Current RMA Instruments:
|Reasonable Hypothesis SOP||98 of 2014|
|Balance of Probabilities SOP||99 of 2014|
Changes from Previous Instruments:
- 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
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
If, after applying the above information, you are unable to confirm the diagnosis, you should then seek medical officer advice about further investigation.
