About coding radius fracture

The ICD-10-CM code for radius fracture is M84.43 (Pathological fracture, ulna and radius).

Within M84.4 (pathological fracture, not elsewhere classified), M84.43 is specifically for pathological fracture, ulna and radius. Related codes cover unspecified site (M84.40), shoulder (M84.41), humerus (M84.42), hand and fingers (M84.44), femur and pelvis (M84.45), tibia and fibula (M84.46), ankle, foot and toes (M84.47) and other site (M84.48).

Codes in this range require a 7th character: A for initial encounter for 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 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.
