S62.12), capitate [os magnum] bone (S62.13), body of hamate [unciform] bone (S62.14), hook process of hamate [unciform] bone (S62.15), pisiform (S62.16) and trapezium [larger multangular] (S62.17).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion, P for subsequent encounter for fracture with malunion and 1 more. 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.
