When Matthew Moore went for a normal checkup with a new doctor, he expected things to go normally. After he realized that his doctor had listed homosexuality as a “chronic condition” within his charts, he decided to sue.

Moore, 46, tried to laugh off the diagnosis that Dr. Elaine Jones gave him back in April of 2013. The diagnosis was put on both his patient plan and included in his health chart, along with other items such as high cholesterol, high blood pressure and a deficiency in the vitamin B-12. Its inclusion with these items, and throughout his medical records led him to believe that this diagnosis was no laughing matter.

“At first, I kind of laughed,” Moore said, “…and then as I thought about it and as I dealt with it, it angered me.”

Dr. Jones has defended the diagnosis by allegedly stating that it is still commonly debated within the medical industry as to whether or not homosexuality is a disease and claims that it is still often used as a diagnosis in clinical settings.

Homosexuality was included in the first version of the Diagnostic and Statistical Manual (DSM) as the personality disorder sociopathic personality disturbance, also known as Code 302.0. In 1980, the DSM III changed the diagnosis to ego-dystonic homosexuality. The original intent was to remove it due to overwhelming empirical evidence that stated homosexuality was not a pathological disorder, but the compromise of changing the name was reached after certain groups objected. In 1986, the evidence prevailed and the diagnosis was removed from the DSM entirely.

Since then, the medical field at large has not regarded homosexuality as a condition or disease or anything diagnosable. It appears that Dr. Jones missed that memo and as a result, Moore is suing her.

Moore says he intends to sue as a way to ensure that others might not have to endure the discrimination brought upon him.
