Modifiers help to identify instances where the circumstances deviate from the norm.

Type of modifiers:

AM - Addition modifier - This indicates that when using this modifier the tariff will be increased.

IM - Information modifiers - These modifiers are for information only and don't have monetary value.

RM - Reduction Modifiers - In certain cases, the tariff is decreased due to the fact that eg. post-operative care runs concurrently for all the procedures performed.
