Non-billable headerICD-10-CM

J84.11 is a non-billable header ICD-10-CM code for idiopathic interstitial pneumonia. 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.

lymphoid interstitial pneumonia (J84.2)
pneumocystis pneumonia (B59)

Other codes that can never be billed with J84.11

These codes carry an Excludes1 note pointing at J84.11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J84.11 alone.

J84.89Other specified interstitial pulmonary diseases
J98.4Other disorders of lung

Risk adjustment

J84.11 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 J84.11

7 child codes. Green means billable.
