If evidence already in a claim is insufficient to make a failure to follow prescribed
treatment (FTFPT) determination, you must develop the evidence until it is sufficient
to complete the FTFPT determination. You may contact the individual, the individual’s
medical source(s), and third parties using the procedures in this section.
Always document the content of your contact in the claim communication section of
eCAT. For paper cases, use an SSA-5002 (Report of Contact).
