Artie Lange said on Thursday that he had been fired from his recurring role on the HBO series “Crashing.” But HBO and Judd Apatow, one of the show’s executive producers, said that he had not been let go.

Mr. Lange, who has waged a public battle against heroin addiction, was arrested this month on charges of possession of drugs, including cocaine and heroin. A story line in the series depicts Pete Holmes, the show’s creator who also plays a version of himself, trying to keep Mr. Lange’s character from relapsing.

In an interview with the radio station WOR, Mr. Lange told the hosts, Len Berman and Todd Schnitt, that he had been let go. When asked why, Mr. Lange said, “What have we been talking about? I might go to jail.”

Later in the interview, he said, “It was the one time that critics actually liked what I did.”

When a host complimented his performance, Mr. Lange responded, “Well, it’s the last time you’ll see it.”
