Flu Like Symptoms ICD-10-CM Codes

What ICD-10 Codes are Used for Flu Like Symptoms? 

The term "flu-like symptoms" is broad, covering various conditions. Here are some typical Flu Like Symptoms ICD Codes:

J10.1

Used when a patient is diagnosed with influenza caused by a specific, identified influenza virus (other than novel influenza virus), and exhibits additional respiratory symptoms or complications beyond the typical flu-like symptoms. These respiratory manifestations may include bronchitis, pneumonia, or other respiratory disorders directly associated with the influenza virus.

J11.1

The main difference between the first one is that this code is used when the specific influenza virus causing the infection cannot be identified. The patient presents with flu-like symptoms and additional respiratory manifestations, but the virus responsible for the infection is not determined or is not tested for. 

J11.8

Similar to J11.1, this code is used when the specific influenza virus causing the infection cannot be identified. However, the patient may exhibit manifestations beyond just respiratory symptoms in this case. These additional manifestations could include non-respiratory symptoms such as gastrointestinal issues, neurological symptoms, or other systemic manifestations associated with the flu.

J10.2

This code is used when a patient is diagnosed with influenza caused by a specific, identified influenza virus (other than novel influenza virus), and experiences gastrointestinal symptoms or complications in addition to typical flu-like symptoms. Gastrointestinal manifestations may include symptoms like nausea, vomiting, diarrhea, or abdominal pain.

J11.2

Similar to J10.2, this code is used when the specific influenza virus causing the infection cannot be identified, but the patient presents with gastrointestinal symptoms in addition to flu-like symptoms. The gastrointestinal symptoms may be prominent and require medical attention and supportive flu care.

Which Flu Like Symptoms ICD codes are Billable?

J10.1, J11.1, J11.08, J10.2, and J11.2 are all billable/specific ICD-10-CM codes used for indicating diagnoses for reimbursement purposes.

• Annual vaccination is the best preventive measure against flu-like illnesses.
• If experiencing flu-like symptoms, it's important to stay home to avoid spreading the illness, drink plenty of fluids, rest, and take over-the-counter medications for relief.
• Seek medical attention if symptoms are severe or do not improve after a few days.
