J10.01 — Influenza due to other identified influenza virus with the same other identified influenza virus pneumonia
Is J10.01 billable?
Yes — J10.01 is billable for FY2027. J10.01 is a valid, billable ICD-10-CM code at the highest level of specificity in its branch. J10.01 may be submitted for encounters from October 1, 2026 through September 30, 2027.

Which MS-DRGs does J10.01 group to?
J10.01 sits in MDC 04 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 177Respiratory Infections and Inflammations with MCCmedical
- 178Respiratory Infections and Inflammations with CCmedical
- 179Respiratory Infections and Inflammations without CC/MCCmedical
As a secondary diagnosis, J10.01 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
How is J10.01 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to J10.01. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Influenza › due to › identified influenza virus NEC › with › pneumonia › with same identified influenza virus (bronchial) (epidemic) (respiratory (upper)) (unidentified influenza virus)
Excludes1 — never code together — inherited from J10
The conditions below can never be reported together with J10.01 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 10
Report an additional code alongside J10.01 to fully describe the condition. J10.01 is sequenced first.
Use additional code — inherited from J09-J18
Report an additional code alongside J10.01 to fully describe the condition. J10.01 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 J10.01, but a patient may have both at the same time. When documentation supports it, J10.01 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 J10.01, but a patient may have both at the same time. When documentation supports it, J10.01 and the excluded code may both be reported.
Code also — inherited from J10.0
Two codes may be needed to describe the condition fully. Whether J10.01 is sequenced first depends on the reason for the encounter.
- associated lung abscess, if applicable (J85.1)
How long has J10.01 existed?
J10.01 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.
