About coding stress fracture

The ICD-10-CM code for stress fracture is M84.30 (Stress fracture, unspecified site). The official index lists 22 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M84.30.

Within M84.3, choose M84.30 (unspecified site) only when documentation doesn't support a more specific option: shoulder (M84.31), humerus (M84.32), ulna and radius (M84.33), hand and fingers (M84.34), pelvis and femur (M84.35), tibia and fibula (M84.36), ankle, foot and toes (M84.37) and other site (M84.38).

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.
