What Is Medicare Part T? 
There is no part of Medicare titled Part T. Medicare consists of 4 main parts - A , B , C , and D . There are also 10 Medigap plans -LRB- a.k.a. Medicare supplement plans -RRB- - A , B , C , D , F , G , K , L , M , and N. Are you perhaps referring to your Medicare claim number ? Your claim number is your social security number plus a letter . The letter T is one of the common ending characters to a claim number . If you have a claim number ending in `` T '' , it designates that you are either uninsured , but entitled to Part A or are fully insured and have elected to only take Part A. I hope that answers your question . Please let me know if I can be of further assistance . Thanks very much .
