J15 — Bacterial pneumonia, not elsewhere classified
Is J15 billable?
No — J15 is a non-billable header code. J15 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 14 billable codes beneath J15.

Excludes1 — never code together
The conditions below can never be reported together with J15 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before J15. J15 describes a manifestation and cannot be the principal or first-listed diagnosis.
Code also
Two codes may be needed to describe the condition fully. Whether J15 is sequenced first depends on the reason for the encounter.
Includes
Conditions classified to J15.
- bronchopneumonia due to bacteria other than S. pneumoniae and H. influenzae
Use additional code — inherited from Chapter 10
Report an additional code alongside J15 to fully describe the condition. J15 is sequenced first.
Use additional code — inherited from J09-J18
Report an additional code alongside J15 to fully describe the condition. J15 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 J15, but a patient may have both at the same time. When documentation supports it, J15 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 J15, but a patient may have both at the same time. When documentation supports it, J15 and the excluded code may both be reported.

How long has J15 existed?
J15 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.
Which codes are confused with J15?
ICD-10-CM declares these codes mutually exclusive with J15 — exactly one of each pair can be correct for a given encounter.
