ICD Code M85.9

ICD code M85.9 is a diagnosis used when a patient has an abnormality in bone density or structure, but the specific type of disorder is not specified.

1. Patient presents with abnormal bone density or structure identified through imaging studies (e.g., X-ray, DEXA scan)

2. No specific underlying bone disorder (such as osteoporosis, osteomalacia, or Paget’s disease) can be definitively diagnosed

3. Clinical symptoms may include unexplained bone pain, increased risk of fractures, or skeletal deformities

4. Laboratory tests and clinical evaluation do not reveal a more specific etiology for the bone abnormality

5. The bone disorder does not fit the criteria for any other specified bone density or structural disorder

6. The diagnosis is based on exclusion after thorough assessment and workup

- 77081: Dual-energy X-ray absorptiometry (DXA), bone density study, 1 or more sites; appendicular skeleton (peripheral) (e.g., radius, wrist, heel)

- 20220: Bone biopsy, trocar or needle; superficial

- 20225: Bone biopsy, trocar or needle; deep

- 20680: Removal of implant; deep (e.g., buried wire, pin, screw, metal band, nail, rod or plate)
