T58.2X2 is the authoritative medical code for Toxic effect of carbon monoxide from incomplete combustion of other domestic fuels, intentional self-harm. This classification is used in medical billing and clinical recording to specify the clinical criteria for toxic effect of carbon monoxide from incomplete combustion of other domestic fuels, intentional self-harm (ICD-10-CM T58.2X2), 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 effect of carbon monoxide from incomplete combustion of other domestic fuels, intentional self-harm is a non-billable ICD-10-CM category code T58.2X2. A more specific billable subcode must be selected for claims submission. Includes: asphyxiation from carbon monoxide; toxic effect of carbon monoxide from all sources. 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 T58.
