Bates, 26, from Leicester, England, would likely have represented GB at the Paralympic Games in Japan in 2021, but the International Paralympic Committee (IPC) ruled that his disability did not meet its eligibility categories.
He has represented GB at the World and European Championships, helping the GB team win gold and silver medals.
Bates was injured while playing football at the age of 11 and then developed Complex Regional Pain Syndrome (CRPS), which left him walking with the use of a crutch and left him in a constant pain.
Bates, who was discovered wheelchair basketball at the age of 13, learned on Tuesday that his disability did not meet his strict criteria for playing in international games - a decision he is appealing.
He said he is considering have your own leg amputated so you can compete and claimed on Twitter that he would take legal action against the body.
The IPC revised its classification criteria in 2015 to include only 10 eligible disability categories. At the time, the International Wheelchair Basketball Federation (IWBF) adhered to its own separate criteria - which included Bates' condition.
However, a spokeswoman for the IWBF told CNN that she now aligned her own rules with the CPI by following, she said, the pressure exerted by the body and did so "with great sadness ".
CNN has contacted the IPC for comment.
Speaking to the BBC's 'Today' show on Thursday, Bates said: "The IPC has forced the International Wheelchair Basketball Federation to change its classification code.
"They basically want every handicap ... to fit into a little 10 point category and if you are not in any of those points you are considered ineligible, even if they recognize that you have a handicap, which is. nice. of what happened in my case. "
Disability is not " black and white "
The IPC, he said, had recognized that he suffered from CRPS and had lasting effects on muscle power, weight bearing and range of motion, but nevertheless stated that the disability was not one of his criteria.
"I totally agree that there has to be a process to go through it, but like I said, I am unable to walk properly and have to walk with an aid. What more is needed than that? "he said.
"They recognized that I had a handicap, but it does not correspond to their 10 points [check list]. There are going to be hundreds of disabilities like that because disability is not a black and white thing, it is not a checkbox that you can make. "
He wondered how a person could be registered as a person with a disability, but unable to participate at the highest level of sport.
When asked if he was serious about having his leg amputated to meet the IPC criteria, he replied that if his remedies and other avenues are "exhausted" then "he will have to take into consideration ".
Ulf Mehrens, President of the IWBF, said in a statement to CNN: "I want to stress that a player who has been found ineligible has not cheated the system or intentionally twisted in anyway.
"The IWBF still fully believes in our classification philosophy and that sport should be inclusive for anyone with eligible lower limb disabilities ... However, as a member of the Paralympic movement and a signatory of the IPC Code, the IWBF must comply with the requirements of the IPC. "
