Understanding multiple service rules

The Multiple Service Rules (MSR) engine calculates Medicare and Health Fund fee adjustments when an invoice contains items that trigger service rules. This includes diagnostic imaging rules and operation rules. HealthTrack applies these automatically during invoicing.

The MSR is a property that can be turned on or off in your HealthTrack system. If the Apply Rules button does not appear on your invoicing screen, call HealthTrack and they will assist you in setting up this feature.

How Multiple Service Rules Work

As you add items to an invoice, HealthTrack checks whether any Medicare or Health Fund rules apply to the combination of items. When rules are detected, the Apply Rules button on the invoice screen turns yellow.

You do not need to calculate the adjustments yourself. HealthTrack handles the rule logic and presents the adjusted fees for your review.

Review and Accept Rule Changes

Add all billing items to the invoice as normal.
When the Apply Rules button turns yellow, click it to open the rules screen.

You can also skip clicking Apply Rules and go straight to Issue or Save & Pay. The rules screen appears automatically before the invoice is finalised.

The Invoice Rules – Confirm Rule Changes screen opens. Review the adjustments:
