Specific code 2014 ICD-9-CM Diagnosis Code 440.9
Generalized and unspecified atherosclerosis
  • Billable Code
  • Adult Only Dx (15-124 years)
  • Short description: Atherosclerosis NOS.
  • ICD-9-CM 440.9 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.

Disease Synonyms
  • Atherosclerosis artery
  • Atherosclerosis of artery
  • Atherosclerosis, generalized
  • Generalized atherosclerosis
Clinical Information
  • 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 Excludes
  • arteriosclerotic cardiovascular disease [ASCVD] (429.2)
Applies To
  • Arteriosclerotic vascular disease NOS
ICD-9-CM Coding Information
  • 440.9 is only applicable to adult patients aged 15 - 124 years inclusive.
Convert to ICD-10-CM: 440.9 converts approximately to:
  • 2014 ICD-10-CM I70.90 Unspecified atherosclerosis
    Or:
  • 2014 ICD-10-CM I70.91 Generalized atherosclerosis

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 440.9 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
