About coding Osteopenia borderline

The ICD-10-CM code for Osteopenia borderline is M85.8 (Other specified disorders of bone density and structure).

Within M85, choose M85.8 (Other specified disorders of bone density and structure) only when documentation doesn't support a more specific option: fibrous dysplasia (monostotic) (M85.0), skeletal fluorosis (M85.1), hyperostosis of skull (M85.2), Osteitis condensans (M85.3), Solitary bone cyst (M85.4), Aneurysmal bone cyst (M85.5), other cyst of bone (M85.6) and disorder of bone density and structure, unspecified (M85.9).

To report this condition, pick the subcode that matches the documentation: M85.80 (unspecified site), M85.81 (shoulder), M85.82 (upper arm), M85.83 (forearm), M85.84 (hand), M85.85 (thigh), M85.86 (lower leg), M85.87 (ankle and foot) and 2 more.

Don't report M85.8 together with the conditions in its Excludes1 note: diffuse idiopathic skeletal hyperostosis [DISH] (M48.1), osteosclerosis congenita (Q77.4), osteosclerosis fragilitas (generalista) (Q78.2) and osteosclerosis myelofibrosis (D75.81).
