X2 – Influenza Due to Identified Novel Influenza A Virus with Other Respiratory Manifestations.
Influenza due to identified novel influenza A virus with other respiratory manifestations. J09. X2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Influenza due to unidentified influenza virus with other respiratory manifestations. J11. 1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
A novel influenza virus is an influenza A virus with a subtype that is different from the flu viruses that usually spread in people (H3N2 and H1N1). Some examples include H7N9, and H5N1. Occasionally, strains of influenza that normally affect birds, pigs, and other animals can infect humans.
The novel Influenza A (H1N1) is a respiratory disease caused by type A influenza viruses that cause regular outbreaks in pigs. People do not normally get H1N1, but human infections can and do happen.

The CPT® code modifier 59 is used to identify a distinct procedural service. In the context of influenza immunoassay testing, it supports coding CPT® 87400 once for influenza type A and once for influenza type B.

Similarly, an “A(H5N1)” virus has an HA 5 protein and an NA 1 protein. All known subtypes of influenza A viruses can infect birds, except subtypes A(H17N10) and A(H18N11), which have only been found in bats. Only two influenza A virus subtypes A(H1N1)pdm09, and A(H3N2), are currently circulating among people.
The 2009 H1N1 and H5N1 influenza viruses are newly (re-) emerged influenza A viruses (2009 A(H1N1) and A(H5N1), respectively) that have recently posed tremendous health threats in many regions worldwide. With the 2009 outbreak of H1N1 influenza A, the world witnessed the first influenza pandemic of the 21st century.
Where do pandemic influenza viruses come from? Different animals—including birds and pigs—are hosts to influenza A viruses that do not normally infect people.
