What it covers
The Ministry lists 786 as 'Signs and Symptoms Not Yet Diagnosed: Epistaxis, hemoptysis, cough, dyspnea, masses, shortness of breath, hyperventilation, sleep apnea', in the Diseases of the Respiratory System chapter.
Sleep apnea has no code of its own in the list, so 786 is where the Ministry puts it. The code also covers nosebleeds and coughing up blood.
