| 7115 Thrombo-angiitis obliterans (Buerger’s Disease): | |
| Lower extremity: Rate under DC 7114. | |
| Upper extremity: | |
| Deep ischemic ulcers and necrosis of the fingers with persistent coldness of the extremity, trophic changes with pains in the hand during physical activity, and diminished upper extremity pulses | 100 |
| Persistent coldness of the extremity, trophic changes with pains in the hands during physical activity, and diminished upper extremity pulses | 60 |
| Trophic changes with numbness and paresthesia at the tips of the fingers, and diminished upper extremity pulses | 40 |
| Diminished upper extremity pulses | 20 |
| GENERAL RATING FORMULA FOR DISEASES OF THE HEART: | |
| During and for three months following myocardial infarction, confirmed by laboratory tests | 100 |
| Thereafter, use the General Rating Formula | |
| Workload of 3.0 METs or less results in heart failure symptoms | 100 |
| Workload of 3.1-5.0 METs results in heart failure symptoms | 60 |
| Workload of 5.1-7.0 METs results in heart failure symptoms; or evidence of cardiac hypertrophy or dilatation confirmed by echocardiogram or equivalent (e.g., multigated acquisition scan or MRI) | 30 |
| Workload of 7.1-10.0 METs results in heart failure symptoms; or continuous medication required for control | 10 |
Note (1): The ankle/brachial index (ABI) is the ratio of the systolic blood pressure at the ankle divided by the simultaneous brachial artery systolic blood pressure. For the purposes of this diagnostic code, normal ABI will be greater than or equal to 0.80. The ankle pressure (AP) is the systolic blood pressure measured at the ankle. Normal AP is greater than or equal to 100 mm Hg. The toe pressure (TP) is the systolic blood pressure measured at the great toe. Normal TP is greater than or equal to 60 mm Hg. Transcutaneous oxygen tension (Tc PO2) is measured at the first intercostal space on the foot. Normal Tc PO2 is greater than or equal to 60 mm Hg. All measurements must be determined by objective testing.
Note (2): If AP, TP, and Tc PO2 testing are not of record, evaluate based on ABI unless the examiner states that an AP, TP, or Tc PO2 test is needed in a particular case because ABI does not sufficiently reflect the severity of the veteran’s peripheral arterial disease. In all other cases, evaluate based on the test that provides the highest impairment value
