His bond was set at $200,000.
The Monroe County sheriff’s office reportedly, have been under investigation Dr Tamayo and his business since November 2016, as well as,  and other state and federal agencies.
A key staffer who worked under Tamayo’s supervision, Amarylis Maristan, 47, is wanted on the same charges.
According to authorities, Tamayo and Maristan operated two unlicensed elder living facilities in Plantation Key from April 2016 until October 2016. A second establishment operated in Kay Largo from October 2016 until December 2016 .
Tamayo and Maristan, the sheriff’s department said,  were caring for six women in the Keys who were older than 80.
All the patients had chronic and acute medical conditions that required medical care and multiple prescription medications.
The doctor allegedly, failed to provide care for the patients at the facilities, then falsified records to indicate that he was providing care.In addition, authorities said, the doctor knew the facilities were unlicensed and knew that Maristan who supervised the facilities was not medically trained in any way.
Tamayo was also paid by Medicare for services he was not providing, authorities said. Herrin said the investigation into Medicare fraud is continuing.
Maristan, now on the run,  is also accused of knowingly operating an unlicensed facility and not providing appropriate and necessary medical treatment to the patients under her care.

Monroe County sheriffs detective and an investigator from the Florida Department of Children and Families kicked off the investigation after receiving a report of possible elder
DCF was contacted by the Hospital after an 85-year-old woman was brought in with cardiac arrest,  covered in urine with severe bedsores, some of them infected, sheriff’s office spokesperson, Becky Herrin said.
In the dementia care facility, all the patients were confined to beds or wheelchairs, were diagnosed with memory loss or dementia and were incontinent, Herrin said.
Investigators found that a majority of the women had UTIs [urinary tract infections] and bedsores.
The patient who sparked the investigation, died the next day. . Medical records show that at the time of the woman’s death, she was underweight, suffered from malnutrition and had been suffering from seizures. An autopsy showed that she died of “complications of septic shock due to pneumonia,” Herrin said
Detectives said Tamayo was aware of her history of seizures and had billed the government for seizure medication that was never given to the victim.
Maristan, who was the woman’s caregiver, was interviewed by detectives at the Key Largo facility, where Maristan also lived. Herrin said she told them that Tamayo made house calls to the home, where he had seen the patient and prescribed medication as needed to all the elderly people who lived there.
The remaining patients in the facility were sent to hospital for evaluation before being transferred to a licensed care facility.
Tamayo who graduated in 1977 from a medical school in Havana, Cuba, practices medicine from his office at The Medical Health Of Miami, clinic. He is listed as being non-Board Certified.
Authorities said the victim who died had not been treated for bedsores or for pneumonia, from which she ultimately died.
Detectives said Tamayo falsified medical records that claimed that he had seen the victim in person. Law enforcement investigators said Tamayo also failed to treat a second woman at the facility for pneumonia and Parkinson’s disease.
However, he did admit  that he was responsible for medical supervision at the two facilities as well as, knowing that Maristan was unlicensed and untrained.
Detectives are still searching for the now fugitive Maristan.
