J84.89 is the authoritative medical code for Other specified interstitial pulmonary diseases. This classification is used in medical billing and clinical recording to specify the clinical criteria for other specified interstitial pulmonary diseases (ICD-10-CM J84.89), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Official Registry Overview & Definition
Other specified interstitial pulmonary diseases is a billable ICD-10-CM diagnosis code J84.89. Inclusion terms: Endogenous lipoid pneumonia; Interstitial pneumonitis; Non-specific interstitial pneumonitis NOS; Organizing pneumonia NOS. Excludes1 (not coded here): cryptogenic organizing pneumonia J84.116; idiopathic non-specific interstitial pneumonitis J84.113; lipoid pneumonia, exogenous or unspecified J69.1; lymphoid interstitial pneumonia J84.2; exogenous lipoid pneumonia J69.1; unspecified lipoid pneumonia J69.1; drug-induced interstitial lung disorders J70.2-J70.4; interstitial emphysema J98.2. Excludes2 (not included here): lung diseases due to external agents J60-J70. Code first: , 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: code, for adverse effect, to identify drug (T36-T50 with fifth or sixth character 5), if drug-induced. Code also: , if applicable, associated condition.
