The term "co-morbidities" is being used differently by the CDC than by the JAMA article.  The JAMA article (and, I'm guessing what Teejers is interested in) really discusses risk factors (chronic diseases present before the infection with COVID-19 that predisposes for a worse COVID-19 outcome).  The CDC really is looking through the discharge diagnosing and listing all concomitant conditions.  For example, sepsis is an acute event that would occur after developing COVID-19, not as a predisposing factor for COVID-19.  Although it is not directly caused by COVID, once someone is very sick, the body is susceptible to infection (made worse by being in a hospital and having all sorts of interventions like indwelling urinary catheters, IV lines, and endotracheal [breathing] tubes).  So, a patient who comes into the hospital with severe COVID-19 pneumonia, might develop a secondary infection which leads to sepsis, and can contribute to the patient's death.  Cardiac arrest is basically the final common pathway to death, almost regardless of cause (save for brain death).  At some point, the body's heart just can't support pumping blood through the body and either fails to generate a blood pressure (pulseless electrical activity, or PEA) or goes into a disorganized rhythm (ventricular tachycardia or ventricular fibrillation).  But "cardiac arrest" is obviously not a risk factor for COVID-19 pneumonia.
