Influenza due to unidentified influenza virus with other respiratory manifestations

Billable Code

| ICD-10 from 2011 - 2016

J11.1 is a billable ICD code used to specify a diagnosis of influenza due to unidentified influenza virus with other respiratory manifestations. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code J11 is used to code Influenza

Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus. Symptoms can be mild to severe. The most common symptoms include: a high fever, runny nose, sore throat, muscle pains, headache, coughing, and feeling tired. These symptoms typically begin two days after exposure to the virus and most last less than a week. The cough, however, may last for more than two weeks. In children, there may be nausea and vomiting, but these are not common in adults. Nausea and vomiting occur more commonly in the unrelated infection gastroenteritis, which is sometimes inaccurately referred to as "stomach flu" or "24-hour flu". Complications of influenza may include viral pneumonia, secondary bacterial pneumonia, sinus infections, and worsening of previous health problems such as asthma or heart failure.
