High-value care

Services of proven efficacy reflecting current best medical practice, or for which the potential benefit to consumers exceeds the risk and costs.

Inappropriate use / misuse

The use of MBS services for purposes other than those intended. This includes a range of behaviours, from failing to adhere to particular item descriptors or rules through to deliberate fraud.

Low-value care

The use of an intervention that evidence suggests confers little benefit or no benefit to patients; or where the risk of harm from the intervention exceeds the likely benefit; or, more broadly, where the added costs of the intervention do not provide proportional added benefits.

Multiple operation rule

A rule governing the amount of Medicare benefit payable for multiple operations performed on a patient on the one occasion. In general, the fees for two or more operations are calculated by the following rule:
– 100 per cent for the item with the greatest schedule fee.
– Plus 50 per cent for the item with the next greatest schedule fee.
– Plus 25 per cent for each other item.

Multiple services rules

A set of rules governing the amount of Medicare benefit payable for multiple services provided to a patient at the same attendance (same day).

New service

Describes when a new service has been recommended, with a new item number. In most circumstances, these will need to go through MSAC. It is worth noting that the implementation of the recommendation may result in more or fewer item numbers than specifically stated.

No change or unchanged

Describes when the services provided under these items will not be changed or affected by the recommendations. This does not rule out small changes in item descriptors (e.g., references to other items, which may have changed as a result of the MBS Review or prior reviews).

Obsolete services/ items

Services that should no longer be performed as they do not represent current clinical best practice and have been superseded by superior tests or procedures.
