An insulin pump is configurable by a configurator. The pump has parameter blocks, each with a respective parameter and an associated restriction setting, and the configurator has an authorization level. Configuring the pump includes receiving, by the configurator, a request to access a parameter on the pump. The method also includes identifying, by the configurator, the parameter block that includes the parameter. Moreover, the method includes retrieving, by the configurator from the pump, the parameter and the associated restriction setting, and comparing, by the configurator, the authorization level of the configurator to the restriction setting. Also, the method includes determining, by the configurator, whether the configurator is authorized to write to the parameter block based on the comparison. Additionally, the method includes writing, by the configurator, to the parameter block on the insulin pump in response to a determination that the configurator is authorized to write to the parameter block.
