Signs of infection require to be considered such as development of grey or yellow tissue, purulent discharge, unpleasant smell, sinus, undermined edges and exposure of bone or tendon.Identification of diabetic foot in medical databases, such as commercial claims and prescription data, is complicated by the lack of a specific ICD-9 code for diabetic foot and variation in coding practices. The following codes indicate ulcer of the lower limb or foot:
707.1 Ulcer of lower limbs, except pressure ulcer
707.14 Ulcer of heel and midfoot
707.15 Ulcer of other part of foot
707.19 Ulcer of other part of lower limbOne or more codes, in combination with a current or prior diagnosis of diabetes may be sufficient to conclude diabetic foot:

250.0 Diabetes Mellitus
250.8 Diabetes with other specified manifestations

Classification
Diabetic foot ulcer is a complication of diabetes. Diabetic foot ulcers are classified as either neuropathic, neuroischaemic or ischaemic.Doctors also use the Wagner Grades to describe the severity of an ulcer. The purpose of the Wagner Grades is to allow specialists to better monitor and treat diabetic foot ulcers. This grading system classifies Diabetic foot ulcers using numbers, from 0 to 5. Wagner Grades 0 through 5 are as follows:
0. No diabetic foot ulcer is present, but there is a high risk of developing one. 1. A surface ulcer involves full skin thickness, but does not yet involve the underlying tissues. 2. A deep ulcer penetrates past the surface, down to the ligaments and muscle. There is no abscess or bone involved yet. 3.
A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system.During a right bundle branch block, the right ventricle is not directly activated by impulses travelling through the right bundle branch. The left ventricle, however, is still normally activated by the left bundle branch. These impulses are then able to travel through the myocardium of the left ventricle to the right ventricle and depolarize the right ventricle this way. As conduction through the myocardium is slower than conduction through the Bundle of His-Purkinje fibres, the QRS complex is seen to be widened. The QRS complex often shows an extra deflection that reflects the rapid depolarisation of the left ventricle followed by the slower depolarisation of the right ventricle. Incomplete right bundle branch block
Incomplete right bundle branch block (IRBBB) is an conduction abnormality in the right bundle branch block. While a complete RBBB has a QRS duration of 120 ms or more, an incomplete block has a wave duration between 110 and 120 ms. It has a relatively high prevalence, a study conducted on young Swiss military conscripts with a mean age of 19 years found a prevalence of 13.5%. It affects patients of all ages, more commonly males and athletes, however is not always a benign finding. Therefore, if abnormalities are detected on the physical exam, further testing should be done to exclude heart disease.There is no consensus in the literature regarding criteria for diagnosis.
