S62.2Fracture of first metacarpal bone

S62.2 is the ICD-10-CM diagnosis code for fracture of first metacarpal bone. 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 7 subcodes must be used instead.

Within S62 (fracture at wrist and hand level), S62.2 is specifically for fracture of first metacarpal bone. Related codes cover fracture of navicular [scaphoid] bone of wrist (S62.0), fracture of other and unspecified carpal bone(s) (S62.1), fracture of other and unspecified metacarpal bone (S62.3), fracture of thumb (S62.5), fracture of other and unspecified finger(s) (S62.6) and unspecified fracture of hand (S62.9).

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.
