Wrong Program was associated during claim and settled, Options to correct?

Summary:

The wrong program was chosen for association during claim processing and is settled. For example, a volume program was associated in the claim instead the lump sum program. What options are available to correct?

Currently considering options of manually overriding the journal entries. Also considering using Manual adjustments to "true up" the balances of each program, however, manual adjustments are not supported for Volume programs, so how can these be corrected in this example?
