The physician implicated in Matthew Perry's ketamine overdose case remains free on bond and is unable to practice medicine.

Matthew Perry was conspired to receive surgical anesthetic ketamine by Dr. Mark Chavez, who was granted freedom on bond.

On Friday, Chavez appeared in Los Angeles court after agreeing to a plea deal earlier this month. U.S. Magistrate Judge Jean P. Rosenbluth informed him that he could remain free on bond with certain conditions, including surrendering his passport and refraining from working as a doctor.

Chavez did not enter his guilty plea or speak about the case, which he will do with another judge at a later date.

If Chavez pleads guilty, he could face a maximum of 10 years in prison.

Dr. Mark Chavez's attorney, Matthew Binninger, stated that Chavez is deeply sorry for the incident and is taking all necessary steps to rectify the wrongdoing.

Binninger stated that his client did not take responsibility today because it was not on the calendar, but he intends to do so at a change of plea hearing in the near future.

According to an autopsy completed on Oct. 29, the acute effects of ketamine were the cause of death for Perry on Oct. 28. Drowning, coronary artery disease, and buprenorphine effects were also listed as contributing factors.

Dr. Chavez pleaded guilty to one count of conspiracy to distribute ketamine as part of his plea agreement. He admitted to selling ketamine to Dr. Plasencia, including ketamine that he had diverted from his former clinic.

Previously, Chavez ran a ketamine clinic and is accused of submitting a false prescription for the drug in the name of a former patient to obtain it. Additionally, Plasencia is alleged to have taught Perry's assistant how to administer the drug to the actor.

According to court documents obtained by Planet Chronicle Digital, Perry had been seeking a new ketamine source a month before his death after his doctor refused to provide him with more of the drug.

Perry came across Plasencia, who reached out to Chavez for the ketamine.

"I'm curious about how much this idiot will pay," Plasencia texted Chavez, court documents revealed. "Let's discover."

Plasencia pleaded not guilty and is awaiting trial.

Three others were charged in connection to Perry's death.

Kenneth Iwamasa, Perry's assistant, pleaded guilty on Aug. 7 to one count of conspiracy to distribute ketamine, causing death. Iwamasa admitted to repeatedly injecting Perry with ketamine without medical training, including performing multiple injections on the day Perry died.

Jasveen Sangha, known as "The Ketamine Queen," was indicted on six charges related to drug distribution, including one count of conspiracy to distribute ketamine, one count of maintaining a drug-involved premises, one count of possession with intent to distribute methamphetamine, one count of possession with intent to distribute ketamine, and five counts of ketamine distribution.

On Aug. 8, Erik Fleming pleaded guilty to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death. Fleming admitted in court documents that he distributed the ketamine that killed Perry.

According to court documents, Perry was killed on Oct. 28 by ketamine allegedly provided by Sangha and delivered to Iwamasa by Fleming.

At 8:30 a.m., Perry's assistant administered a shot of ketamine to the actor. By 12:45 p.m., Perry instructed Iwamasa to give him another injection while watching a movie. About 40 minutes later, Perry allegedly requested another injection, saying, "Shoot me up with a big one," according to the plea agreement.

While Perry was in a Jacuzzi, the live-in assistant administered a third injection. After leaving the home to run errands, Iwamasa returned to find Perry "face down" in the Jacuzzi, deceased.

Authorities alleged that the three of them collaborated to conceal their role in Perry's demise.
