These plaques are found in the intima of large- and medium-sized arteries. 440 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 440.0 Atherosclerosis of aorta 440.0 is a specific code that can be used to specify a diagnosis 440.0 contains 10 index entries ICD-9-CM Diagnosis 440.1 Atherosclerosis of renal artery 440.1 is a specific code that can be used to specify a diagnosis 440.1 contains 7 index entries ICD-9-CM Diagnosis 440.2 Atherosclerosis of native arteries of the extremities 440.2 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 440.20 Atherosclerosis of native arteries of the extremities unspecified 440.20 is a specific code that can be used to specify a diagnosis 440.20 contains 15 index entries ICD-9-CM Diagnosis 440.21 Atherosclerosis of native arteries of the extremities with intermittent claudication 440.21 is a specific code that can be used to specify a diagnosis 440.21 contains 5 index entries ICD-9-CM Diagnosis 440.22 Atherosclerosis of native arteries of the extremities with rest pain 440.22 is a specific code that can be used to specify a diagnosis 440.22 contains 2 index entries ICD-9-CM Diagnosis 440.23 Atherosclerosis of native arteries of the extremities with ulceration 440.23 is a specific code that can be used to specify a diagnosis 440.23 contains 7 index entries ICD-9-CM Diagnosis 440.24 Atherosclerosis of native arteries of the extremities with gangrene 440.24 is a specific code that can be used to specify a diagnosis 440.24 contains 19 index entries ICD-9-CM Diagnosis 440.29 Other atherosclerosis of native arteries of the extremities 440.29 is a specific code that can be used to specify a diagnosis 440.29 contains 1 index entry ICD-9-CM Diagnosis 440.3 Atherosclerosis of bypass graft of the extremities 440.3 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 440.30 Atherosclerosis of unspecified bypass graft of the extremities 440.30 is a specific code that can be used to specify a diagnosis 440.30 contains 3 index entries ICD-9-CM Diagnosis 440.31 Atherosclerosis of autologous vein bypass graft of the extremities 440.31 is a specific code that can be used to specify a diagnosis 440.31 contains 3 index entries ICD-9-CM Diagnosis 440.32 Atherosclerosis of nonautologous biological bypass graft of the extremities 440.32 is a specific code that can be used to specify a diagnosis 440.32 contains 3 index entries ICD-9-CM Diagnosis 440.8 Atherosclerosis of other specified arteries 440.8 is a specific code that can be used to specify a diagnosis 440.8 contains 1 index entry ICD-9-CM Diagnosis 440.9 Generalized and unspecified atherosclerosis Thickening and loss of elasticity of arterial walls. Atherosclerosis is the most common form of arteriosclerosis and involves lipid deposition and thickening of the intimal cell layers within arteries. Additional forms of arteriosclerosis involve calcification of the media of muscular arteries (Monkeberg medial calcific sclerosis) and thickening of the walls of small arteries or arterioles due to cell proliferation or hyaline deposition (arteriolosclerosis). 440.9 is a specific code that can be used to specify a diagnosis 440.9 contains 3 index entries
