M81Osteoporosis without current pathological fracture

M81 is the ICD-10-CM diagnosis code for osteoporosis without current pathological fracture. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: M81.0 (fracture), M81.6 ([Lequesne]) and M81.8 (fracture).

Don't report M81 together with the conditions in its Excludes1 note: osteoporosis with current pathological fracture (M80.-) and Sudeck's atrophy (M89.0).

Use an additional code to identify: major osseous defect, if applicable (M89.7-) and personal history of (healed) osteoporosis fracture, if applicable (Z87.310).

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