If there is an increase to the service amount, the provider can simply bill for the additional amount, using the same PA#.
If there is a reduction in services, first check with the provider to verify the actual units of service provided. Once you have verified this information, simply reduce the units in the current Service Plan to reflect the services provided. Please do not rely on the system to tell you if claims are submitted, as there is a 10 day lag in reporting. If the provider is no longer providing services, then you will change the end date for that provider.
If you need to create a service plan for a different provider, at this point you may do so. Simply enter the correct start date, and proceed as usual.
