•        Medical improvement expected - review will occur between 6 and 18 months after the final administrative decision.  This includes conditions from which recovery can be anticipated.  Example: a fracture that is expected to heal.

•        Medical improvement is possible; non permanent impairment - review every 3 years.  This includes impairments for which improvement cannot be predicted at the time of the decision, and conditions that are not expected to improve, but are not considered as severe as a permanent impairment.        Examples: regional enteritis, hyperthyroidism, chronic ulcerative colitis.    
  

•       Medical improvement not expected, permanent impairment - review will occur every 5 to 7 years. Includes extremely severe conditions that are considered permanent, or, because of the individual's age or lack of recent work experience would suggest less likelihood of recovery and return to the work force. Example: Parkinson's Syndrome, ALS, amputations.

• Advances in, or improvements of, medical or occupational therapy received by an individual or that could affect an illness.
• An individual returns to work and successfully completes a trial work period, or substantial earnings are reported on an individual's earning record.

• Someone in a position to know tells SSA that the individual is working, is not following prescribed treatment of an SSA provision, or is no longer disabled.
