Is J15 a billable ICD-10-CM code?

No. J15 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does J15 sit in the tabular list?

Diseases of the respiratory system (J00-J99), in the block Influenza and pneumonia (J09-J18).

What cannot be coded together with J15?

J15 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

J15

J15 — Bacterial pneumonia, not elsewhere classified

Non-billable headerICD-10-CM

J15 is a non-billable header ICD-10-CM code for bacterial pneumonia, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

chlamydial pneumonia (J16.0)
congenital pneumonia (P23.-)
Legionnaires' disease (A48.1)
spirochetal pneumonia (A69.8)

Code first

The underlying condition must be sequenced before this code.

, if applicable, associated influenza (J09.X1, J10.0-, J11.0-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

, if applicable, any associated condition such as:
abscess (J85.1)
aspiration pneumonia (J69.-)

Includes

Conditions this code covers.

bronchopneumonia due to bacteria other than S. pneumoniae and H. influenzae

Other codes that can never be billed with J15

These codes carry an Excludes1 note pointing at J15. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J15 alone.

J13Pneumonia due to Streptococcus pneumoniae
J15.4Pneumonia due to other streptococci
Z16Resistance to antimicrobial drugs

Risk adjustment

J15 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead J15

10 child codes. Green means billable.
