Differences in Disease Capture by Rank for ICD-9-CM and ICD-10-CM for Causes of Mortality: Heart Disease and Top Five Cancers
| Diseases Related to Mortality: Heart Disease and Cancers | ICD-9-CM Rank | ICD-10-CM Rank | Explanation |
| Angina | 4 | 5 | Both similar but I-10 has a unique code for angina pectoris with documented spasm |
| Diseases of arteries: atherosclerosis of aorta, renal artery, extremities, etc. | 4 | 5 | I-10 differentiates between right and left leg |
| Diseases of arteries: aortic aneurysm, aneurysm of upper extremity, etc. | 3 | 5 | I-10 more specific differentiating between right and left |
| Rheumatic heart disease and rheumatic fever | 4 | 5 | Similar for both but I-10 provides more specificity for other and unspecified mitral valve diseases |
| Cancers | |||
| Malignant neoplasm of lung | 2 | 5 | I-10 much more specific and breaks out each anatomic category for both right and left side |
| Malignant neoplasm of breast | 3 | 5 | I-10 much more specific and breaks down category by right and left side, male and female |
5= Diagnosis is fully captured by the code/codes
4=Diagnosis is almost fully captured by the code/codes
3=Diagnosis is partially captured by the code/codes
2=Diagnosis is less than partially captured by the code/codes
1=Diagnosis is not captured by the code/codes
