Is J98 a billable ICD-10-CM code?

No. J98 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does J98 sit in the tabular list?

Diseases of the respiratory system (J00-J99), in the block Other diseases of the respiratory system (J96-J99).

What cannot be coded together with J98?

J98 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

J98 — Other respiratory disorders

Non-billable headerICD-10-CM

J98 is a non-billable header ICD-10-CM code for other respiratory disorders. 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.

newborn apnea (P28.4-)
newborn sleep apnea (P28.3-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

apnea NOS (R06.81)
sleep apnea (G47.3-)

Use additional code

Add a secondary code to capture the detail described below.

code 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)

Other codes that can never be billed with J98

These codes carry an Excludes1 note pointing at J98. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J98 alone.

Q33.0Congenital cystic lung
J43Emphysema
J84Other interstitial pulmonary diseases

Risk adjustment

J98 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 J98

9 child codes. Green means billable.
