T53.7 is the authoritative medical code for Toxic effects of other halogen derivatives of aromatic hydrocarbons. This classification is used in medical billing and clinical recording to specify the clinical criteria for toxic effects of other halogen derivatives of aromatic hydrocarbons (ICD-10-CM T53.7), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Toxic effects of other halogen derivatives of aromatic hydrocarbons is a non-billable ICD-10-CM category code T53.7. A more specific billable subcode must be selected for claims submission. Excludes1 (not coded here): contact with and suspected exposure to toxic substances Z77.-. Use additional code: code(s):; for all associated manifestations of toxic effect, such as: respiratory conditions due to external agents J60-J70; personal history of foreign body fully removed Z87.821; to identify any retained foreign body, if applicable Z18.-. 7th character: The appropriate 7th character is to be added to each code from category T53.
