About M80.86

M80.86 is the ICD-10-CM diagnosis code for other osteoporosis with current pathological fracture, lower leg. It belongs to category M80 (osteoporosis with current pathological fracture), block M80-M85 (disorders of bone density and structure) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within M80.8 (other osteoporosis with current pathological fracture), M80.86 is specifically for other osteoporosis with current pathological fracture, lower leg. Related codes cover unspecified site (M80.80), pathological fracture, shoulder (M80.81), humerus (M80.82), forearm (M80.83), hand (M80.84), femur (M80.85), ankle and foot (M80.87), vertebra(e) (M80.88) and 2 more.

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.

Use an additional code to identify major osseous defect, if applicable (M89.7-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
