2025 Adverse Effect ICD-10-CM Codes - Page 5
The 2025 Adverse Effect ICD-10-CM Codes list includes 2,107 codes for documenting harmful or unintended reactions to drugs or substances taken as prescribed or directed. These are not poisonings but side effects from proper use of medications. Coders must identify the specific drug involved and ensure that documentation supports an adverse effect rather than misuse. Reporting adverse effects correctly prevents claim denials and ensures accurate clinical data collection. No external cause code is required.
