Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to J10.1: its own notes plus those printed at J10, block J09-J18, and Chapter 10. A note printed at a category, block or chapter applies to every code under it.

Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may 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)
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code, if applicable, to identify resistance to antimicrobial drugs (Z16.-)
Notes
General instructions on how these codes are used.
- When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

Patient EducationClinical
Flu
The flu, also called influenza, is a respiratory infection caused by viruses. Each year, millions of Americans get sick with the flu. Sometimes it causes mild illness. But it can also be serious or even deadly, especially for people over 65, newborn babies, and people with certain chronic illnesses.

Questions About J10.1Overview
Is J10.1 (Influenza due to other identified influenza virus) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report influenza due to other identified influenza virus with other respiratory manifestations on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J10.1 group to?
When influenza due to other identified influenza virus with other respiratory manifestations is the principal diagnosis on an inpatient stay, it groups to MS-DRG 195, 793, 791, 193, 194, with relative weights from 0.6062 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Can J10.1 be reported with a code from J09.X?
Not as a rule. The Excludes1 note at J10, which applies to J10.1, lists "influenza due to avian influenza virus (J09.X-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
Does J10.1 need an additional code?
When the condition applies, yes. The Use Additional Code note reads: code for associated pleural effusion, if applicable (J91.8); code for associated sinusitis, if applicable (J01.-). The additional code is reported after J10.1.
What is the ICD-9 equivalent of J10.1?
Under the General Equivalence Mappings, influenza due to other identified influenza virus with other respiratory manifestations converts to ICD-9-CM 487.1 (flu w resp manifest NEC) and 488.12 (Flu-2009 H1N1 w oth resp). The mapping is approximate, so confirm the match fits the documentation.
