                           Title II disability beneficiaries have the option to return to work by ensuring work
                              activity alone will not trigger a medical CDR.

                        b.  
                           Beneficiaries who are entitled to Title II, or concurrently entitled to both Title
                              II and Title XVI benefits for at least 24 months will not be subject to a medical

When a Title II beneficiary completes a TWP, it is necessary to investigate all work
                  (including work performed during the TWP) to determine whether the work activity indicates
                  the ability to perform substantial gainful activity and result in a continuance or
                  cessation.
