Conrad Murray, the doctor of the late Michael Jackson, has returned to work.
After pleaded not guilty to charges of the 'unlawful killing' of the singer, Dr Murray was released on bail.
At a court in Los Angeles the doctor denied counts of manslaughter and was given bail for $75,000 (£48,000).
If convicted he faces up to four years in prison. He is due back in court in April.
Dr Murray's lawyer, Edward Chernoff, has stressed the 56-year-old's intention "to keep practising medicine".
A spokeswoman for Dr Murray and Chernoff, Miranda Sevcik, said the doctor had own premises in the city in August 2009 and was making arrangements to work out of another physician's office in Las Vegas.
Sevcik said: "We're not sharing the location because the doctor's primary concern is for his patients' privacy."
Under the terms of his release, Murray is permitted to practise medicine but is restricted from using certain types of medication.
At the hearing, Judge Keith Schwartz told cardiologist Murray: "You may not under any circumstances use any anaesthetic agents, specifically Propofol."
Michael Jackson died aged 50 at his home in June last year. A full autopsy report, released this week, showed that Michael Jackson died from acute intoxication.
In the 51-page document, it stated that toxicology studies had shown "a high blood concentration of Propofol as well as the presence of benzodiazepines."
It read:"The autopsy did not show any trauma or natural diseases which would cause death."
The report concluded that the cause of death was "acute propofol intoxication" and that the benzodiazepine was a "contributory factor in the death".
Dr Conrad Murray stands accused of involuntary manslaughter.
The report continued: "The manner of death is homicide, based on the following: circumstances indicate that Propofol and benzodiazepines were administered by another. The Propofol was administered in a non hospital setting without any appropriate medical indication.
"The standard of care for administrating Propofol was not met. Recommended equipment for patient monitoring, precision dosing and resuscitation was not present. The circumstances do not support self administration of Propofol."
Murray, who has always maintained he neither prescribed nor administered anything that should have killed the singer, denies the charges .
A hearing has been set for April 5 in Los Angeles.
