J84.89

J84.89 — Other specified interstitial pulmonary diseases

Billable / specific codeICD-10-CM

J84.89 is a billable, specific ICD-10-CM code for other specified interstitial pulmonary diseases. It is valid for submission on a claim.

Excludes1 — never code together

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

cryptogenic organizing pneumonia (J84.116)
idiopathic non-specific interstitial pneumonitis (J84.113)
lipoid pneumonia, exogenous or unspecified (J69.1)
lymphoid interstitial pneumonia (J84.2)

Code first

The underlying condition must be sequenced before this code.

, if applicable:
poisoning due to drug or toxin (T51-T65 with fifth or sixth character to indicate intent), for toxic pneumonopathy
underlying cause of pneumonopathy, if known

Use additional code

Add a secondary code to capture the detail described below.

code, for adverse effect, to identify drug (T36-T50 with fifth or sixth character 5), if drug-induced

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Endogenous lipoid pneumonia
Interstitial pneumonitis
Non-specific interstitial pneumonitis NOS
Organizing pneumonia NOS

Other codes that can never be billed with J84.89

These codes carry an Excludes1 note pointing at J84.89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J84.89 alone.

J69.1Pneumonitis due to inhalation of oils and essences
J84.113Idiopathic non-specific interstitial pneumonitis
J84.116Cryptogenic organizing pneumonia

Risk adjustment

J84.89 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:

HCC 280 Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders0.319 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.

Medicare coverage

J84.89 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
