According to what I can find about Origen, he was never made a bishop. He was ordained a priest in 230 A.D, against the wishes of the Bishop of Alexandria. His main base of operations was Caesarea, which is currently a coastal city in Israel.
Origen was not ordained as a priest, and certainly not as a bishop, by the Roman Church. However, he preached, wrote, taught, which lead to considerable conflict. None of this affected Origen's work. However, the folks in charge of the Roman Church experienced considerable stress and anxiety over all this, as Origen took on the important issues and established a code of theology, whilst others sat on the sidelines exercising their authority, with great pomp.

Whether one calls him a Bishop or not is really not the issue, in the usage of the term, he was a bishop, but in the then established church, he was a hanger on.

John Wesley suffered through similar issues with the English Church when he was establishing the Methodist movement.
He was ordained as a priest. It later got revoked.

He was never a Bishop as far as I can remember, nor find.
