Other rare lung diseases that develop in children, characterized by inflammation or scarring of the lung tissue affecting breathing.
Coding Tips
- •This is a catch-all code for childhood interstitial lung diseases not elsewhere classified; use only when specific diagnosis cannot be coded
- •Document the specific type of childhood interstitial lung disease when possible for better specificity
Clinical Significance
Other interstitial lung diseases of childhood is a catch-all code for pediatric ILDs that do not fit into more specific categories. This includes conditions like childhood-onset sarcoidosis ILD, rare genetic ILDs without specific codes, and other pediatric interstitial processes. Using this code indicates a complex pediatric respiratory condition requiring specialist management and monitoring.
Documentation Requirements
- ✓Documentation that the patient is a child with an interstitial lung disease not elsewhere classified
- ✓Imaging findings (chest CT) showing interstitial lung disease pattern
- ✓Biopsy results if performed, describing the specific pathologic pattern
- ✓Documentation that more specific childhood ILD codes (J84.841-J84.843) have been considered and do not apply
- ✓Clinical description of the specific childhood ILD type for medical record clarity
Commonly Confused Codes
J84.841 — Neuroendocrine cell hyperplasia of infancy should be used preferentially when NEHI is diagnosedJ84.842 — Pulmonary interstitial glycogenosis should be used when PIG is confirmedJ84.843 — Alveolar capillary dysplasia with vein misalignment should be used when ACD/MPV is confirmedJ84.89 — Other specified interstitial pulmonary diseases is for adults and should not be used for childhood ILDs
