What are the steps an inmate must go through if they are seriously ill?

Inmates have the right to receive health care while in custody of the Federal Bureau of Prisons or any other penal system in the United States. Urgent and emergency medical care is available on-site 24-hours a day and seven days a week. Inmate must contact their unit officer or detail supervisor if they feel emergency care is necessary. All emergencies or injuries will be given priority for treatment. Appropriate medical care will be provided by institution hospital staff. Medical coverage on evenings, weekends, and holidays is for the treatment of acute medical problems only.
