Dr. Mark M Chung has the following 2 specialties

  • Internal Medicine

    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
    In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

  • Pulmonary Disease

    A pulmonologist is a physician who specializes in the diagnosis and treatment of conditions related to the lungs and respiratory tract.
    These specialists are similar to critical care specialists in that their patients often require mechanical ventilation to assist their breathing.
    Pulmonologists diagnose and treat patients with conditions such as asthma, cystic fibrosis, asbestosis, pulmonary fibrosis, lung cancer, COPD, and emphysema. Exposure and inhalation of certain toxic substances may also warrant the services of a pulmonologist.
    Some of the tools and tests pulmonologists use to diagnose a patient are a stethoscope in order to listen for abnormal breathing sounds, chest X-rays, CT scans, blood tests, bronchoscopy, and polysomnography.

Total Dissatisfaction with Chung and his staff

Chung and his staff is only concerned about Health insurance payments and providing guidance or information about coordination of coverages with other providers who he did not respond to their requests for information even though he used their mouth pieces for sleep disorder tests and follow up. In the end after numerous calls to his office for assistance, he even threatened harassment. Clearly, not a professional response to aid patient he provided services.

Sign away your rights

Until you enter the office for the first time you will not know that Dr. Chung will not even see you unless you sign away your rights or privileges to privacy, litigation, phone prescription refills, etc. I wasn't allowed to see the doctor by the office staff. I've never litigated or even complained about a doctor before but this is too much - I went to another specialist.
