SOP Bulletin 178

ICD Coding:
  • ICD-9-CM Codes: 733.0
  • ICD-10-AM Codes: M80.0-M80.9, M81.0-M81.9, M82.0, M82.1, M82.8

This is general (systemic) low bone density.  This low bone density can be incidentally discovered by bone imaging, or discovered on investigation of a pathological bone fracture resulting from relatively trivial application of forces to the bone.

Is specific diagnostic evidence required to apply the SOP?Yes.

Confirmation of the diagnosis requires:

  • bone densitometry results, or
  • radiological evidence of a minimal trauma fracture associated with contemporary or previous imaging evidence of osteoporosis.

The threshold level for the determination of osteoporosis using bone densitometry is a measurement = 2.5 standard deviations below the mean compared to normal young adult sex-matched controls. This is the T-score rather than the associated Z-score, which is for age-matched controls.

The relevant medical specialist is an endocrinologist.

Are there sub-factors that require specific information? – No.
Additional diagnoses covered by SOP
  • Nil
Conditions excluded from SOP
  • A normal traumatic fracture.
  • Osteomalacia, ICD code 268.2
  • Osteopaenia, declared not a disease by RMA - NIF
  • Reduced bone density not meeting the minimum decrease in bone density requirement in the SOP - NIF
Unconfirmed diagnosis

If, after applying the above information, you are unable to confirm the diagnosis, you should then seek medical officer advice about further investigation.
