J95.4 is the authoritative medical code for Chemical pneumonitis due to anesthesia. This classification is used in medical billing and clinical recording to specify the clinical criteria for chemical pneumonitis due to anesthesia (ICD-10-CM J95.4), 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
Chemical pneumonitis due to anesthesia is a billable ICD-10-CM diagnosis code J95.4. Inclusion terms: Mendelson's syndrome; Postprocedural aspiration pneumonia. Excludes1 (not coded here): aspiration pneumonitis due to anesthesia complicating labor and delivery O74.0; aspiration pneumonitis due to anesthesia complicating pregnancy O29; aspiration pneumonitis due to anesthesia complicating the puerperium O89.01. Excludes2 (not included here): aspiration pneumonia J69.-; emphysema subcutaneous resulting from a procedure T81.82; hypostatic pneumonia J18.2; pulmonary manifestations due to radiation J70.0-J70.1.
