2025 ICD-10-CM code J10.8
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Infectious Diseases - Influenza and pneumonia Chapter 10: Diseases of the respiratory system Feed
Influenza due to other identified influenza virus with other manifestations.
Modifiers may be applicable depending on the circumstances and services performed; consult the CMS guidelines for appropriate modifier use.
Medical necessity for this code is established when a patient presents with symptoms consistent with influenza and testing confirms the presence of an identified influenza virus; the presence of additional manifestations beyond the usual flu symptoms supports the diagnosis.
Diagnosis and management of influenza infection, including assessment of symptoms, ordering of diagnostic tests (if necessary), and treatment of symptoms and complications.
In simple words: This code is for the flu caused by a known flu virus (not a new kind), but with extra symptoms beyond the usual aches, fever, and cough.
This ICD-10-CM code classifies influenza caused by identified influenza viruses (excluding avian, swine, and unidentified influenza viruses)that presents with manifestations beyond the typical symptoms.These additional manifestations are not specified but could include various complications such as myocarditis, otitis media, or encephalopathy.The code is used when a specific influenza virus is identified (A, B, or C, but not novel strains), and additional symptoms beyond those typically associated with influenza are present.
Example 1: A 35-year-old presents with fever, cough, myalgia, and also exhibits signs of acute bronchitis.Influenza A is confirmed via rapid antigen test.J10.8 is coded along with a code for acute bronchitis. , A 60-year-old with a history of heart failure presents to the ED with symptoms of influenza and develops new onset atrial fibrillation. Influenza B is confirmed.J10.8 is coded, along with codes for the atrial fibrillation and heart failure., A 22-year-old college student has a fever, cough, and headache, later developing an ear infection (otitis media).The influenza A virus is identified.J10.8 is coded with an additional code for otitis media.
Complete history and physical examination, documentation of influenza symptoms, positive test results confirming influenza virus (e.g., rapid antigen test, PCR), documentation of any additional manifestations (e.g., chest x-ray for pneumonia, EKG for myocarditis), and notes about treatment provided.
** This code is for influenza caused by identified influenza viruses, excluding novel strains.Always document the specific virus identified and all clinical findings for accurate coding.
