What does ICD-10-CM code I25.10 mean?
I25.10 represents Atherosclerotic heart disease of native coronary artery without angina pectoris. This cardiovascular condition is classified under Chapter 9 (Diseases of the Circulatory System) and is one of the most commonly coded circulatory system diagnoses. This condition is commonly abbreviated as CAD, Coronary artery disease in clinical documentation. Coders frequently reference this code as cad icd 10, cad icd 10 code, icd cad, or cad with stent icd 10.
This is classified as a chronic condition requiring ongoing management and monitoring. Depending on the clinical diagnosis, management may involve niacin, pravastatin, fenofibrate. Refer to current clinical guidelines and provider documentation for treatment decisions.

Guideline notes and coding considerations
Important Guideline Note
Assign I25.10 only when documentation clearly supports this diagnosis. Review the excludes notes and ensure no conflicts with other assigned codes.
- Use Additional Code: code, if applicable, to identify:; coronary atherosclerosis due to calcified coronary lesion ( I25.84 ); coronary atherosclerosis due to lipid rich plaque ( I25.83 )
Learn the underlying rules in the ICD-10 Coding Guidelines, Combination Code Requirements.
Documentation tips (what coders should confirm)
- Verify the clinical documentation supports the use of I25.10
- Query the provider for greater specificity if clinical details suggest a more precise code
- Use additional code: code, if applicable, to identify: | coronary atherosclerosis due to calcified coronary lesion ( I25.84 ) | coronary athe
- As a chronic condition, document current status and treatment at each encounter for risk adjustment

The condition should be actively addressed during the encounter using MEAT criteria: Monitored, Evaluated, Assessed/Addressed, or Treated. Simply listing the condition in the problem list without clinical action does not satisfy documentation requirements.
Documentation should clearly describe the clinical condition represented by I25.10 (Atherosclerotic heart disease of native coronary artery without angina pectoris). Include relevant clinical findings, diagnostic test results, provider assessment, and the treatment plan. The diagnosis must be supported by the medical record and not based solely on lab results without clinical interpretation.
