J09.X — Influenza due to identified novel influenza A virus

Not billable

Is J09.X billable?

No — J09.X is a non-billable header code. J09.X groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath J09.X.

Inclusion terms

Alternative wording in documentation that is classified to J09.X.

  • Avian influenza
  • Bird influenza
  • Influenza A/H5N1
  • Influenza of other animal origin, not bird or swine
  • Swine influenza virus (viruses that normally cause infections in pigs)

Excludes1 — never code together — inherited from J09

The conditions below can never be reported together with J09.X on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • influenza A/H1N1 (J10.-)
  • influenza due to other identified influenza virus (J10.-)
  • influenza due to unidentified influenza virus (J11.-)
  • seasonal influenza due to other identified influenza virus (J10.-)
  • seasonal influenza due to unidentified influenza virus (J11.-)

Use additional code — inherited from Chapter 10

Report an additional code alongside J09.X to fully describe the condition. J09.X is sequenced first.

  • code, where applicable, to identify:
  • exposure to environmental tobacco smoke (Z77.22)
  • exposure to tobacco smoke in the perinatal period (P96.81)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Use additional code — inherited from J09-J18

Report an additional code alongside J09.X to fully describe the condition. J09.X is sequenced first.

  • code, if applicable, to identify resistance to antimicrobial drugs (Z16.-)

Excludes2 — not included here — inherited from Chapter 10

The conditions below are not part of J09.X, but a patient may have both at the same time. When documentation supports it, J09.X and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • smoke inhalation (T59.81-)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Excludes2 — not included here — inherited from J09-J18

The conditions below are not part of J09.X, but a patient may have both at the same time. When documentation supports it, J09.X and the excluded code may both be reported.

  • allergic or eosinophilic pneumonia (J82)
  • aspiration pneumonia NOS (J69.0)
  • meconium pneumonia (P24.01)
  • neonatal aspiration pneumonia (P24.-)
  • pneumonia due to solids and liquids (J69.-)
  • congenital pneumonia (P23.9)
  • lipid pneumonia (J69.1)
  • rheumatic pneumonia (I00)
  • ventilator associated pneumonia (J95.851)

What codes fall under J09.X? (4)

How long has J09.X existed?

J09.X has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
