In an application currently in production, one module of code is being modified. Is it necessary to re- test the whole application or is it enough to just test functionality associated with that module?

Hi
It depends on the modules effect by the change of the code and adding the code.
You first of all needs to identify the cause of the bug identified based on which need to identify all the areas can be effected with the fix of that and cover all the areas while testing.
Some times a small change may not require to test entire application and sometimes the small change can effect the entire application.

First of all using Requirement Traceability Matrix find impact of the modification of code in testcases then update the identified testcases which have impact and excute it after testcases are reviewed by Subject Matter expects

If one module of code is being modified in an application I think only modules associated with the module being modified should be retested.
Regression testing could be very cubersome in large applications or projects. in view of this i would say regression test should be carried out on only those modules associated with the modified module.
