2025 ICD-10-CM code J84.89
(Active) Effective Date: N/A Diseases of the respiratory system - Other interstitial pulmonary diseases 10 Feed
Other specified interstitial pulmonary diseases. This includes conditions like endogenous lipoid pneumonia, interstitial pneumonitis, and non-specific interstitial pneumonitis NOS.
Medical necessity should be established by documenting the signs, symptoms, and diagnostic findings that support the diagnosis of interstitial lung disease. The documentation should also indicate the severity of the condition and its impact on the patient's respiratory function.
The clinician is responsible for diagnosing the specific interstitial lung disease and documenting the findings that support the diagnosis. This includes imaging studies, pulmonary function tests, and possibly lung biopsy.

In simple words: This code refers to other specific types of interstitial lung diseases.Interstitial lung diseases affect the tissue and space around the air sacs of the lungs.Some examples included in this code are endogenous lipoid pneumonia, interstitial pneumonitis, and organizing pneumonia.
This code represents other specified interstitial pulmonary diseases, including endogenous lipoid pneumonia, interstitial pneumonitis, non-specific interstitial pneumonitis NOS, and organizing pneumonia NOS. If applicable, code first any poisoning due to drug or toxin (T51-T65 with fifth or sixth character to indicate intent) for toxic pneumonopathy, or the underlying cause of pneumonopathy if known. Use an additional code for adverse effect to identify the drug (T36-T50 with fifth or sixth character 5) if drug-induced. Excludes1: cryptogenic organizing pneumonia (J84.116), idiopathic non-specific interstitial pneumonitis (J84.113), lipoid pneumonia (exogenous or unspecified) (J69.1), and lymphoid interstitial pneumonia (J84.2).
Example 1: A patient presents with shortness of breath and cough. Imaging reveals findings consistent with interstitial pneumonitis, but the cause is not identified. J84.89 is used., A patient with a history of rheumatoid arthritis develops interstitial lung disease. After extensive workup, the specific type of interstitial lung disease cannot be determined. J84.89 is used., A patient develops organizing pneumonia following a COVID-19 infection. J84.89 is used, along with the appropriate code for the post-COVID condition (e.g., U09.9).
Documentation should include the type of interstitial lung disease, clinical findings (symptoms, physical exam), results of diagnostic tests (imaging, pulmonary function tests, biopsy if performed), and any associated conditions.
** For post-COVID conditions, use the appropriate code in category U09. Ensure documentation clearly distinguishes this code from other, more specific interstitial lung diseases.
